Description 

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), LGA2066 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..

 

Noctua NH-D9DX i4 U3 Features


3U compatibility. 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. 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. 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’ superior cooling performance.

PWM support and Low-Noise Adaptor. PWM support and Low-Noise Adaptor
The NF-A9 92mm fan supplied with the NH-D9DX i4 supports 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 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.*

Dual fan ready SecuFirm2™ Mounting System
Noctua’s SecuFirm2™ mounting systems have become synonymous with quality, safety and ease of use. Supporting Intel’s LGA2011 (both Square and Narrow ILM), LGA2066, LGA1356 and LGA1366 Xeon platforms, the SecuFirm2™ mounting included with the NH-U12DX i4 guarantees perfect contact pressure and maximum convenience on all sockets.

NT-H1 Thermal Compound. NT-H1 Thermal Compound
Having received more than 100 awards and recommendations from hardware journalists around the world, Noctua’s NT-H1 is a proven professional grade TIM solution that provides minimum thermal resistance, excellent ease of use and outstanding reliability.


6 Years Warranty. 6 Years Warranty
Noctua products are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the supplied NF-A9 features an MTBF rating of more than 150.000 hours and the entire NH-D9DX i4 package comes with a full 6 years manufacturer’s warranty.


*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.

FAQ:

  1. The DX models (NH-U12DX i4, NH-U9DX i4, NH-U12DX 1366, NH-U9DX 1366) can only be used on mainboards that have a backplate with screw threads for CPU cooler installation (such as the Intel reference backplate for Xeon 5500). The cooler is thus incompatible with Xeon 3500 and Core i7 mainboards that don’t have such a backplate. Please choose our normal retail models with LGA1366 support (or NM-I3 kit) for these mainboards.
  2. There are two different types of ILM (Independent Loading Mechanism) for Intel’s LGA2011 based Xeon CPUs: Square ILM with 80x80mm hole spacing and Narrow ILM with 56x94mm hole spacing. The mounting system of the NH-U12DX i4/NH-U9DX i4 3U/NH-U9DX i4 is fully compatible with both types.
