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

Then put the heatsink onto the CPU so that the four spring-loaded
screws align with the threads of the CPU socket. Use the sup-
plied mounting tool to tighten the screws. Perform 3 turns on each
screw, then repeat until all are fully tightened.
Caution: Gently tighten the screws until they stop, but don’t use
excessive force (max. torque 0.6 Nm).
Fastening the heatsink to the CPU
Please first take off the fan as well as the protection cover at the
bottom side of the heatsink.
Step 3
Note that you can tilt the mounting tool for reaching the screws in
case they are blocked by the heatsink fins.
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.
Applying thermal paste
If there are residual traces of thermal paste or thermal pads on
your CPU, please clean them off first.
Then press 9 small drops (3-4mm diameter) of NT-H1 onto the
the heatspreader in a square 3x3 pattern as shown below:
Step 2
Caution: Applying too much thermal paste will lower heat
conductivity and cooling performance!
Continue by adding 4 larger drops (5-6mm diameter) of NT-H1 in
a square pattern at the center as shown below:
