Mineral Oil Cooled PC

Project Ready DIY Kit for the PC Enthusiast

Unfortunately our mineral oil aquarium PC kit project has been alleged to infringe on the patents held by a company who holds several patents related to mineral oil cooling of PCs. They offered to license this technology back to us. We decided to shut down this project instead, because the licensing cost was infeasible for this type of project, and we did not want to set a precedent of paying to license something we conceived and developed on our own.

Here at Puget Systems, this project has never been motivated by profits. It is a project that we have had a lot of fun with, and that we enjoyed using to enable the enthusiast community to do new and interesting things. As such, regardless of how we feel about the validity of this patent pressure, we cannot devote the time, finances and energy to take up that battle. We have a very successful business manufacturing high performance and high quality PCs and workstations, and will be focusing our energy there going forward. We will continue to host information, photography, and videos about our mineral oil PC kits, but we will be unable to continue to sell the kits themselves. We look forward to seeing what you all come up with as we pass off the torch to each of you!


is there any place else that will sell the kit or at least the parts i am planning on making one for a senior project but the kit is shut down

As far as I know, there are no other aquarium kits that you can purchase. Your best bet may be to do what our very first aquarium system was where you just get an aquarium tank and a motherboard tray (FrozenCPU sells trays or you could salvage from an old chassis) and mod it all together. I believe all we really had to do was cut a piece of acrylic to fit the top ring of the aquarium tank and fasten the motherboard tray to that.

Check out the History tab for pictures. When we did it it wasn't perfect (I remember there being some really big gaps in places), but it worked.

thank you ill give it some thought and possible do that. the main concern was having the custom motherboard tray and the cooling components.

Can't you just work around the patents, surely someone can't patent a waterproof or oil proof PC case?

i know how you feel, i built a box 12"x12" that held goo (any color and seemed to favor daylight) it had a capacity of over 900 TB and could save and read the data (about 1tb ) in about point.32 seconds, the power consumption was a little higher than i wanted during read and writes, about point.9 volts but it was ok until i do further research. i had sent a paper and demo video to several agencies and no one wrote back but did have some guys come and say i was infringing on their patents bla bla bla ... and said i had to hand over my device. really if it wasnt for the guns and crap i would have never let them have all my stuff, thankfully im able to use my box of goo memory here at home and have made a few for friends

Posted on 2018-04-25 15:26:13

that's pretty cool.. where do you get the goo?

Posted on 2018-08-15 21:50:00

how sad. I did 10 various builds 2 years before 90% of the hobby knew what an oil bath pc was. I perfected the design, and nearly sold it to microsoft under patent. I wonder who has the patents now...

If there are no other aquarium kits to be purchased HOW could there be an infringement issue?

That kind of patent holders is not interested in building anything. They just wait for someone else to develop something, then they clamp on an leach the profits.

Patent law is not compatible with capitalism. Patents are monopolies created by the government.

Posted on 2015-10-04 18:04:27

True. Corporations aren't compatible with capitalism either nor is government.

Posted on 2015-11-07 22:44:50

thats anarchy, not capitalism.

Posted on 2015-11-20 01:55:43

Another word for true/pure capitalism.

Posted on 2015-11-21 08:42:05

simply false, anarchism generally is socialistic. capitalistic anarchy is sometimes debated as not even real, thats how false your statement is.

Posted on 2015-11-24 20:51:37

and with socialistic i mean that it holds values similar to socialism, anarchism grew hugely with the grow of socialism because the anarchists believed socialism could not be achieved trough a state. capitalism is a economic system, it has a sense of private property etc that could never exist within anarchy.

Posted on 2015-11-24 21:02:25

Capitalism definitely requires a governing entity to enforce the rule of law. Markets thrive on certainty, and collapse on uncertainty. Having codified laws and a strong enough enforcement mechanism to make sure the laws are followed creates certainty. This is common sense, really. Doesn't matter whether you're a consumer, business owner, or investor: You're not going to buy if you, for example, have no guarantee of product quality. People are less likely to buy from stores that have a no return policy, for example.

I don't think you quite understand what a corporation is. The government itself is a corporation. A non-profit is a corporation. An LLC or LLP is a corporation. If you run a business, it's an incredibly bad idea to not be incorporated (You can risk losing all of your personal possessions and life savings if you don't. All it takes is for one of your employees to cause a bad car accident, or some other catastrophe beyond your control, and you could be sued for well more than your business's total net worth, which means the claimant can go after your personal possessions next. Incorporating shields you from that liability.)

Corporations today even more so, as the power to obtain monopolies and manipulate markets is far diminished from that of earlier ones. The very first publicly traded company, the Dutch East India Company, had the biggest monopoly the world has ever seen, had its own very powerful Army and Navy, had the power to wage wars, and jail and even execute people who didn't pay their bills. At its peak, the Dutch East India Co was worth today's equivalent of 8 trillion dollars. Runners up: Mississippi Company at 6.5, and South Sea company at 4.3.

