Noctua NH-U12P SE2 Bedienungsanleitung
NH-U12P SE2 | Installation Manual INTEL
Removing the mainboard
Step 1:
In case you want to use the cooler on an assembled system,
you first have to remove the mainboard from the case in order
to be able to install the supplied backplate.
Caution: On LGA1366 and LGA1156/1155, the supplied back-
plate will install over the mainboard’s stock backplate, so the
mainboard’s stock backplate must not be taken off.
Required mounting parts:
First put the four bolts into the holes appropriate for your
mainboard’s CPU socket.
Setting up the backplate
Step 2:
Thank you very much for choosing a Noctua cooler.
This manual will guide you through the installation process
of the SecuFirmtm 2 mounting system step by step.
Prior to installing the cooler, please consult the
compatibility list on our website and verify that the cooler
is fully compatible with your motherboard. Should you
encounter any difficulties, please check the FAQs on our
website and don’t hesitate to contact our support team at
any damage or losses caused by compatibility issues.
Multilingual versions of this manual are available
on our website: www.noctua.at
Caution: Please verify that all four bolts are put into the
appropriate holes fully pushed in.
Step 4:
Installing the mounting bars
First put the plastic spacers onto the bolts, then add the
mounting bars.

Installation Manual
4x plastic spacers 4x thumbscrews
1x 3-in-1 Intel backplate
4 bolts for backplate 2x fastening brackets
4x short screws 2x mounting bars For use on LGA1366 and LGA1156/1155 mainboards, please
remove the rubber inlay. Make sure that the rubber inlay is
in place for LGA775.
LGA1366 & LGA1156/1155 LGA775
Caution: On LGA1156/1155, please make sure that the two
cuts in the supplied backplate align with the screws of the
mainboard’s stock backplate.
Caution: Choose the alignment of the mounting bars according
to the desired final orientation of the cooler:
Orientation A
Step 3:
Attaching the backplate
Place the backplate on the rear side of the mainboard so that
the bolts stick through the mounting holes.
Caution: Make sure that the curved sides of the mounting bars
are pointing outwards.

Caution: Tighten the screws until they stop.
Caution: Make sure to use the correct holes on the mounting bars.
Fix the mounting bars using the 4 thumb screws.
Step 5:
Attaching the fastening brackets to the heatsink
Tightly screw the fastening brackets to the base of the heatsink
using the 4 short screws.
Caution: Make sure to install the fastening brackets in the
correct position:
Connect the fan(s) to the mainboard, power supply or fan con-
troller. Use the supplied y-split cable to connect both fans to
one fan header. Depending on your CPU and the temperature
inside the case, you may interconnect the supplied Low-Noise
Adapter (L.N.A.) or Ultra-Low-Noise Adapter (U.L.N.A.) in
order to further reduce the fan’s operating noise.
Caution: Please use one adaptor per fan when running two
fans with adaptors. Never use one adaptor for two fans by
putting it before the y-split cable.
Caution: When using the (U.)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 (U.)L.N.A.

Attaching the fan
Step 8:
First stick the 2 anti-vibration strips onto the cooling fins in
order to dampen minor vibrations emitted by the fan.
Then attach the fan to the heatsink using the 2 steel clips,
placing it so that it blows onto the heatsink.
Add the second NF-P12 fan sucking air off the rear side of the
heatsink for extra performance (average gains 1-3°C). Please
make sure that both fans are aligned in the same direction.
Step 6:
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
heat-spreader.
Caution: Applying too much thermal paste will lower the heat
conductivity and cooling performance!
Step 7:
Fastening the heatsink to the CPU
Caution: Please take off the protection cover at the bottom side
of the heatsink first!
Put the heatsink onto the CPU and screw it to the screw threads
of the mounting bars.
Caution: Tighten the screws until they stop.

Caution: The SecuFirmtm 2 mounting system requires a back-
plate, which is preinstalled on most AM2/AM2+/AM3 main-
boards.

Removing the retention module
Step 1:
If your mainboard uses a retention module for CPU cooler
installation, please remove it first. The SecuFirmtm 2 mounting
system will install directly to your mainboard’s stock backplate
on the rear side of the socket.
