NOTE:
The original pad can be reused if the original processor and heat sink are
reinstalled together. If either the processor or heat sink is replaced, use the thermal

thermal-cooling assembly and are ready to replace it.
1 Peel the backing off the thermal cooling pad and adhere the pad to the
portion of the thermal-cooling assembly that covers the processor.
2 Place the assembly on the system board.