Dutch East India Co was worth roughly the same as the top 20 largest companies by market cap in the USA combined. Saudi Aramco is the wealthiest today at 2 trillion, and was worth $4.1 trillion just before OPEC totally lost its ability to corner any markets (primarily because North America has 1/3rd of the world's oil reserves, and we've only been able to tap them with recent technology advancements.)

I disagree. Capitalism has little to do with this, it's government and political corruption.

Posted on 2016-01-03 22:08:34

Capitalism is where access to trade is controlled by private owners for profit, in this case it fits. The control is helped by laws, but the ultimate control is still granted to private entities.

I. B. Halliwell

Patents are in the US Constitution before big business and today's corruption. Our founding Fathers came up with the need to protect a person's idea. Just saying the original idea is good. Today's implementation has a lot of catching up to the ideals of our Fathers.

Posted on 2017-08-01 11:25:16

"Patents are in the US Constitution before big business and today's corruption."

This is just something people say, or that the founding fathers couldn't have foreseen how "big and corrupt" corporations could get.

It's totally false.

The founding fathers were born after the largest business to ever exist was already a thing, and gigantic monopolies that are no longer even possible today were still a thing when the founding fathers were active. You think today is corrupt? Dutch East India Company was worth today's equivalent of $8 trillion, had war powers (along with a very powerful Army and Navy,) arrest powers, execution powers, and had a blanket maritime trade monopoly over practically the entire eastern hemisphere, and part of the western as well.

Furthermore, the colonists at the time were already used to dealing with a trade monopoly of their own, enforced by the crown, and they hated it. The founders themselves were very much capitalist, which can be observed in their writings. Especially Ben Franklin's. (Though capitalism didn't have a name at the time, and contrary to popular belief, Adam Smith didn't invent capitalism, nor did he even name it, rather he just observed how trade worked and documented it in his book "The Wealth of Nations". Capitalism didn't get a name until over a hundred years later when Karl Marx's book, Das Kapital, was translated to English in 1888, and the translator used that word to describe it in the book.)

The problem you're seeing with patents today didn't come about all at once. Patent law has, over time, gradually changed to what it is now by congress, with virtually each change going gradually further into its current state.

Posted on 2018-08-28 09:12:31

Rakeesh you are so right. One of the problems is that people do not know the processes involved in applying for a patent or the purpose of getting a patent. One of the biggest problem today is the money that it takes to get a patent and how you have to jump through flaming hoops. The U.S.P.O. If I am correct was created by congress and given a set of rules to work by but also they gave them a level of autonomy. Which means that they have the ability to make there own rules. So they become self governed and have self control this allows them to operate as they see fit . Then congress passed a law, rule, statute saying that they are to be self funded and what do you have. Well I have 4 Patents that I would like to apply for but cant because the process is so complex and cost prohibitive thus becoming the domain in which the only big corporations get to play in. Well now I said I have 4 patents that I would like to apply for so let me tell these ass clowns I am an amputee and have things that would improve the lives of some of us, but making $1600 a month I can not afford $10,000 plus to apply for the patent and then the money that it would take to pay for testing buy the F.D.A because it is a medical device. So what am I do, talk to a corporation to get help Yea right they will screw me and make what ever it is they will make as for me they do not care. So I have made my devices and use them and all other amputees have to do without the benefit of my intellectual property. Which is cold but I refuse to let a corporations make millions off my intellectual property again (YES I DID SAY AGAIN). So you ass clowns that think it is just the corporations no it is not, It is mostly the bureaucratic machine and lazy politicians and don't forget the pro corporation courts that all work to prohibit the little guy from profiting form their hard work and ingenuity. Patents are to protect the inverter and prohibit others from using your Idea and profiting with out having to conceptualize, prototype build, test, refine and build again
think about it you make a widget and and start to produce it and sell it, you have to use the profits to advertise buy more material. It is a slow process maybe you can get a loan to expand but then a company with deep pockets comes in and starts to make it cheaper and has a massive advertising budget distribution network BLA BLA BLA and their sales exceeds yours, you will be doomed to fail before you even got started. But with patent protection you could stop them and even get paid for damages that would allow you to expand. NO the company is only protecting its self and its intellectual property. Now to get to the hart of the issue dose the company that holds the patent produce a product for this market if not then I have to ask why, if they have not, do not and will not then let someone make it if they have a market for it. They can take a small royalty and we will have a product that we can use.

I was about to have to comment myself, but I'm glad to see at least one person here likes to read.

Posted on 2021-05-24 23:56:01

It's absolutely spectacular to me just how confident people can be on things they've clearly never researched in any real detail. For instance the ubiquitous (at least here in the US) belief that anarchism and capitalism are in any way compatible, or even related. Or this strange belief that patents are a product of the government infringing upon private property owners, when the purpose of a patent is to extend property rights to ideas; a move that exclusively benefits industry at the expense of public good.

