Install the processor heat sink.
a.
Align the heat sink with the guide pins on the system board; then, lower the heat sink down
until it is firmly seated.
b.
Fully tighten the four captive screws in the installation sequence shown on the heat-sink
label. Tighten the screws until they stop; then, visually inspect to make sure that there is no
gap between the screw shoulder beneath the heat sink and the system board. (For reference,
the torque required for the captive screws to fully tighten is 1.4-1.6 newton-meters, 12-14
inch-pounds.)
