Removal and Replacement Procedures— Microtower (MT) Chassis
6.12 Heatsink
1. Prepare the computer for disassembly (Section 6.1, “Preparation for Disassembly”).
2. Remove the access panel (Section 6.2, “Access Panel”).
3. Lay the computer down on its side to make it easier to work on.
4. Disconnect the heatsink control cable from the system board.
5. Loosen the four captive screws that secure the heatsink to the system board.
6. Lift the heatsink from atop the processor and set it on its side to keep from contaminating the
work area with thermal grease.
When reinstalling an existing 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. New heatsinks
come from the factory with fresh thermal grease already applied.
Position the heatsink so that fan wiring is closest to the power supply. Check to ensure that the
heatsink mounting lugs do not rest on any electrical components before tightening the retaining
screws.
Ä
CAUTION: Heatsink retaining screws should be tightened in diagonally opposite pairs (as in an X) to
evenly seat the heatsink to 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.
