With the NH-U9DX i4, Noctua is bringing their expertise in quiet CPU cooling to the world of Intel's Xeon E5 server / workstation processors. Traditionally there have been very few low-noise cooling options for the Xeon platform, as noise level is not typically a concern for such systems. When a server or high-end workstation needs to be operating in an office or other quiet environment, though, the Noctua NH-U9DX i4 is a good choice - and it is short enough to fit in some 4U rackmount cases as well.
