Installing and Removing the Heat Sink
 
6 Wait 30 seconds for the heat sink to loosen from the processor. 
7 If the heat sink has not separated from the processor, carefully rotate the heat sink in a clockwise, then 
counterclockwise, direction until it releases from the processor. Do not pry the heat sink from the 
processor.
8 Lift the heat sink off of the processor and set the heat sink on the work surface so it rests on the ends of 
the retention screws.
9 Use a clean lint-free cloth to remove any thermal grease from the surface of the processor shield.
10 Pull the socket-release lever 90 degrees upward until the processor is released from the socket. See
