In the order indicated on the heat sink, loosen the four silver captive Torx screws (1) – (4), and
then lift the heat sink out of the computer (5).
CAUTION:
Remove heat sink retaining screws in diagonally opposite pairs (as in an X) to even
the downward forces on 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.
CAUTION:
To reduce a degradation in thermal performance, be sure not to touch the thermal
grease on the surface of the processor or the heat sink.
