board. (Two screws on the far side of the heat sink are not visible in the
following photograph.)

heatsink slightly to loosen it.
Caution
The heat sink has Thermal Interface
Material (TIM) on the bottom. Be careful
not to damage this material when you
remove the heat sink from the processor.
If removing the heat sink also pulls the
processor out of the processor socket, the
processor could be damaged.

bracket out of the way.
