Dear customer,

Congratulations on choosing the Noctua NH-U14S.

The NH-U14S is the first 140mm model in Noctua’s award-winning

NH-U series. First introduced in 2005, the NH-U series has become

a standard choice for premium quality quiet CPU coolers and won

more than 400 awards and recommendations from leading interna-

tional hardware websites and magazines.

Enjoy your NH-U14S!

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 clearance 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 sup-

port team at support@noctua.at.

Caution: The supplied backplate will install over the motherboard’s

stock backplate, so the motherboard’s stock backplate must not

be taken off.

Attaching the backplate2

Place the backplate on the rear side of the motherboard so that the

bolts stick through the mounting holes.

Caution: Please make sure that the three cut-outs in the

supplied backplate align with the screws of the motherboard’s stock

backplate.

First put the plastic spacers onto the bolts of the backplate, then

add the mounting bars.

Installing the mounting bars3

Caution: Choose the alignment of the mounting bars according to the

desired final orientation of the cooler:

Orientation A Orientation B

Caution: Make sure that the curved sides of the mounting bars are

pointing outwards.

Fix the mounting bars using the 4 thumb screws.

Caution: Gently tighten the screws until they stop, but don’t use

excessive force (max. torque 0.6 Nm).

In case you want to use the cooler on an assembled system and

your case doesn’t have a cut-out at the rear side of the motherboard

tray, you first have to remove the motherboard from the case in

order to be able to install the supplied backplate.

Removing the motherboard1

If there are residual traces of thermal paste or thermal pads on your

CPU, please clean them off first. Then press a small drop (4-5mm

diameter) of NT-H1 onto the centre of the heatspreader.

Applying the thermal paste

Caution: Applying too much thermal paste will lower heat

conductivity and cooling performance!

Caution: Please first take off the fan as well as the protection cover

at the bottom side of the heatsink.

Fastening the heatsink to the CPU5

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.

Should you encounter any problems with your NH-U14S, please

don’t hesitate to contact our support team (support@noctua.at).

Please also consult the FAQ section on our website:

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 gen-

erally 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.

Transporting your system!

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.

Clip position for thick spacers:

Then put the heatsink onto the CPU and screw it to the screw

threads of the mounting bars. Perform 2-3 turns on each screw,

then repeat until both are fully tightened.

Caution: Gently tighten the screws until they stop, but don’t use

excessive force (max. torque 0.6 Nm).

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

Fan Setup6

Connect the fan to the motherboard’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 motherboard 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 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 motherboard 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.

1. Remove standard spacers on rear fan

2. Install thick spacers on rear fan