Like cmon guys, what do you think a government is? You have at least some power over the government, and none over the industry except through the government. Corruption is what you get when a private actor gains control over the state, not just something that spontaneously occurs wherever there's a government. The state is neither good nor bad. It's a tool meant to elevate our common conditions and provide services that can't be achieved individually. It's the only mechanism we have for guaranteeing things we all want to have like water and healthcare. What matters isn't what the government controls, but who controls the government. Is it the public? Is everyone allowed to vote? Are our representatives obligated to obey that vote? If the answer is no to any of those questions, the solution isn't to give up on government, it's to fix it. Get involved, and try to make the world a better place.

Monopolies and patent hoggers are to capitalism, as governments are to socialism and communism.

Legal concerns. We are trying to be careful - this aquarium kit stuff was only ever a fun project, which we made available to the public because of demand (we hadn't planned on that when we made our first design and the original video about it). We have a much bigger business building high-quality computers, and cannot risk that business over this issue. I know it sucks, and I know that patents like this (where there is prior art, etc) suck... but it is the law currently, and we aren't in a position to do anything about that.

Posted on 2014-11-21 18:24:14

Well then we just have to make our own blueprints and post it somewhere.

Posted on 2014-12-12 12:21:59
Andrew DeLong

It's very understandable that your business cannot give out the blueprints out of legal concern. But is it possible to point to a third party that - not tied to your own business in any way - would have a similar item on their docket? I mean, I'll design and order the manufacture of parts myself if I have to, but I'd prefer to buy a pre-assembly from some type of OEM if possible.

Posted on 2014-12-26 17:00:05

I am not aware of any other company or group that was providing a similar kit. If anyone else knows of one, though, please feel free to link it here (I think that would be okay, especially if not coming from our company).

Actually you should be able to give parts lists and even show people how to do it legally, the patent only blocks the sales and profit from selling. So give em everything and that's how you stick it to them!

Patents and ideas is a funny thing, i build my first oil coled pc in time for The Gathering in 2000. it was called Draugen and you can still find pictures of it if you search thru the Internet Archive after oil.jpg

Posted on 2015-04-27 20:07:20

That would be prior art for any case. If you could post this information with dates and this could be useful to anyone threatened in the future by the non-practicing entity. Prior art searches are usually limited to certain channels, such as prior patents, scientific publications, etc. Blogs and discussion boards are not in the realm of prior art, but even science fiction can be brought forth as prior art. One noted case of prior art from science fiction is the waterbed. When someone tried to patent a waterbed, the patent was actually overturned due to the sci-fi authors detailed description of the invention in their fiction.

The thing with patent trolls, they are paper tigers. I hope you talked to an attorney before shutting everything down. In some cases, litigation attorney fees will be paid by the losing party the lawyer may take a case knowing he can bill the ones bringing the litigation for infringement.

Posted on 2015-06-03 18:19:47

Looked at the patent, and I would highly recommend talking to a lawyer if anyone can provide blog posting, groups selling kits prior to 2005, enthusiast articles. Their claims are very broad, which can backfire and be taken down if anyone has anything close to their description in these sources being regarded as common knowledge and unpatentable. I just finished my first patent, which we do plan to practice with in biopharma.

Well, you can always hold onto your tech, tweak it in secret, and wait until the patents expire.

Just sell it as a open air test bench. The only difference is the fluid going to water blocks and not into the tank. You wouldn't have to change anything other than the instruction manual.

Sigh... I was slowly acquiring the parts to build a ATX and had gotten my hands on an Eclipse the 12 gallon tank.. and now to find out that they are being jackasses and doing this to you... you were no threat to them and they don't deal with the same things... they are just being bullies.

So now do I just make this a fish tank or continue on...

I could possibly place the motherboard at the bottom of the tank and and just lean it against the side, if I get extenders it should minimize wicking, possibly could make a bracket for hard drive to keep it out of the mineral oil.

The pumps you used and the radiator, did you manufacture those yourself or can you legally tell us where you acquired them?

Posted on 2014-12-01 19:45:40
Josy Sclei

I know they used a regular copper watercooling radiador, and a regular watercooling pump too. Look at their timeline, I think there is even the model they used.

Posted on 2014-12-01 22:05:30

The pump and radiators are all standard liquid cooling components. The only thing is that the pump has to be a bit more powerful than you expect since oil is much thicker than normal liquid cooling fluid. Specifically, our kits were using the Swiftech MCP35X pump. For the radiators, we used the Watercool MO-RA3 360 LT 9x120 (still available on our parts store: http://www.pugetsystems.com... and http://www.pugetsystems.com... or the Swiftech MCR220-QP-K 2x120mm radiator depending on the cooling kit.

how well would a D5 Vario pump handle this?

and also could you point us to the other company, so i may know who not to buy them off!

Posted on 2015-01-02 10:47:50

That pump should work just fine. It looks like it can pump a max of about 5.3GPM, whereas the Swiftech MCP35X we used could do a max of about 4.75GPM. Unless you are pumping through a lot more radiator than we did or want a really high flow (which actually isn't a good thing since the oil requires more time in radiators to cool down compared to normal liquid cooling fluid) that pump should have no problem.

