Dear customer,
Congratulations on choosing the Noctua NH-D15. Built on the

class dual tower cooler for the highest demands. I’m confident that
you will be able to sense some of the research, attention and care
we’ve put into making this cooler. Enjoy your NH-D15!

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
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.
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.
