Noctua NH-L9x65 SE-AM4 Installation Manual
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.

Required mounting parts:
Removing the stock retention module
First remove the motherboard’s stock CPU cooler retention module 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 include a stock backplate, please contact Noctua customer support at [email protected].
Attaching the mounting bars
Choose either the short NM-AMB4 or the long NM-AMB5 mounting bars according to the desired final orientation of the cooler.
First put the NM-APS4 plastic spacers onto the screw threads of the backplate, then fix the mounting bars using the four long screws.
For the short NM-AMB4 mounting bars, make sure that the curved sides are pointing inwards. For the long NM-AMB5 mounting bars, make sure that the curved sides are pointing outwards.
Caution: Gently tighten the screws until they stop, but don’t use excessive force (max. torque 0.6 Nm).
Please note that on some motherboards, the long NM-AMB5 mounting bars may not fit due to making contact with components on the motherboard. In such cases, the cooler can be installed with the short NM-AMB4 mounting bars only.
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 the supplied NT-H1 thermal compound onto the centre of the heatspreader.
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 protection cover at the bottom side of the heatsink.
Then put the heatsink onto the CPU and screw it to the screw threads of the mounting bars. Note that you can reach through the blades of the fan using the supplied screw driver. There is thus no need to take off the fan for installation
Connect the fan to the mainboard’s CPU fan header. Depending on your CPU and the temperature inside the case, you may interconnect the supplied NA-RC7 Low-Noise Adaptors (L.N.A.) in order to further reduce the fans’ operating noise.
Caution: When using the L.N.A., check the temperature of your CPU using appropriate software (e.g. the respective applications of your mainboard manufacturer), in order to evade automatic throttling of the CPU due to the increased temperature. If the cooling performance is insufficient, please increase case ventilation or remove the L.N.A.
