  Warranty, support and FAQs

!

As it is not possible to reliably calculate or control the forces  
that act upon a system during transport (e.g. in shipping), we 
generally 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. 

  Transporting your system

!

If there are residual traces of thermal paste or thermal pads on 
your CPU, please clean them off first. Then press a small drop with 
3-4mm diameter of NT-H1 onto the centre of the heatspreader. 

  Applying the thermal paste

Caution: Applying too much thermal paste will lower heat  
conductivity and cooling performance!

Fix the mounting bars using the four 

NM-ITS1

 

thumb screws.

Caution: Gently tighten the screws until they stop, but do not use 
excessive force (max. torque 0.6 Nm).

Caution: Make sure that the curved sides of the mounting bars are  
pointing outwards. 

Caution: If you’re using the cooler for the first time, please take 
off the protection cover at the bottom side of the heatsink first!  

Put the heatsink onto the CPU and screw it to the screw threads 
of the mounting bars.
