Figure 38 The bottom of the heat sink
CAUTION: Never touch the bottom of the processor; any contaminant could prevent the mounting
pads from making contact with the socket.
CAUTION: Applying too much grease creates a gap between the contact surfaces, significantly
reducing the ability of the heat sink to draw out heat. Installing the heat sink with excessive grease
can also cause the grease to spread over the processor pins or the system board base, which can
cause electrical shorts that damage the system.
To install the new processor:
Insert the processor into the socket, using the key on the processor.
