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).

While Noctua recommends using an NF-F12 fan for best
results in dual fan mode, the extra set of fan clips can also
be used to install most other fans. In this case, please put the
supplied self-adhesive anti-vibration strips onto the heatsink to
avoid vibrations being transmitted to the cooler.
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-U12S

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 fan off the
heatsink in order to reduce the weight below 700g. Noctua
cannot be held responsible for any damage that may arise
due to excessive stress during transport if you keep the fan
installed.
Transporting your system
!
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-RC6 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 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 ventila-
tion or remove the L.N.A.
Adding a second fan
The NH-U12S includes an extra set of fan clips and an extra
set of thicker anti-vibration pads for installing a second NF-
F12 fan in push/pull mode in order to further improve cooling
performance.
Please use the thicker anti-vibration pads on the rear NF-F12
fan for improved acoustics if space allows.
The y-cable supplied with the retail NF-F12 fan can be used
to control the speed of both fans via the same motherboard
fan header.
