Noctua NH-U12S - Manual (Page 2)

Even with high-grade products and strict quality control, the pos-
sibility of defects cannot be eliminated entirely. Therefore, we aim
at providing the highest possible level of reliability and conveni-
ence by offering a warranty period of 6 years and direct, fast and
straightforward RMA service.
Should you encounter any problems with your NH-U12S, please
don’t hesitate to contact our support team ([email protected]).

Warranty, Support and FAQs
Then put the heatsink onto the CPU and screw it to the screw
threads of the mounting bars. Connect the fan to the mainboard’s CPU fan header.
Depending on your CPU and the temperature inside the case, you
may interconnect the supplied NA-RC6 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 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.
Caution: Tighten the screws until they stop.
Reattach the fan to the heatsink using the supplied steel clips:

Step 6 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 mainboard fan header.
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.
