Noctua DX Series User manual

Take the fan off the cooler.
Dear customer,
Thank you very much for choosing the Noctua NH-U14S DX-4189.
Our DX line of coolers has become a default choice in high
performance quiet cooling solutions for Intel Xeon processors,
and I’m confident that you will be able to sense some of the
research, attention and care we’ve put into making this product.
Enjoy your NH-U14S DX-4189!
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
centre on our website (ncc.noctua.at) and verify that the cooler
is fully compatible with your motherboard.
Pleasealso makesurethat your PCcaseoffers sufficientclearance for
the cooler and that there are no compatibility issues with any other
components (e.g. tall RAM modules).
Doublecheckthattheheatsinkandfanclipsdonotmakecontactwith
the VGA card, other PCIe cards, motherboard heatsinks or any other
components.
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 [e-mail] attaching the CPU carrier frame to the base of the heatsink,
turn the heatsink upside down so that the base is facing upwards.
Carefully put it down onto the tips of the heatpipes and secure
it with your hand so that it cannot tilt and that the fins cannot
get bent.
Remove the plastic protection cover from the base of the heatsink
and be careful not to damage the layer of pre-applied thermal
compound.
Caution: If you are not using the heatsink for the first time and
it therefore doesn’t have a fresh layer of pre-applied thermal
compound anymore, you need to apply a thin layer of thermal
compound to the CPU yourself before clipping it to the heatsink.
If there are residual traces of previous thermal paste or thermal
pads on your CPU or on the heatsink, please clean them off first.

plastic CPU carrier frame for
LGA4189-4 (P4)

Caution: The supplied plastic CPU carrier frame is for LGA4189-4
(P4) only. LGA4189-5 (P5) systems use the same mounting
mechanism system but require a different CPU carrier frame.
Please contact us at [email protected] if you would like to use
the cooler on a LGA4189-5 (P5) type system.
Please follow the official Intel installation manual for how to
attach the CPU carrier frame to the heatsink, insert the CPU to the
carrier frame and install the CPU/heatsink assembly to the socket:
www.intel.com/processorinstall
Note that while the Intel illustrations show a 2U heatsink, the
Noctua NM-XFB8 brackets use the same mounting parts, so the
procedure is identical for Noctua heatsinks.
Reattach the fan to the heatsink using the supplied steel clips:

Adding a second fan
The NH-U14S DX-4189 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-A15 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 motherboard fan header.
Please note that while the NF-A15 fan included with the
NH-U14S DX-4189 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.

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.

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 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.
