8 Gently lift the heat sink off of the processor and set the heat sink aside
with thermal grease side facing up.
CAUTION:
The processor is held in its socket under strong pressure. Be aware
that the release lever can spring up suddenly if not firmly grasped.

release the lever from the locked position. Rotate the lever 90 degrees
upward until the processor is released from the socket. See Figure 3-17.
