from the top of the microprocessor and is going to be reused or when debris is
found in the grease.
When you are installing the fan sink on the same microprocessor that is was
removed from, make sure that:
v The thermal grease on the fan sink and microprocessor is not contaminated.
v Additional thermal grease is not added to the existing thermal grease on the fan
sink and microprocessor.
