Noctua NH-L9i | Installation Manual | LGA115x
Dear customer,
Congratulations on choosing the Noctua NH-L9.
This small cooler packs all essential technologies of our award-winning high-
end models into a highly compact package in order to give you the best
possible quiet cooling experience for HTPC and small form factor builds. I’m
confident that you will be able to sense some of the research, attention, and
care we’ve put into making this product. Enjoy your NH-L9!
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 support@noctua.at. Noctua cannot be held responsible for any damage or losses caused by compatibility issues.

Required mounting parts:
4x NM-IBT4 Mounting-Screw
Step 1 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 center of the heat spreader.
Caution: Applying too much thermal paste will lower the heat conductivity and cooling performance!
Step 2 Fastening the heatsink to the CPU
Caution : Please first remove the white protective film at the bottom
side of the heatsink.
Then put the heatsink onto the CPU and fix it from the rear side of the
motherboard using the mounting screws.

**3.**
Caution: Tighten the screws until they stop, but don’t use excessive force.
Step 3 Fan Setup
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 cooling 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.
