Dear customer,

Our DX line of coolers has become a default choice in high

performance quiet cooling solutions for Intel Xeon CPUs and the

latest i4 revision supports LGA2011 (both Square and Narrow

ILM), LGA1356 and LGA1366 based Xeon platforms. Each Noctua

product is double checked for flawless operation by our quality

control team before it leaves the factory and I’m confident that

you will be able to sense some of the research, attention and care

we’ve put into making this product.

Enjoy your NH-D9DX i4 3U!

Yours sincerely,

Roland Mossig, Noctua CEO

Installation Manual

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.

If your mainboard uses a Square-ILM, please continue as

described below. If your mainboard uses a Narrow-ILM, please

refer to section LGA2011 Narrow-ILM.

LGA2011

Warranty, Support and FAQs

Even with high-grade products and strict quality control, the

convenience by offering a warranty period of 6 years and direct,

fast and straightforward RMA service.

Attaching the fan

Reattach the fan using the steel clips:

LGA2011 Square-ILM

Applying thermal paste

If there are residual traces of thermal paste or thermal pads on

your CPU, please clean them off first. Then press a small drop

(4-5mm diameter) of NT-H1 onto the centre of the heatspreader.

Fastening the heatsink to the CPU

Caution: Please first take off the fan as well as the protection cover

at the bottom side of the heatsink.

Then put the heatsink onto the CPU and tighten the four

spring-loaded screws until they stop using the supplied

screwdriver.

Caution: Tighten the screws until they stop.

Caution: Applying too much thermal paste will lower heat

conductivity and cooling performance!

Connect the fan to the mainboard’s CPU fan header. Depending

on your CPU and the temperature inside the case, you may

interconnect the supplied NA-RC7 Low-Noise Adapter (L.N.A.) in

order to further reduce the fan’s operating noise.

Caution: When using the L.N.A., check the temperature of your

CPU using appropriate software (e.g. the respective applications

of your mainboard manufacturer), in order to evade automatic

throttling of the CPU due to the increased temperature. If the

cooling performance is insufficient, please increase case

ventilation or remove the L.N.A.
