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.

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-U9DX i4!

Yours sincerely,

Roland Mossig, Noctua CEO

This manual will guide you through the installation process

of the SecuFirm2™ mounting system step by step. Prior to

installing the cooler, please verify that the cooler is fully

compatible with your motherboard.

Should you encounter any difficulties, please check

the FAQs on our website (www.noctua.at/faqs)

and don’t hesitate to contact our support team at

support@noctua.at. Noctua cannot be held responsible for any

damage or losses caused by compatibility issues.

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.

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.

Warranty, Support and FAQs

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

possibility of defects cannot be eliminated entirely. Therefore,

we aim at providing the highest possible level of reliability and

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

fast and straightforward RMA service.

Should you encounter any problems with your Noctua cooler,

please don’t hesitate to contact our support team (support@

noctua.at).

Attaching the fans

Re-attach the fans to the heatsink using the steel clips:

Caution: Applying too much thermal paste will lower heat

conductivity and cooling performance!

Connect the fans to the mainboard’s CPU fan header. Note that

you can use the supplied y-cable (NA-YC1) to connect both fans

to one CPU header.

Depending on your CPU and the temperature inside the case,

you may interconnect the supplied NA-RC7 Low-Noise Adapters

(L.N.A.) in order to further reduce the fans’ operating noise.

Caution: Please use one adaptor per fan when running two fans

with adaptors. Never use one adaptor for two fans by putting it

before the y-cable.

Please make sure that both fans are aligned in the same

direction.

Caution: When using the L.N.A.s, 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 cool-

ing performance is insufficient, please increase case ventilation or

remove the L.N.A.s.

Required mounting parts:

NM-XFB4 Standard Mounting Bar

LGA2011 Narrow-ILM

NM-XFB5 90° Mounting Bar

The LGA2011 Narrow-ILM uses a different hole spacing than

Square-ILM, so please replace the pre-installed Square-ILM

mounting brackets (NM-XFB3) with Narrow-ILM brackets

(NM-XFB4 or NM-XFB5) as described below.

This manual will guide you through the installation process step

by step using the NM-XFB5 bracket as an example. Please note

that the installation procedure is identical for NM-XFB5 and

NM-XFB4.

First choose the appropriate set of Narrow-ILM mounting brackets

according to the desired orientation of the cooler:

Installation Manual

Unscrew the preinstalled LGA2011 Square-ILM mounting brackets

(NM-XFB3) and take them off the heatsink.

Then proceed with the steps described in section LGA2011

Square-ILM.

After you’ve fixed the springs and screws to the appropriate

Narrow-ILM fastening brackets, please screw the brackets to the

heatsink:

NM-XFB4

Then remove the plastic lock-rings, springs and screws from the

Square-ILM mounting brackets and put them into the Narrow-ILM

mounting brackets.

NM-XFB3

NM-XFB4/NM-XFB5

LGA1356/1366 uses a different thread than the pre-installed

screws for LGA2011 (NM-XBT1), so please change the screws as

described below.

Remove the plastic lock-rings, springs and screws (NM-XBT1)

from the mounting brackets.

Required mounting parts:

LGA1356/1366

NM-XBT2 Screws (black)

NM-XBT1 (silver)

After you’ve fixed the springs and screws to the mounting

brackets, please proceed with the steps described in section

LGA2011 Square-ILM.

Then use the springs and the lock-rings to fix the black

LGA1356/1366 screws (NM-XBT2) to the mounting brackets.
