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.
a. When using a torque wrench to tighten the heatsink screws, set a torque between 1.24 N-m (11 lbf-in) to 1.47 N-m (13 lbf-in) .
