Replacing the CPU heatsink
1. Disconnect power from the system ( Pre-disassembly procedures on page 53). Remove the access
panel (
Access panel on page 58) and the CPU heatsink (Removing the CPU heatsink
on page 86).
2. Use alcohol and a soft cloth to clean all of the thermal interface material residue from the CPU
heatsink and processor.
CAUTION Allow the alcohol on the processor and CPU heatsink to dry completely.
3. Place the CPU heatsink on top of the processor, and align the four mounting screws with the
holes (1) in the system board.
NOTE If both CPU heatsinks were removed, be sure that all system board standoffs
engage with the keyholes in the chassis, and that the system board connectors engage
correctly with the rear I/O panel, and push back on the system board while engaging the
CPU heatsink screws with the chassis standoffs. You only need to push back when trying
to engage the first screw.
