9. Install the heatsink:
CAUTION: CAUTION:
The heatsink fan does not have a fan guard. Special attention is needed when removing or installing the heatsink to
prevent finger injury.
CAUTION: CAUTION:
To prevent mechanical damage or depositing oil on your hands or other contaminant to the heatsink contact
surface, hold the heatsink only by the edge of its base plate. Do not touch the heatsink fins.
CAUTION: CAUTION:
To prevent thermal failure or component damage, do not move the heatsink once the bottom of its base plate
touches the top of the processor. Excessive heatsink movement can cause the thermal grease to smear and become
uneven. Voids in the compound can adversely impact the transfer of heat away from the processor.
CAUTION: CAUTION:
Heatsink screws must be tightened and loosened in alternating sequence. Do not overtighten the screws as this
might damage the system board or the processor socket.
a. Position the heatsink on top of the processor, ensuring that it is properly seated before securing the screws (callout 1).
b. Tighten one pair of diagonally opposite screws halfway, and then tighten the other pair of screws (callout 2 and 3).
When using a torque screwdriver, apply 0.68 N⋅m (6.0 lbf-in) of torque to completely tighten the screws.
c. Connect the heatsink fan cable (callout 4).