As for the other company... things are a bit sensitive right now so we actually took their name off the post above. From my understanding, however, they don't have any actual commercially available products so there isn't really any risk of you accidentally supporting them.

Ya I understand. But just selling just the acrylic base without the fittings, radiator, and stuff would be breaking the patent. The open air bench that pugetsystems sell is it designed the same?

Posted on 2014-12-12 04:33:56

To the extent that a patent prevents the sale of common components assembled in relatively obvious ways, that patent is not enforceable. Receiving a patent is not the final word on its legality and does not give the patent holder license to sue everyone for everything remotely similar to their patent. That is not how the law of patents works.

Instead of selling the Kit as a whole can you part it out and sell individual components under the guise of them just being for a standard PC build and then what the consumer does with it is up to them?

The patent system has been broken for a long time. A German invented the first oversize tennis racquet (and had 18 of them made). His racquets "disappeared" from the German patent office and a broad patent was later granted by the American office to Howard Head for Prince. The German patent authority refused to recognize the American patent due to prior art but the damage was done nonetheless. Prince made a ton of money and no one remembers that German inventor today or his racquet. I had to create a Wikipedia page based on information from an article that could only be found via the WayBack Machine!

Watch the film Tucker sometime. The patent system, like IP laws in general, favors people with money and influence rather than inventors. Instead of it being a matter of who did it first it's a matter of who can convince the system first. I am also under the impression that the support of large corporations for changes designed to allegedly combat patent troll companies is designed merely to better enable large corporations to control things more with patents. Why bother paying a subsidiary to troll when you can do it yourself, I suppose.

Posted on 2014-12-09 21:53:48

The concept of using non-conductive fluid can not be used for a patent. Their specific use and how they go about doing this can be patented. Or if they create a customer liquid to do the job.

Using mineral oil for the purpose is not new, is not their original idea.

I believe they have no grounds to claim that their patent covers what you are doing.

Posted on 2014-12-11 05:56:18
Brandon Rinebold

They don't have to. They only have to keep dragging you into court until you give up and pay them to go away or just shut down so they can claim 'the last company who infringed out patent was shut down when they wouldn't pay us'.

Welcome to the US patent system.

Posted on 2015-02-14 06:22:35

When the first case is demonstrated to have no merit, there cannot be a second claim on the same basis. Eventually, it becomes abuse of the court system, which an attorney is obliged to refuse or else risk being disbarred.

Patent trolling makes me angry but I suppose the most constructive thing to do is to deny LCS any profits and brainstorm my own piecemeal. Like this. This was a first attempt I'd done in 2006 that failed as the plex cracked on the bottom. But it was FUN to build it. Puget rocks. You inspire me!

If you want to try to find a way around licensing, please feel free to contact me. I have served as an expert witness in a dozen different patent infringement cases. There is plenty of prior art to invalidate the patents. Ever hear of the Cray 2?
For a little background, I do have a Ph.D. in Chemical Engineering and have over 20 issued patents. I would hate to see a good company abandon work for reasons like this.

i just watch the video of LinusTechTips and i made my choise to make one of mine but with vegetable oil i think it works the same i hope you you come back with your kits they look very awsome! great job all these year it's sad to think i just look the video log and you are not selling them any more!!!

hang in there i know you can make a comeback sooner

regards and cheers from MEXICO

A word of caution, I have heard that vegetable based oils go rancid over time - I think that is why everyone uses non-organic oils instead. Vegetable oil also isn't clear, so I would think it wouldn't look as nice.

I started my company to make immersion cases a little over 4yrs ago. I have been working odd jobs to pay for the testing and research to make a modular immersion case that I can put a lifetime warranty on. I have pored over all of hardcore's patents and dells and others that are close to get my patent done. and the patent linked above is the wrong one. us patent 20080017355 A1 would be the one that would be closest patent they have to be violated. I have just recently filed my patents. It is a shame to see another innovator in immersion tech get pushed about. To any one interested I am hopeful Crypt'N will have its first beta model avail before the end of the year.

also i should state for any trolls that you can not try to file a patent on that. something similar has already been filed and expired years ago before computers were a thing but stills falls within its claims and I would list it for you but I am having trouble at the moment finding the right one but I know I have read it once. well any how, if I ever find it again, and remember this forum, I will come back and link it, but if some one else finds it first fell free to add it.

I don't know a ton about patents, but this was just issued recently I think... so I imagine it won't expire for many, many years.

Posted on 2014-12-21 23:20:42

US Patents are supposed to only last for 17 years after they are created, however they can be extended (nearly indefinitely). Unfortunately, this looks like a gov't contractor, and the submersion system seems to have been meant for gov't data centers. So not only is this not private sector work, it's essentially a just ploy to keep the gov't paying them, and ONLY them...

