Attaching the mounting bars
First put the plastic spacers onto the screw threads, then fix the
mounting bars using the 4 long screws.
Step 2
Caution: The SecuFirm2™ mounting system requires a back-
plate, which is preinstalled on most AMD mainboards. If your
mainboard doesn’t have a backplate, please contact our support
team at [email protected].
Removing the retention module
If your mainboard uses a retention module for CPU cooler instal-
lation, please remove it first. The SecuFirm2™ mounting system
will install directly to your mainboard’s stock backplate on the rear
side of the socket.

Applying thermal paste
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 heatspreader.
Step 3
Caution: Applying too much thermal paste will lower the heat
conductivity and cooling performance!
