3.3.6 Installing the Heat Sink
1. If this is a new heat sink (not the one you removed above), remove the protective film, if present, on
the Thermal Interface Material (TIM) located on the bottom of the heat sink (Figure 22, “A”).
2. Set the heat sink over the processor, lining up the four captive screws with the four posts surrounding
the processor. Align the heat sink fins to the front and back of the chassis for correct airflow (front to
back). Use caution and make sure that no cables are pinched beneath the heat sink.
3. Loosely screw in the captive screws on the heat sink corners and then tighten one, then the one
diagonally opposite, and so on until each one is firmly tightened (“B”).
CAUTION: the torque spec for these screws is 8 inch pounds. Be careful not to exceed it.
