Thermal grease

The thermal grease must be replaced whenever the fan sink has been removed from the top of the
microprocessor and is going to be reused or when debris is found in the grease.
When you are installing the fan sink on the same microprocessor that is was removed from, make sure that:
• The thermal grease on the fan sink and microprocessor is not contaminated.
• Additional thermal grease is not added to the existing thermal grease on the fan sink and microprocessor.
Note:
• Read the Safety information on page "Important Safety Information" on page 1.
• Read "Handling static-sensitive devices" on page 141.
To replace damaged or contaminated thermal grease on the microprocessor and fan sink, complete the
following steps:
1. Place the fan sink 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 fan sink.
Note: Make sure that all of the thermal grease is removed.
