  Removing the stock retention module - 

  Putting the backplate in place

1

Please first choose the correct set of plastic spacers and the correct 
set of holes on the mounting bars depending on whether you are 
using a socket AM4 or a socket AM2(+)/AM3(+)/FM1/FM2(+) 
motherboard:

Required mounting parts:

If your motherboard comes with a pre-installed CPU cooler  
retention module, please first remove it by unscrewing it from the 
backplate. The SecuFirm2™ mounting system will install directly 
to the stock backplate, so please keep it in place.

If your motherboard does not come with a pre-installed CPU cooler 
retention module, the AMD stock backplate should be included with 
the motherboard accessories. Please put the backplate on the rear 
side of the motherboard so that the screw threads of the backplate 
stick through the mounting holes of the motherboard as shown  
below. If your motherboard does not include a stock backplate, 
please contact Noctua customer support at [email protected].

marked with “3” for AM2(+)/AM3(+)/FM1/FM2(+).

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

Prior to installing the cooler, please consult the compatibility list 
on our website (www.noctua.at/compatibility) and verify that the 
cooler is fully compatible with your motherboard. Please also make 
sure that your PC case offers sufficient clearance for the cooler and 
that there are no compatibility issues with any other components 
(e.g. tall RAM modules). Double check that the heatsink and fan 
clips do not make contact with the VGA card or other PCIe cards. 
Noctua cannot be held responsible for any damage or losses caused 
by compatibility issues. 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].
