Removal and replacement procedures 39
Figure 12 Removing the heatsink
IMPORTANT: If the heatsink has been removed for any reason on a previously installed processor, it
is critical that you clean off any residue of the old thermal compound from both the heatsink and
processor with alcohol and a clean cloth and apply more thermal interface material to the
integrated heat spreader on the processor to ensure proper thermal bonding between the processor
and the heatsink.
To remove a processor:
1. Open the processor locking lever and the processor socket retaining bracket.
