Noctua NH-D9L User Manual (English)

Required mounting parts:

Dear customer,

The NH-D9L is a premium grade dual tower CPU cooler that has

been designed to provide excellent quiet cooling performance

at a height of only 110mm. Its comparably low profile (15mm

lower than classic 9cm tower coolers such as the NH-U9S)

doesn’t only guarantee full 3U compliance but also makes the

NH-D9L ideal for compact HTPC and Small Form Factor cases.

Enjoy your NH-D9L!

Yours sincerely,

Roland Mossig, Noctua CEO

Removing the mainboard

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 mainboard

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

order to be able to install the supplied backplate.

Step 1

2x NM-IMB2 Mounting Bars1x NM-IBP2 Backplate

4x NM-ITS1 Thumbscrews4x NM-IPS1 Spacers

Place the backplate on the rear side of the mainboard 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 mainboard’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 mainboard’s

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

taken off.

Step 2

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.

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.

Step 4

Caution: Applying too much thermal paste will lower heat

conductivity and cooling performance!
