a. Position the heatsink on the processor backplate.
b. Tighten one pair of diagonally opposite screws halfway, and then tighten the other pair of screws.

CAUTION: Heatsink retaining screws should be tightened or loosened in diagonally opposite
pairs (in an "X" pattern). Do not overtighten the screws as this can damage the board, connectors,
or screws. Use the wrench supplied with the system to reduce the possibility of overtightening the
screws.
