product. Enjoy your NH-L9!
Yours sincerely,

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. 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]. Noctua cannot be held responsible for any
damage or losses caused by compatibility issues.

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.
Caution: Applying too much thermal paste will lower the heat
conductivity and cooling performance!
Step 2
Fastening the heatsink to the CPU
Caution: Tighten the screws until they stop, but don’t use
excessive force.
Caution: Please take off the white protective film at the bottom
side of the heatsink.
Then put the heatsink onto the CPU and the supplied NM-AMB2
backplate to the rear side of the mainboard. Now stick the mount-
ing screws through the holes of the backplate and fix the cooler.
Step 3
Even with high-grade products and strict quality control, the
possibility of defects cannot be eliminated entirely. Therefore,
we aim at providing the highest possible level of reliability and
convenience by offering a warranty period of 6 years and direct,
fast and straightforward RMA service.
Should you encounter any problems with your NH-L9, please don’t

Warranty, Support and FAQs
Connect the fan to the mainboard.
Depending on your CPU and the temperature inside the case,
you may interconnect the supplied NA-RC7 Low-Noise Adaptor
(L.N.A.) in order to further reduce the fan’s 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 cool-
ing performance is insufficient, please increase case ventilation or
remove the L.N.A.
In case you would like to use a 92x25mm fan for further improved
performance, please first unscrew the preinstalled NF-A9x14 fan
and use the supplied longer screws to install the 92x25mm fan.