Posted on 2015-06-04 01:02:10

2007 filed wont exp till 2027 if they keep paying the patent fees. no this is not a classified patent that can be extended past 20 yrs.

We appreciate your support, but it is just not a fight worth having to us. This was never something we made a lot of money off of (we didn't want to - in fact, we had never planned selling kits or anything when we made our first video years ago). Even if we had all the monetary costs covered, somehow, it would still be a big commitment of our time and focus.

William: if this problem was taken care of for you, you wouldn't sell them to those of us who have always dreamed of having your kit?

Posted on 2015-03-19 18:06:39

That is honestly something I cannot answer - its above my pay grade :)

If this had not come up I believe we would still be selling the kits, but with us having ceased production of the tanks (we used aquariums originally, but the models we used went out of production and so we had to start contracting with a company to make tanks the right size and strength) and having emptied our inventory of related parts... it would take a lot of effort to get it all going again. Since it doesn't look like the legal block will be going away any time soon we haven't even thought of what would happen if it did.

I looked into it, its an uphill climb. A company bought out hardcore Computers, Inc and they no longer make PC's. They are making data center solutions and obviously going after GSA contracts. Their pockets are deep at this point and i am sure they can hold it up in court for a long time to come if anyone challenged their patent. I agree, it's just not worth it.

how the hell can anyone take a patent on this? thats just ridiculous...

provisional filed 2006 patent not filed till 2007, makes a difference to some people, not trying to get nit picky. And whats being patented is the how. the principal itself is not patentable.

Posted on 2015-07-26 22:58:07

Puget Systems: In regards to the patent mentioned, I don't know if you guys are legal wizards, or have consulted your lawyers, but a legal precedent called Prior Art may apply. If the patented invention is already known, and you can provide evidence that it was, the patent is invalid. All you need is proof that someone, somewhere, sometime, either came up with the idea, or constructed a similar machine at one point to make the patent invalid. According to a recent post of yours, the patent was "recent," though you guys have been playing with this stuff for the last 8 years. A quick search of the US Patents database shows that the patent, and your work, started at or around the same time in 2007. (fancy that!) They even quote you in their application. A quick google search for mineral oil submersed cooling for articles prior to 2006, shows a number of people interested in this from before 2003, and I even found a Master's Thesis in 2002 outlining the specifics of oil-based submersion cooling. I'm willing to bet $$$ that you could easily get this patent thrown out and resume selling and developing, what I'd imagine to be, a very profitable item for you.

Don't fear them. Fight back.

Desthro: What we need is a computer enthusiast/lawyer to do this work pro bono for Puget Systems. Obviously Puget Systems did this as a hobby and we can't put all the iotas on them to carry the fight forward. I might be able to find a lawyer who could take this up if I ask around. The fact is, that if we want to see the future of this product, we would have to all do the work, everyone should ask their lawyer friends if they have them.

This is very, very unfortunate. I very fondly remember reading all about this project and being excited for updates. I wanted to make something like this some day as well, sort of as a showpiece, among other things.

Now it looks like I'll be doomed to making something that looks like a piece of garbage because eight years of work was erased. If a patent can be made which shuts down the only source for a product, then the patent system is completely broken.

I'm setting up a system with a 12.000 BTU A/C unit. I was thinking of submerging the evaporator in the oil bath with the computer. I would use a couple of pumps to discharge the oil flow directly on the CPU and GPU's. My question is "at what temperature would the oil become too viscous for a Swiftech 35x to move it?"

Posted on 2015-05-02 00:35:44

You would have to get it really cold to not be able to pump it at all. We did some testing using a liquid chiller from Koolance (I believe it was this model: http://koolance.com/exc-800... and while the oil got very viscous, the pump never stopped pumping. It did turn into a trickle though, so at a certain point you might be hurting things more than helping.

It's been a while, but I want to say we started to see a drop in flow unitl it became a trickle at about 10C. I believe we eventually got the oil down to -5C, but that took a long time without the computer under any load. At 10C, condensation was a huge problem. Everything that was in the oil was fine, but our design only has the motherboard mostly submerged so you could get to the ports easily. The problem was that where the motherboard came out of the oil we were getting condensation right on the motherboard which isn't exactly ideal.

Unless you do something extreme and get the oil down that cold, I don't think you'll have too much of a problem pumping the oil around.

Posted on 2015-05-04 17:59:54

Thanks Matt. My goal is to go sub zero on the CPU and GPU's so I think I will have to stick with water and insulation.

Posted on 2015-05-10 01:29:07
John Muldoon

I just had an idea. I will set up the system as a chilled water system as I originally planned but submerge the computer in oil. That way I can realize the low temps of water without the worries of condensation.

Posted on 2015-05-12 13:12:43

Do you think you could provide some high-resolution photos of the cut acrylic parts, preferably on top of grid paper, taken as top-down photos? This would be really useful for historical purposes.

