Use this procedure to install a CPU. A CPU replacement kit contains a CPU, an alcohol wipe, and a syringe of thermal compound. When you replace a CPU, the heatsink is reusable. Do not discard the heatsink.
Before You Begin
The underside of the heatsink contacts the top of the CPU.
One corner of the CPU is marked with a triangle, and one corner of the CPU socket is also marked with a triangle. These two triangles are the key and must align. When these are aligned, other keying notches and trims line up as well.
When properly installed, the CPU fits snugly within the socket.
Caution - Possible component damage. The pins in the CPU socket can be easily damaged if touched or if the CPU is installed incorrectly. Do not drop the CPU onto the socket. The CPU sits atop the socket and does not require insertion. Do not press down on the CPU. |
To ensure an even application of compound apply the contents in the shape of an asterisk.
Caution - Possible thermal-related component damage. To ensure the proper transfer of heat away from the surface of the CPU, apply the entire contents of the syringe. |
Caution - System thermal failure or component damage. Once the bottom of the heatsink contacts the top of the CPU, do not move the heatsink. Excessive heatsink movement can cause the thermal compound to smear and become uneven. This can result in voids in the compound that can negatively impact the transfer of heat away from the CPU. |
Turn each screw one-half a turn at a time.
