Noctua NH-U12A | Installation Manual | LGA115x
LGA115x
Caution: The supplied backplate will install over the mother-
board’s stock backplate, so the motherboard’s stock backplate
must not be taken off.
Attaching the backplate
2
Place the backplate on the rear side of the motherboard so that
the bolts stick through the mounting holes.
Caution: Please make sure that the three cut-outs in the
supplied backplate align with the screws of the motherboard’s
stock backplate.
First put the plastic spacers onto the bolts of the backplate, then
add the mounting bars.
Installing the mounting bars

Caution: Choose the alignment of the mounting bars according to
the desired final orientation of the cooler:
Caution: Make sure that the curved sides of the mounting bars are
pointing outwards.
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).
If there are residual traces of thermal paste or thermal pads on
your CPU, please clean them off first. Then press a small drop
(3-4mm diameter) of NT-H1 onto the centre of the heatspreader.
Applying the thermal paste
Caution: Applying too much thermal paste will lower heat
conductivity and cooling performance!

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