Posted on 2015-05-21 23:29:33

So has anyone used transformer oil (dielectric silicon-based fluid)? Yeah it is $30 a gallon but wouldn't it be less likely to eat away at the rubber wire casings than mineral oil? I am very upset about the shut down of the kit but planned on making my own one piece tank and motherboard tray anyway out of semi-rigid polyurethane, but your specifications were my greatest inspiration. The U.S. Patent office is obviously just following their tradition of technology suppression by any means necessary. Imagine the stink in the market if all water-cooled trash was left by the wayside. Wet works is coming as soon as the Internet is not free. Hopefully you guys are doing the same as me and collecting massive amounts of technical data on this kind of thing. Not to make money, but to insure the information doesn't disappear or get buried from the public eye like the magneto crank generator, the electric car, the water car, and of course Thorium fuel. Submersion is the future.

Posted on 2015-05-22 09:59:34

I found this document about the Cray-2 system from 1985. It clearly states that the system use immersion cooling in the first paragraph describing the system: http://archive.computerhist...

Why not re-open as a corporation (LLC) and let them sue you? As a LLC you are not personally liable, and chances are they are trying to scare you out of business (and it worked). Anyone can send a cease and desist letter, it doesn't mean they own your work. It sounds like you aren't infringing on their patents. Find a lawyer to talk to, go back in business.

Posted on 2016-06-16 01:40:55

This was just a fun project for them, not their business. They have stated multiple times that they need to focus their time and energy on their their existing, successful custom computer business and not fighting a possibly endless battle in court. After all of the videos, pictures, updates, and FAQ's they have provided its really frustrating that people are still expecting even more from them. The whole point of this is to be a DIY project. As in do it yourself. If people are really interested in this they should take the copious amount of information still available on their website and take the time to build one for themselves. I'm sure seeing the community keeping this alive and making their own custom builds will bring more satisfaction to any of the developers involved in this project than winning a case in court would.

Posted on 2016-07-10 17:38:34

There should be a way to appeal that patent. 1st they didn't invent mineral oil, nor PC systems, nor aquariums. 2nd they don't own science nor material properties (nobody should be allowed to "own" Nature's / Universe's properties anyways, a discovery is not an invention). 3rd, if it was only for the use of the idea of emerging a PC tray into a container of mineral oil... But they don't even do it !! So if someone come up with this idea (as I did before searching for it and fumbling onto Puget systems), they won't be allowed to do it because of a flawed patent system, from then on being a real barrier towards human technological evolution in regards to applications tied with some material properties they didn't invent : this "company" is essentially "parasiting" a market where it's not even an active participant, and should get its patent canceled.

BTW, did they file for such patent internationally ? Fortunately, patent laws aren't the same everywhere (USA is probably THE country where companies are abusive with such otherwise basically legitimate legal tool, where corrupting the government is so easy so as to put forth such patenting ill-devised rules... i.e. patenting the human genome should be illegal, as I wrote a discovery of a natural / biological / material property is not an invention).

I too, was excited to discover this product and then disappointed to find it had been discontinued.

Having read through the info and comments on this site, it looks to me as if the best way to take this forward is to create an Open Source project to house all relevant knowledge, designs and resources that might help someone build one of these for themselves and to act as a hub for the community arising.

I'm thinking that if the project is not-for-profit then there is no point in trying to sue it. I'm also thinking that if the project is popularising the idea of mineral oil cooled PC's, then this can only serve to increase the patent holder's business as more people will hear about the technology and take it more seriously.

Handled well, the project might even be able to develop cordial relations with Puget and the patent holder.

Who knows where that might lead...

Interested in your thoughts.

2005 PAX (Penny Arcade Expo) CPU Magazine Case Mod USA Finals had SEVERAL mineral oil cases. Check CPU Magazine Case mod articles prior to the patent date and that will prove it was not an unique idea. I know of one that was a 50 gallon that the case failed and soaked the floor at the LAN party. I was one of the original members of RIGG, Recreation Intel Gamers Group, that ran the LAN for PAX on behalf of Intel. I would gladly give testimony to support this if you decide to fight.

I'm only casually interested in these topics, and not an expert, but I found some interesting references -
Wikipedia claims this form of cooling has existed since the beginning of the 1900s, and lists a couple computers built in in the 90s with liquid immersion.

Also, some dude in Germany was building an oil immersed computer in 2005:

Very nice concept. I suspect I'll definitely make a go at a DIY version at some point. In the meantime, could one use that massive 3 x 3 radiator in a standard water cooled setup? I would love to silence a workstation that gets rather loud under load. Where can I find such a large radiator?

Posted on 2017-02-12 19:09:56

We did use massive 3x3 radiators mounted on the side of some of our liquid cooled systems back when we offered that type of cooling. It required a lot of chassis modification, and was heavy and hard to ship safely, but it worked in some situations. I don't remember what brand we used, but Performance PCs lists several: http://www.performance-pcs....

