Take the fans off the cooler.

Dear customer,

Thank you very much for choosing the Noctua NH-U12S DX-4677.

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-U12S DX-4677!

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.

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, 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 support@noctua.at.

When 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.

INSTALLATION MANUAL

Required mounting parts:

Removing the fans1

Assembly of carrier frame, CPU and heatsink &

installation to the socket

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-XFB9 brackets use the same mounting parts, so the

procedure is identical for Noctua heatsinks.

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

6 Installing the fans3

Connect the fan(s) to the motherboard’s CPU fan header(s). If

necessary, use the supplied NA-YC1 y-cable to connect both

fans to one fan header.

NOCTUA MOBILE-TAG

Plastic CPU carrier frame

Please note that installing an LGA4677 processor and heatsink

requires a plastic CPU carrier frame such as the one shown

above. These carrier frames are included with boxed retail CPUs

and available separately via Intel sales partners for tray type

CPUs. As different CPUs require different carrier frame types

(E1A, E1B or E1C), please make sure to purchase the correct

carrier frame for tray type CPUs.
