socket
The following thermal pads are approved for use:
•
Silmore GP50
•
Honeywell
•

1. Raise the heat sink and hold it in a raised posotion.
2. Remove all traces of thermal grease or pad adhesive from the heat sink using a lint-free cloth or cotton swab
and Isopropyl Alcohol, Acetone, or other approved cleaning agent.
3. Place the CPU into the socket. Take note of the Pin 1 locator in the image below.
WARNING:Take care to prevent the pins from becoming bent while replacing the CPU. If you find it difficult to
replace the CPU using this method, or lack the tools to properly insert the CPU into the socket, then
follow the instructions provided in "Replacing the CPU (Alternate Procedure)" on page 100.
4. Apply a small amount of thermal grease or the supplied thermal pad to the centre of the heat sink. There is no
need to spread grease manually, the force used during the installation of the Thermal Module is sufficient.
5. Using a flat screwdriver, turn the CPU socket latch clockwise 180° to lock the CPU in place.
