Noctua NH-U14S TR4-SP3 User Manual

Required mounting parts:
Dear customer,
Congratulations on choosing the Noctua NH-U14S TR4-SP3.
Continuing the legacy of Noctua’s classic NH-U-series, which has
received more than a thousand awards and recommendations from
international hardware websites and magazines, the NH-U14S has
become a benchmark for high-end 140mm single tower coolers.
The TR4-SP3 version is a tailored custom model for AMD’s TR4/SP3
platform and features a larger contact surface as well as the latest
SecuFirm2™ mounting system for socket TR4/SP3.
Enjoy your NH-U14S TR4-SP3!
Yours sincerely,
Roland Mossig, Noctua CEO
This manual will guide you through the installation process of the
SecuFirm2™ mounting system step by step.
Prior to installing the cooler, please consult the compatibility list
on our website (www.noctua.at/compatibility) and verify that
the cooler is fully compatible with your motherboard.
Please also make sure that your PC case offers sufficient clear-
ance for the cooler and that there are no compatibility issues
with any other components (e.g. tall RAM modules). Double
check that the heatsink and fan clips do not make contact with
the VGA card or other PCIe cards.
Noctua cannot be held responsible for any damage or losses
caused by compatibility issues.
Should you encounter any difficulties, please check the FAQs on
our website (www.noctua.at/faqs) and don’t hesitate to contact
our support team at support@noctua.at.

Offsetting the cooler to increase PCIe clearance
If you would like to use a PCIe card in the top slot and the slot is
located close to the CPU socket on your motherboard, test fit the
cooler to the CPU socket in order to check if it comes too close
to the back side of the card or overhangs the slot. If yes, you
can offset the cooler towards the top side of the motherboard by
either 3mm or 6mm for increased PCIe clearance.

In order to offset the cooler, please unscrew the NM-AFB7 fasten-
ing brackets and re-install them in the +3 (3mm offset) or +6
(6mm offset) position.
Caution: Gently tighten the screws until they stop, but don’t use
excessive force (max. torque 0.6 Nm).
