Noctua NH-L12S | Installation Manual | LGA115x
LGA115x
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.
Step 5
Fan setup
Step 7
Connect the fan to the motherboard’s CPU fan header.
Depending on your CPU and the temperature inside the case, you
may interconnect the supplied NA-RC7 Low-Noise Adapter (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 motherboard 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.
Caution: Gently tighten the screws until they stop, but don’t use
excessive force (max. torque 0.6 Nm).
Caution: Applying too much thermal paste will lower heat
conductivity and cooling performance!
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-L12S, please
don’t hesitate to contact our support team ([email protected]).

Fastening the heatsink to the CPU
Caution: Please first take off the protection cover at the bottom
side of the heatsink.
Then put the heatsink onto the CPU and screw it to the screw
threads of the mounting bars. Note that you can reach through
the blades of the fan using the supplied screw driver. There is
thus no need to take off the fan for installation.
