Noctua NH-U12A | Installation Manual | LGA115x
LGA115x
Reattach both fans using the supplied steel clips for maximum
cooling performance. Alternatively, you can leave the rear fan off
and use it as a case fan instead.
Fan setup6
Connect the fan(s) to the motherboard’s CPU fan header(s). If
necessary, use the supplied NA-YC1 y-cable to connect both fans
to one fan header.
Depending on your CPU and the temperature inside the case,
you may interconnect the supplied NA-RC14 Low-Noise Adaptors
(L.N.A.) in order to further reduce the fans’ operating noise.
Caution: Never use one adaptor for both fans by putting it before
the y-cable.
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: Please first take off the fans as well as 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. Perform 2-3 turns on each screw,
then repeat until both are fully tightened.
Caution: Gently tighten the screws until they stop, but don’t use
excessive force (max. torque 0.6 Nm).
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-U12A, please
don’t hesitate to contact our support team ([e-mail]).

Warranty, support and FAQs
!
As it is not possible to reliably calculate or control the forces
that act upon a system during transport (e.g. in shipping), we
generally recommend, for safety reasons, taking the cooler off.
Noctua cannot be held responsible for any damage that may arise
due to excessive stress during transport if you keep the heatsink
installed.
