Fan setup
Step 6
Connect the fan to the motherboard’s CPU fan header.
Depending on your CPU and the temperature inside the case, you
may interconnect the supplied NA-RC7 Low-Noise Adapter (L.N.A.)
in order to further reduce the fan’s operating noise.
Caution: When using the L.N.A., check the temperature of your
CPU using appropriate software (e.g. the respective applications
of your motherboard manufacturer), in order to evade automatic
throttling of the CPU due to the increased temperature. If the cooling
performance is insufficient, please increase case ventilation or
remove the L.N.A.
Fastening the heatsink to the CPU
Caution: Please first take off the protection cover at the bottom
side of the heatsink.
Then put the heatsink onto the CPU and screw it to the screw
threads of the mounting bars. Note that you can reach through
the blades of the fan using the supplied screw driver. There is
thus no need to take off the fan for installation.

Caution: Applying too much thermal paste will lower heat conduc-
tivity and cooling performance!
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 the supplied NT-H1 thermal compound onto
the centre of the heatspreader.
Step 3
Caution: Gently tighten the screws until they stop, but don’t use
excessive force (max. torque 0.6 Nm).

For the short NM-AMB10 mounting bars, make sure that the curved
sides are pointing inwards. For the long NM-AMB11 mounting
bars, make sure that the curved sides are pointing outwards.
Fan configuration
The NH-L12S ships with the fan installed underneath the fins (low
profile mode). Alternatively, you can take off the fan and install it
on top of the fins to make more room for tall RAM or other compo-
nents (high clearance mode). Note that the NH-L12S will provide
best performance to noise efficiency in high clearance mode.
