Mac Pro (8x) Troubleshooting — General Information 14 8
To remove the particles, use the suction pipette that comes with the replacement heatsink and
processor. (The pipette is also available through GSX as part of the Mac Pro Grease Kit, part
number 076-1258.) Depress the bulb end of the pipette, place the other end over the particle,
and release the bulb. The particle will be suctioned into the pipette.
Once you have removed all stray particles, place the pipette inside the resealable bag included
with the replacement part. Pack this bag along with the failed part in the box that the
replacement part came in, and return the box to Apple.
Gasket on Heatsink
Check that the gasket that surrounds the silver-colored coating on the underside of the heatsink
is in good condition, as shown below.
Replace the gasket if it shows obvious damage, such as cracks, folds, and broken-o surfaces, or
if it is dislocated from the heatsink. The gasket is available through GSX as part of the Mac Pro
Grease Kit, part number 076-1258.
