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.

Warranty, support and FAQs
Caution: Gently tighten the screws until they stop, but don’t use
excessive force (max. torque 0.6 Nm).
Fan setup
Step 5
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.
