Required mounting parts (from the LGA775-bag):
the backplate’s screw sockets with the mainboard’s screw-
holes.
Step 3:
Attaching the fastening brackets to the heatsink
Now screw the mounting bars to the backplate using small
screws.
Tightly screw the fastening brackets to the base of the heatsink
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.
Removing the mainboard
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.
Prior to installing the cooler, please consult the compat-
ibility list on our website and verify that the cooler is fully
compatible with your motherboard.
Should you encounter any difficulties, please check the
FAQs on our website and don’t hesitate to contact our
