96 - PowerBook G4 (17-inch) Take Apart Heatsink and Fan Assembly
Procedure
Note: The Heatsink and fans are one assembly part.
1. Remove the screws and lift out the heatsink and fan assembly.
Important: Do not attempt to transfer fans from one heat sink to another. This can create
acoustic issues.
Replacement Note: Make sure to clean existing thermal material from the logic board and
apply new thermal material (see Logic Board chapter).
Important: If a replacement heatsink comes with thermal pads installed, you will only
need to install Thermal Gel (922-5929) to the center mating surface of the heatsink.
2. Reassemble and test all ports, components and functions of the computer.
