Then attach the fan to the heatsink using 2 steel clips, placing it so that

it blows onto the heatsink (You can optionally use the second pair of clips

to install a second fan).

Depending on the orientation of the cooler, the fan should either blow towards

the rear side of the case or the power supply in accordance with the airflow

within the case.

Connect the fan to the mainboard, power supply or fan controller. Depending

on your CPU and the temperature inside the case, you may interconnect the

supplied Ultra-Low-Noise Adapter (U.L.N.A.) in order to further reduce the fan’s

operating noise.

Caution: When using the U.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 cooling performance is insufficient, please increase

case ventilation or remove the U.L.N.A.

Mounting hardware:

1x K8-backplate (silver-coloured, rectangular with 2 rectangular cut-outs

in the center)

4x Short Screws 2x Pressure springs

2x Standard

fastening brackets

2x 90°-

Fastening brackets

2x Long, black springscrews

In case you want to use the NH-U on an assembled system, you first have to

remove the mainboard from the case as the cooler has to be screwed together

with the backplate on the back side of the mainboard.

If your mainboard uses a retention module for CPU cooler installation, you have

to remove it first. Should you experience any difficulties, please consult your

mainboard’s manual. If your previous CPU cooler is attached using a different

mounting mechanism, please remove it according to its manual.

Removing the mainboard and retention module

Step 1:

Attaching the backplate on the back side of the mainboard

Step 2:

Place the K8 backplate on the back side of the mainboard, so that the back-

plate’s screw sockets stick out through the mainboard’s screwholes.
