5. Lay the heatsink on its top in a safe area to prevent the thermal grease from contaminating the
work surface.
If reusing the existing heatsink go to step 1.
If using a new heatsink, go to step 3.
1. If reusing the existing heatsink, clean bottom of the heatsink and apply the thermal grease provided
in the spares kit to the top of the processor.
2. Position the heatsink atop the processor.
3. If using a new heatsink, remove the protective covering from the bottom of the heatsink and place
it in position atop the processor.
4. Secure the heatsink to the system board and system board tray with the 4 captive screws and
attach the heatsink control cable and the thermal sensor cable to the system board.
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.
