This manual will guide you through the installation process
of the SecuFirm2™ mounting system step by step. Prior to

our website (www.noctua.at/compatibility) and verify that the
cooler is fully compatible with your motherboard. Should you
encounter any difficulties, please check the FAQs on our website
(www.noctua.at/faqs) and don’t hesitate to contact our support
team at [email protected]. Noctua cannot be held responsible

2x NM-AMB3 Mounting Bars
4x NM-APS1 Plastic Spacers 4x NM-ALS1 Screws
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.
Step 1
Caution: Make sure that the curved sides of the mounting bars are
pointing outwards.
Caution: Tighten the screws until they stop.
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.
Step3
Caution: Applying too much thermal paste will lower heat
conductivity and cooling performance!
Fastening the heatsink to the CPU
Caution: Please first take off the fan as well as the protection cover
at the bottom side of the heatsink.
Step 4
Then put the heatsink onto the CPU and screw it to the screw
threads of the mounting bars.
Caution: Tighten the screws until they stop.
