Dear customer,

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.

Removing the motherboard

In case you want to use the cooler on an assembled system and

your case doesn’t have a cut-out at the rear side of the mother-

board

tray, you first have to remove the motherboard from the case in

order to be able to install the supplied backplate.

Step 1

2x NM-IMB3 mounting bars1x NM-IBP2 backplate

4x NM-ITS1 thumb screws4x NM-IPS1 spacers

Place the backplate on the rear side of the motherboard so that

the

bolts stick through the mounting holes.

Caution: Please make sure that the three cut-outs in the

supplied backplate align with the screws of the motherboard’s

stock

backplate.

Installing the mounting bars

Caution: Choose the alignment of the mounting bars according to

the desired final orientation of the cooler:

Step 3

First put the plastic spacers onto the bolts of the backplate, then

add the mounting bars.

Attaching the backplate

Caution: The supplied backplate will install over the motherboard’s

stock backplate, so the motherboard’s stock backplate must not be

taken off.

Caution: Make sure that the curved sides of the mounting bars are

pointing outwards.

Fix the mounting bars using the 4 thumb screws.

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

excessive force (max. torque 0.6 Nm).

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.
