Caution:
We do not recommend removing the CPU or the heatsink. If you do need
to remove the heatsink, please follow the instructions below to prevent damage to
the CPU or the CPU socket.
1. Unplug the power cord from the power supply.
2. Unscrew and remove the heatsink screws in the opposite sequence shown in
the picture above.
3. Hold the heatsink and gently wriggle it to loosen it from the CPU. (Do not use
excessive force!)
4. Once the heatsink is loosened, remove it from the CPU.
5. Clean the surface of the CPU and the heatsink to get rid of the old thermal
grease. Reapply the proper amount of thermal grease before re-installing the
heatsink.

Installing a CPU Heatsink
1. Place the heatsink on top of the CPU so that the four mounting holes are aligned
with those on the retention mechanism.
2. Screw in two diagonal screws (i.e. the #1 and the #2 screws) until just snug (do
not over-tighten the screws, which may damage the CPU.)
3. Finish the installation by fully tightening all four screws.
