6. Lift the fan sink from the processor and set it on its side to keep from contaminating the work
area with thermal grease.
CAUTION:
to evenly seat the heat sink to the processor. This is especially important as the pins on the socket
are very fragile and any damage to them may require replacing the system board.
When reinstalling an existing heat sink, make sure that its bottom has been cleaned with an alcohol
wipe and fresh thermal grease has been applied to the top of the processor. New heat sinks come
from the factory with fresh thermal grease already applied.
