Note
Be aware of orientation of heat sink.
10. Temporarily tighten the four screws diagonally,
then tighten them securely.
Make sure that the screw aligns with the screw
hole. If not, the screw may damage the
motherboard.
11. Make sure that the heat sink is installed on a level with the motherboard.
Note
If the heat sink is not level, remove it, and then install it again.
The following probably causes the heat sink not to be level:
– The CPU is not positioned correctly.
– All screws are not completely tightened.
Do not move the secured heat sink.
