Warranty, Support and FAQs
Caution: Tighten the screws until they stop.
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.
Step 3
Connect the fan to the mainboard’s CPU fan header. Depending
on your CPU and the temperature inside the case, you may
interconnect the supplied NA-RC7 Low-Noise Adaptors (L.N.A.)
in order to further reduce the fans’ 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 mainboard 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.
