Removal and Replacement Procedures— Microtower (MT) Chassis
6.14 Heatsink
1. Prepare the computer for disassembly (
Section 6.1, “Preparation for Disassembly”
).
2. Remove the access panel and rotate the computer so the system board is parallel to the table
to make it easier to work on (
Section 6.3, “Access Panel”
).
3. Disconnect the heatsink fan cable from the system board.
4. Disconnect the four-pin power cable from the system board to make it easier to access the
heatsink.
5. Loosen the four captive screws
1
that secure the heatsink to the system board tray.
6. Lift the heatsink from atop the processor
2
and set is on its side to keep from contaminating
the work area with thermal grease.
When reinstalling the heatsink, make sure that its bottom has been cleaned with an alcohol wipe
and fresh thermal grease has been applied to the top of the processor.
Ä
CAUTION:
Heatsink retaining screws should be tightened in diagonally opposite pairs (as in an X) to
evenly seat the heatsink on the processor. This is especially important as the pins on the socket are very
fragile and any damage to them may require replacing the system board.
