ence by offering a warranty period of 6 years and direct, fast and
straightforward RMA service.

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-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 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.
Reattach the fan to the heatsink using the supplied steel clips:

While Noctua recommends using an NF-A15 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.
Adding a second fan
The NH-U14S includes an extra set of fan clips and an extra set of
thicker anti-vibration pads for installing a second NF-A15 fan in
push/pull mode in order to further improve cooling performance.
Please use the thicker anti-vibration pads on the rear NF-A-15 fan
for improved acoustics if space allows. The y-cable supplied with
the retail NF-A15 fan can be used to control the speed of both fans
via the same mainboard fan header.
Please note that while the NF-A15 fan included with the NH-
U14S runs at 1500rpm, Noctua recommends using the standard
1200rpm retail version as a rear fan in push/pull mode as the
combination of 1500rpm at the front and 1200rpm at the rear
will provide the best balance of performance and acoustics.
If you would like to run both fans at the same speed, please use
the supplied Low-Noise Adaptor on the front fan to reduce the
speed to 1200rpm.
