When reinstalling the fan 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.
CAUTION: Fan sink retaining screws should be tightened in diagonally opposite pairs (as in an X) to evenly
seat the fan sink on the processor to avoid damage that could require replacing the system board.
Make sure to replace the fan duct. Failure to install the fan duct may cause the computer to overheat.