Though I am not a lawyer, you have very clearly documented on this website that you have done all your own research into immersion oil cooling of PCs. Therefore there is no question, legally speaking, that no patent has been infringed. Your easiest defense against this claim is that the company in question has failed the standard of patentability, because their claims of infringement derive from techniques which were obvious to you. This is probably a patent trolling company that is shooting in the dark hoping to collect money they do not deserve, and the fact that you have been intimidated into shutting down commercial production rather than risk being sued by them is, itself, grounds for a lawsuit. You can theoretically recover lost (projected) sales starting from when they first contacted you, if it can be demonstrated that their original infringement claim cannot possibly have merit, and was meant to intimidate you out of the market. Again, I am not a laywer, but you ought to confer with one.

Now that Maslow's law has really started hitting the processors industry, it would be great to have one of these kits. I like how the case was thicker than an aquarium which made it more tolerant. I understand that you cannot sell these kits for profit and that you gave away the inventory. But if you can.... PLEASE send me the CAD files or upload them for FREE.

I don't believe that developers and enthusiasts should have to pay for PATTON TROLLS. So please.... OPEN SOURCE IT!

This is clearly patent abuse, and a bit sickening. The broad claims used (eg. Claim 9 US Patent 7403392) are bogus and the patent should never have been granted. I'm not a lawyer but I did have a course on this. A basic criterion of patentability is that for something to be a valid patent claim it must represent a non-obvious improvement over the state of the art. The state of the art comprises everything that was ever publicly described anywhere (including forums) at the patent filing date. An obvious improvement is any improvement that a competent engineer familiar with the prior art can immediately think of (like adding a radiator). Prior art for claim 9 from 2005 is http://hackaday.com/2005/05..., and the differences between that (=just stick computer in oil bath) and the patent claim, are obvious enhancements, like adding a radiator. I'm sure you can find better prior art on casemodding forums. There IS a lot of engineering work in making the system be professional and safe (kudos for documenting that here with timestamps!), and LC Solutions could've patented the specifics of that, but then it would not have covered Puget's design.

What that company did was to realize that oil immersion is actually an economically viable cooling technology, not just a crass thing you can do to impress people. If you think about it, watercooling is a quite established market. Immersion cooling, done right (walls don't dissolve, proper mountings, radiator, removable cooling material), is better than watercooling in every way. Most importantly it's universally compatible, you don't need different heat sinks for different kinds of computer part. Watercooling is expensive for mainly that reason.

So LC appropriated the concept for themselves by filing a patent. They're not even the only oil cooling company, there are several others, its just that they all sell to datacenters.

What should be done is a small crowdfunding campaign to pay a lawyer to have the patent invalidated. You could give out cases as contributor perks (conditional on winning). You wouldn't need to attend or even be a party to the lawsuit, there
just needs to be some company that would actually sell the thing or there is no point. For the kickstarter, it'd only take a link to this story, one independent legal assessment, and links to prior art. It's not your main line of business, sure, but why not?

It doesnt look like puget is paying attention to this anymore unless I missed a post from them. In the mean time unless they decide to get back on the bandwagon we should work together in tracking down one of these, and ask the owner to allow it to be taken apart and scanned into cad and made available for download. Id love to give this beast a chance to procreate, instead of being put down by the patent trolls. If they cant / dont want to sell kits then they could atleast give us the cad info and pass the torch so to speak. As a pc enthusiast if I made something awesome but couldnt make money on it or take care of the project anymore, like make improvements such as making pc cables and parts that wont disolve in oil, id atleast make it available for others to continue the work that I started and if they try to make money off of it then all I would ask is that I be given credit as the creator of the original system. Like....(This system has been modified and improved by "your name" using technology by "my name")

Man, it sucks that this never got fixed, that's super lame that those damn patent trolls got their way.

Have you considered making the files for laser cutting available? Or maybe there's some sort of other update?

These are the guys that hold the patent now. The inventors are members of this company.

Sell Separate parts, not a kit

Just sell the PC Tray, empty liquid cooler, and the Aquariums separate.
Nobody has a patent on BOXES.
people can follow the videos and figure out how to put a Tray in Aquarium themselves, and hook up hoses
for their fans.

No patent on individual parts, and MAKERS can figure out the details.

Posted on 2017-10-21 13:09:26

so sorry to hear, i'vw been following you guys for at least a couple of years, and recently knew you discontinued this project because of this patent problem.
Hope you end up doing something different and equally engaging!

Will be the mineral oil be used as a coolant in watercooling pc?

///S. Khan


I wanted to ask that instead of immersing a CPU I would be immersing an S9 ANTMINER.... It produces a lot of heat @ 1600W power consumption.....

I was thinking of making a SS Steel container twice the volume of S9 Antminer and submersing the S9 into it and keeping those in a FREEZER..... (a typical home Wall Standing Freezer)...

so will it work or I would have to install a radiator to cool down the Mineral Oil...... or I can use both to cool the mineral oil down. The S9 are very sensitive to rising temperatures and their Chips get burned easily...

please help me in building this... your advise would be greatly appreciated.... If done successfully I would be sharing all the pictures and temperature values getting....

