Installing the fan

Step 5

Install the fan as described in the cooler manual. If you don’t have it at 
hand, you can download it at www.noctua.at/manuals.

Put the heatsink onto the CPU and screw it to the screw threads of the 
mounting bars. Please note that with some cooler models, it may be  
necessary to remove the fan(s) in order to reach the screws.

Caution: Tighten the screws until they stop.

As it is not possible to reliably calculate or control the forces that 
act upon a system during transport (e.g. in shipping), we gener-
ally recommend, for safety reasons, taking off coolers with a total 
weight of more than 700g (incl. fan). If the weight of the heatsink 
without fan is below 700g and the total weight including fan is 
above 700g, we recommend taking off the fan from the heatsink 
in order to reduce the weight below 700g. Noctua cannot be held 
responsible for any damage that may arise due to excessive stress 
during transport if you keep the heatsink installed. 

Should I take the cooler off before transporting 

my system?
