attached to the processor. This ensures that the surface of the die is clean.

over the lugs on the back plate pins so that the base is directly over the processor
die. Turn the heat sink clockwise until it contacts the die. Then turn the heat sink ¼
turn to tighten it. The heat sink should be snug but not tight.
Caution: Overtightening the heat sink could cause excessive pressure on the die and damage
the processor.
