Warranty, Support and FAQs
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.

As it is not possible to reliably calculate or control the forces that
act upon a system during transport (e.g. in shipping), we gener-
ally 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.
Should I take the cooler off before transporting
my system?
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.
Adding a second fan
The NH-U14S TR4-SP3 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
TR4-SP3 runs at 1500rpm, Noctua recommends using the stand-
ard 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.
1. Remove standard pads on rear fan
2. Install thick pads on rear fan
