Mac Pro (Early 2008) Take Apart — Processors, 3.2 GHz 92
Processors, 3.2 GHz
The Mac Pro (Early 2008 Dual 3.2 GHz) computer uses a special coating on the processor heatsink
and processor to manage the temperature in the computer. The silver-colored coating comes
applied to the underside of the heatsink and the top of the processor.
Use the following guidelines when handling the processor heatsink and/or processor:
• Wear disposable nitrile or latex gloves.
Avoid touching the silver-colored coating on the underside of the heatsink and the top of •
the processor.
Always make a visual inspection of new or existing heatsinks and processors before •
installing them in the computer. See “Processor Heatsink and Processor Visual Inspection
Instructions” in the Troubleshooting chapter for more information.
When removing or replacing the heatsink and/or processor, do not allow the heatsink to be •
separated from the processor for more than 30 minutes. The special coating on the heatsink
and processor degrades with exposure to air; more than 30 minutes exposure could result in
damage to the computer and a repeat, multi-part repair.
Tools
No tools are required for this procedure. However, you may nd a at-blade screwdriver helpful in
releasing the processor holder latch.
