6. Place the heatsink upside-down on a flat surface to prevent the thermal grease from contaminating other components.
7. Pull the socket release lever up to the fully open, perpendicular position.
9. Lift the CPU out of the socket, leaving the release lever in the open position.
| Note - Ensure that no thermal grease that might be left from the heatsink comes into contact with the CPU socket or underside of the CPU chip. |
Follow these steps to install a CPU and heatsink if you are replacing a CPU. If you want to install a new CPU or install a second CPU into a formerly single-CPU system, see Installing a New CPU.
|
|

7. Use the entire syringe contents to apply thermal grease in a star pattern to the top of the CPU.
| Note - If you are replacing an existing heatsink with a new heatsink, you do not need to use the syringe to add additional thermal grease to the heatsink, as new heatsinks are pre-greased. |
8. Gently distribute the thermal grease and remove any excess so that only an extremely thin, uniform layer remains. If any voids or crevices appear that could lead to air pockets, reapply the grease until you achieve a thin but compact consistency.
9. Use an alcohol pad to remove all thermal grease from the bottom of the previously used heatsink.
10. Inspect the heatsink for dust and lint. Clean if necessary.
11. Carefully position the heatsink on the CPU, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease.
|
|
Caution - If the heatsink is moved too much during its installation, the layer of thermal grease may become uneven, leading to component damage. |
12. Fasten the four screws attaching the heatsink to the motherboard. Alternate between the four screws, turning each screw two turns until all are securely fastened. See FIGURE 3-38.
FIGURE 3-38 Installing the Heatsink
13. Reinstall the air duct and the system cover.
| Note - Replacement of a CPU and heatsink should only be done by trained service personnel. If you are replacing an already installed CPU, rather than adding a new one, follow the instructions in Replacing a CPU and Heatsink. |
