Step 1:
Removing the mainboard
In case you want to use the NH-U12P on an assembled system,
you first have to remove the mainboard from the case as the
cooler has to be screwed together with the backplate on the
back side of the mainboard.
Step 2:
Attaching the backplate
Place the backplate on the back side of the mainboard, aligning

the backplate's screw sockets with the mainboard's screw-
holes.
Caution: The rubber foam square of the LGA backplate
has to face the mainboard. Don't remove the white protec-
tion film!
Caution: Don't forget to
put 4 washers between the
mainboard and the mount-
ing bars to avoid damage to
the mainboard.
Choose the alignment of the mounting bars according to the
desired final orientation of the cooler:
Orientation A Orientation B
Caution: Make sure that the straight sides of the mounting
bars face the socket and the bulgings are pointing outwards.
Now screw the mounting bars to the backplate using small
screws and washers.
Step 3:
Attaching the fastening brackets to the heatsink
Tightly screw the fastening brackets to the base of the heatsink
using 4 short screws.
Step 4:
Applying thermal paste
If there are residual traces of thermal paste or thermal pads on
your CPU, please clean them off first.
Press a small drop (4-5mm diameter) of NT-H1 onto the cen-
tre of the heat-spreader.
Caution: Applying too much thermal paste will lower the heat
conductivity and cooling performance!
Caution: Peel off the protection film at the bottom side of the
heatsink first!
Put the heatsink onto the CPU and turn it back and forth a few
times in order to spread the paste.
