If there are residual traces of thermal paste or thermal pads on
your CPU, please clean them off first.
Then press a small drop (4-5mm diameter) of NT-H1 onto the
centre of the heat-spreader.
Caution: Applying too much thermal paste will lower the heat
conductivity and cooling performance!
Removing the retention module
Step 1:
If your mainboard uses a retention module for CPU cooler
installation, please remove it first. The SecuFirm2tm mounting
system will install directly to your mainboard’s stock backplate
on the rear side of the socket.
