Noctua NH-D9DX i4 3U 92mm Intel Xeon CPU Cooler

Noctua's DX line of coolers has become a default choice in high performance quiet cooling solutions for Intel Xeon CPUs. The i4 revision supports LGA2011 (both Square ILM and Narrow ILM); LGA1356 and LGA1366 based Xeon platforms and the new D9 model provides better performance and better compatibility than previous 9cm versions: Thanks to its 95x95mm footprint and reduced 110mm height; the NH-D9DX i4 is fully 3U compliant and clears the RAM slots on LGA2011 Square ILM and LGA13xx. At the same time; the dual tower design and the new NF-A9 PWM guarantee further improved quiet cooling performance. Fitted with the professional SecuFirm2 mounting system and bundled with Noctua's industrial-grade NT-H1 thermal compound; the NH-D9DX i4 3U forms a complete premium quality package for quietly cooling Xeon based workstations and servers.

3U compatibility The NH-D9DX i4 stands only 110mm tall. This is 15mm less than previous 4U compliant 9cm DX-line coolers and allows the NH-D9DX i4 to also fit 3U cases - ideal for noise-sensitive 3U applications in fields such as audio or video processing!
100% RAM compatibility With its 95x95mm footprint; the NH-D9DX i4 does not overhang the RAM slots on LGA2011 Square ILM; LGA1366 and LGA1356. This gives the user full access to the memory modules and guarantees 100% compatibility with tall heatspreaders or optional memory fans.
NF-A9 premium fan The highly optimised NF-A9 premium fan features Noctua's proprietary AAO frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels; which allows it to further improve the renowned efficiency of Noctua's previous 92mm models and contributes to the NH-D9DX i4's superior cooling performance.
PWM support and Low-Noise Adaptor The NF-A9 92mm fan supplied with the NH-D9DX i4 is PWM for convenient automatic speed control through the mainboard. In addition; the maximum fan speed can be reduced from 2000 to 1550rpm using the supplied Low-Noise Adaptor for even quieter operation.
Dual fan ready The NH-D9DX i4 includes an extra set of fan mounting clips for users who want to achieve even better cooling performance by adding a second; optional NF-A9 to the front fin stack. Using the y-cable supplied with the NF-A9 PWM retail fan; both fans can be connected to one CPU fan header.
PLEASE NOTE: The optional front fan will sit above the RAM and depending on the height of the RAM modules; the fan may have to be moved up so far that the total height of the cooler exceeds 110mm. As a result; the cooler may no longer fit some 3U cases. In order to guarantee full 3U compatibility in dual fan mode; please use low profile memory with up to 22mm height.