Thank you

S9 Antminer x 2

I know this is a very old page but by chance if anyone is still watching from Puget, what do you used between the CPS and or GPU and its heat sink in place of the thermal paste?

Looking into building something like this soon, but can't figure out where to get the right kind of pumps to make a large radiator with fans. All the ones I see are built onto their own radiators and too weak. I want a decent but of flow.

It seems like large scale players in this space (GRC for one) custom fab their enclosures--presumably out of aluminum or steel. On a smaller scale, I get why you guys started with acrylic fishtanks but it seems like all the enclosures you used in your experiments and kits are one piece acrylic tanks of relatively small capacity. Curious if you ever tried anything larger that involved bonded acrylic or glass panels? I'm simply curious as to whether mineral oil will deteriorate the adhesives/sealants used in those applications. My suspicion is epoxies used for acrylic tanks will do fine but the more "rubber-y" adhesives and sealants in glass tanks probably make them a no go. I'm sure testing will bear this out but trying to do a bit of googling to short cut to an answer while deep in the grips of jet lag.

Thanks for keeping these pages up for the community despite the previous legal mess!

Glass tanks use 100% silicone, not rubber. If Silicone is Mineral oil safe, then we're good.

T S the Deplorable

What is most frustrating as I consider using mineral oil to cool my Antminers is that none of the videos I have found give before and after stats on chip temperature and safely attainable hash rates. I am pricing out building a system and it will be around $400, but I don't want to spend that kind of money if it's not going to at least significantly cool my boards for the sake of longevity. If anyone has a link to a video that shows the differences in cooling and performance from mineral oil cooling, I'd appreciate it.

Posted on 2018-04-26 01:30:32

If the above statement is true , May you give back to the enthusiast community ,at least some of the "How to" & "Know how"

with your impressions and experience? and by the way , you can come back to this times more by doing so, if you make "presentation models", with example schematics and sell the parts separately , so the user community will be the maker of the end product (+ fair warnings you gave before for damages and liability ) and give back the projects and impressions to advance the implementations possible from day to day
Just got here for know how , so in future will have fun building my own from scratch.

Good afternoon everybody! I need some help. I'm planning to build a Mineral Oil Cooled PC and I'm not sure what type of cables to use and not use for my computer. I haven't bought any of the PC components yet, but I'd like to know if it would be safe to use the cables that come with it, such as the power supplier cable for the Power Supply and so on. I know mineral oil loves to munch on rubber, which is why I mentioned the previous sentence. I want to be able to immediately tell if a certain cable shouldn't be submerged, but I sadly have little knowledge about cables vs. mineral oil. Can someone please explain to me what kinds of cables can and can't be submerged & how to find out what material a certain cable is?

I apologize for any confusion I've caused and I thank you very much for reading my comment!

Is this the patent in question? https://patents.google.com/...

If so, it should expire in 2028-07-22 I think

Would it be possible to "print" the case? If you are not after profits you could open source the stl/obj file and provide a patreon / donation system. Sad to see that i am too late to the party, i am very interested in a solution like this.

Just found out about your tanks from LTT. Since you were laser cutting your own parts, are those files perhaps available somewhere? Love the concept.

Posted on 2020-08-23 20:57:41

I have a quick mineral oil question. I know on the site it says that it's not for overclocking due to heat but what if one were to rig up an AC unit to cool the oil? I can imagine tubes of AC cooled (Externally) water circulating through the mineral oil. Do you think something like that would work? Thanks.

Posted on 2020-09-07 20:34:20

you would have a severe condensation issue that you would have to adress, but yes. It would work as designed.

Posted on 2021-01-30 06:04:43

We did some testing using an industrial chiller, and condensation was a big issue. If you submerge the entire system (IO connectors and all), however, then it shouldn't matter. Zero contact with the air means no chance for condensation to form on the electronics.

The bigger problem was actually that the mineral oil gets really thick as it gets colder. Getting enough of a cooling improvement to make overclocking better than standard liquid cooling made the oil way too hard to pump. If you really wanted to push things and not get into liquid nitrogen level of things (or whatever those extreme overclockers use), you probably would do something like mineral oil cooling for the motherboard and other components, but use a standard liquid cooler setup on the CPU and GPU (possible running that through a chiller).

That way, you get the coldest possible temps on the CPU/GPU, while everything else is kept reasonable by the mineral oil. Added benefit there is that you don't have to worry about condensation on the CPU/GPU from the chilled liquid cooling since that is submerged in oil!

But really, I wouldn't do any of that. Submersion cooling looks cool, but man is it a pain to deal with.

Posted on 2021-01-30 06:03:51

I hope the patent is running out soon and you can resume these sales!
In the meantime, the pump on my submerged PC (purchased from you guys seven years ago) has started to sound like it might not last much longer--not bad for seven years of consistent performance.
I didn't see any pumps on your 'recommended peripherals' page. Do you have a recommended replacement?
