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

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

pointing outwards.

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.

Caution: Applying too much thermal paste will lower heat

conductivity and cooling performance!

Step 4

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 sup-

plied 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.

Fix the mounting bars using the 4 thumb screws.

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

excessive force.

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.
