1  Using a clean lint-free cloth, remove the thermal grease from the heat 
sink. 
2  Apply new thermal grease evenly to the center of the top of the new

CAUTION: Using excess thermal grease can cause grease to contact the 
processor shield, which can cause contamination of the processor socket. 
3  Place the heat sink on the processor. See Figure 3-19. 
4  Using a Phillips screwdriver, tighten the four heat-sink retention screws. 
5  Replace the system-board assembly. See "Installing a System-Board
