Thermal grease

Use this information to determine the guidelines for using thermal grease on a
heat sink and processor.
The thermal grease must be replaced whenever the heat sink has been removed
from the top of the microprocessor and is going to be reused or when debris is
found in the grease.
To replace damaged or contaminated thermal grease on the microprocessor and
heat sink, complete the following steps:
1. Place the heat-sink assembly on a clean work surface.
2. Remove the cleaning pad from its package and unfold it completely.
3. Use the cleaning pad to wipe the thermal grease from the bottom of the heat
4. Use a clean area of the cleaning pad to wipe the thermal grease from the
