Replacing the Heat Sink and Cooling Fan
Once the processor is installed, the heat sink-cooling fan must be installed on top of the processor. The thermal
patch on the bottom of the heat sink provides thermal bonding between the heat sink and processor. If the
thermal patch on the old heat sink is damaged, you will need to install a new heat sink (a new heat sink comes
with the thermal patch pre-applied).
1. Place the heat sink on top of the processor.
2. Hold the heat sink in place and close the latches to secure the heat sink to the bracket. Make sure the latches
engages the hooks on the heat sink bracket. See Figure 3-18 .
