Removal and Replacement Procedures - Ultra-Slim Desktop (USDT) Chassis

8.17Heatsink Assembly

1.Prepare the computer for disassembly (Section 8.1).

2.Remove the computer access panel (Section 8.3).

3.Remove any MultiBay device in the drive cage (Section 8.4).

4.Remove the MultiBay riser card (Section 8.5).

5.Remove the front panel assembly (Section 8.6).

6.Disconnect the thermal sensor and heatsink fan cables 1 from the system board.

7.Unscrew the four screws that secure the heatsink to the system board 2, then lift the heatsink from the system board 3.

ÄCAUTION: Heatsink retaining screws should be removed in diagonally opposite pairs (as in an X) to even the downward forces 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.

8.Lay the heatsink on its top in a safe area to prevent the thermal grease from contaminating the work surface.
