Tools

The only tool required for this procedure is a long-handled Phillips screwdriver.

Preliminary Steps

Before you begin, open the computer, lay it on its side with the access side facing up, and remove the front inlet fan assembly.

Part Location

Procedure

1. Remove the metal G5 cap from the top of the heatsink.

Note: The cap is held in place by two sets of small plastic latches on the underside of the cap. To release the latches, place both index fingers under the edge of the cap near the "G" and press in on the first set of latches. Then release the second set of latches under the opposite edge of the cap and lift the cap off the heatsink.

3. Lift the heatsink and processor straight up out of the computer.

Warning: The heatsink and processor are a unit. Never separate the heatsink from the processor, or you will damage the processor and void the warranty.

4. Repeat steps 1-3 for the second processor, if necessary.

Replacement Note: If you are replacing the processor with a new processor, do the following:

  • When removing the new processor from its packaging, be careful to lift the processor straight up out of the box. Tilting the processor could damage the heatsink seal.
  • Before installing the processor, remove the cap over the processor connector.

Warning: Do not remove the clear plastic strip on the bottom of the processor. Removing the plastic could cause a short in the logic board.

Note: When installing the processor, place the first two screws diagonally from each other and tighten part way. Replace the other two screws and tighten part way. Then tighten all screws again until they are fully secured.

Important: Whenever you replace a processor with a new processor, you must run Apple Service Diagnostic (once the computer is reassembled). You must also run the diagnostic if you re-install the same processor but in a different connector from the one in which it was originally installed. Apple Service Diagnostic for Power Mac G5 is available as a download from the Disc Images section of the Apple Service Source website. For more information, see "Thermal Calibration" in the Troubleshooting chapter.
