NVIDIA RTX Graphics Card Cooling Issues

With the RTX series of GPUs, NVIDIA has moved to using dual fans as the standard cooling layout on their GeForce and Titan video cards. This is a big change from past generations and has even bigger implications for using NVIDIA graphics cards in multi-GPU workstations. Let’s look at what changed, what it impacts, and what can be done to work around it.

Custom vs. Closed Loop Liquid Cooling

As a custom computer manufacturer, we’ve sold liquid-cooled systems from well before I joined the company. A water-based coolant is able to transfer heat away from hot components like the processor (CPU) and video card (GPU) more quickly than air alone would. That added cooling is appealing for folks who want to push their systems beyond design specifications. Overclocking ability is perhaps the most the most tangible benefit of liquid-cooling, but there are other reasons some folks are interested in it: liquid-cooling can make a computer look very stylish, for example, or allow operation of more hot-running components than a chassis could normally keep cool.
