Dear customer,

Congratulations on choosing the Noctua NH-D9 DX-3647 4U.

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

mance quiet cooling solutions for Intel Xeon CPUs and the latest

DX-3647 revision supports LGA3647 (both Square and Narrow ILM)

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-D9 DX-3647 4U!

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 consult the compatibility list

on our website (www.noctua.at/compatibility) and verify that the

cooler is fully compatible with your motherboard. Please also make

sure that your PC case offers sufficient clearance for the cooler and

that there are no compatibility issues with any other components

(e.g. tall RAM modules). Double check that the heatsink and fan

clips do not make contact with the VGA card or other PCIe cards.

Noctua cannot be held responsible for any damage or losses caused

by compatibility issues.

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.

Installation Manual | LGA3647

LGA3647

Take the fans off the cooler. Use the included mounting tool and

the short screws to install the appropriate brackets to the cooler.

Required mounting parts:

Determining the socket type (square vs narrow)

and selecting the appropriate brackets

Please first check if your motherboard uses square or narrow type

socket(s):

Select the NM-XFB6 brackets for square type sockets and the

NM-XFB7 brackets for narrow type sockets.

This manual shows the installation procedure on square type

sockets, but the procedure is identical on narrow type platforms.

Caution: Gently tighten the screws until they stop, but don’t use

excessive force (max. torque xx Nm).

The LGA3647 platform uses a plastic clip that fixes the CPU to the

heatsink and ensures that it is properly inserted into the socket.

There are different clips for square and narrow type sockets. Please

first select the clip that matches your socket type.

6 Installing the heatsink to the socket

Start fastening the heatsink to the socket by tightening the outer

screws (number 1 & 2), starting with the screw at pin 1.

Then tighten the two center screws (number 3 & 4), starting with

the screw that is on the opposite side of pin 1:

Caution: Gently tighten the screws until they stop, but don’t use

excessive force (max. torque xx Nm).

Remove the plastic dust cover from the CPU socket and put the

heatsink and CPU assembly onto the socket, aligning the CPU’s pin

1 indicator with the pin 1 indicator of the socket.

Verify that all the latches have snapped to the mounting brackets

and that the CPU and clip are fully attached to the heatsink.

Turn the heatsink upside down so that the base is facing upwards.

Carefully put it down onto the tips of the heatpipes and secure

it with your hand so that it cannot tilt and that the fins cannot

get bent. Remove the plastic protection cover from the base of the

heatsink and be careful not to damage the layer of pre-applied

thermal compound.

Caution: If you are not using the heatsink for the first time and

it therefore doesn’t have a fresh layer of pre-applied thermal

compound anymore, you need to apply a thin layer of thermal

compound to the CPU yourself before clipping it to the heatsink.

If there are residual traces of previous thermal paste or thermal

pads on your CPU or on the heatsink, please clean them off first.

Put the processor clip and CPU assembly onto the heatsink’s base

so that the posts of the clip go through the holes of the heatsink’s

mounting brackets. Push the clip towards the heatsink base until

the latches snap to the mounting brackets.

Caution: Some LGA3647 CPUs have a so called OmniPath fabric

connector. If your CPU is of this type, you need a different processor

clip. Please contact support@noctua.at if you have a CPU with

OmniPath fabric connector.

Orient the CPU so that the heatspreader is facing downwards and

the golden contacts are facing upwards. Be careful not to touch the

contacts. Then put the CPU into the clip, align the CPU’s pin 1

(golden triangle indicator) with the triangle pin 1 indicator of the

clip. Snap the CPU into the clip. Note that you may need to flex the

clip a bit for it to latch onto the CPU. Verify that the clip is fully

attached to the CPU before proceeding.

Put the clip upside down so that the long heatsink latches and posts

for heatsink alignment are facing downwards.
