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 Adaptor 
(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..

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.

Perform 2-3 turns on each screw, then repeat until both are fully 
tightened.
