NH-U9B-AM2(+) | Installation Manual
Required mounting parts (from the AM2(+)-bag):
Attaching the backplate
Place the backplate on the back side of the mainboard,
aligning the backplate’s screw sockets with the mainboard’s
screwholes.
Put the 4 white, thin washers under the mounting bars and the
4 red, thick washers onto the mounting bars. Now screw the
mounting bars to the backplate using the small screws with
higher thread-pitch (from the AM2(+) bag).
Step 3:
Attaching the fastening brackets to the heatsink
Choose the fastening brackets according to the desired orienta-
tion of the cooler:
When using the 90° fastening brackets, first stick the spring
screws and springs into the fastening brackets. Then screw them
to the base of the heatsink tightly using 4 short screws.
Step 4:
Applying thermal paste
If there are residual traces of thermal paste or thermal pads on
your CPU, please clean them off first.
2x springscrews
with external thread
Caution: Make sure
that the bulgings of
the mounting bars
are pointing towards
the socket.
4x short screws with
higher thread pitch
Removing the mainboard and retention
module
Step 1:
In case you want to use the NH-U9B 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.

conductivity and cooling performance!
