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].

2x NM-IMB3 mounting bars
4x NM-ITS1 thumb screws
4x NM-IBT2 bolts
Fix the mounting bars using the 4 thumb screws.
Caution: Gently tighten the screws until they stop, but don’t use
excessive force (max. torque 0.6 Nm).
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 2
Caution: Applying too much thermal paste will lower the heat
conductivity and cooling performance!

Fan configuration
The NH-L12S ships with the fan installed underneath the fins (low
profile mode). Alternatively, you can take off the fan and install it on
top of the fins to make more room for tall RAM or other components
(high clearance mode). Note that the NH-L12S will provide best
performance to noise efficiency in high clearance mode.
