To replace damaged or contaminated thermal grease on the microprocessor and heat exchanger, complete
the following steps:
Step 1. Place the heat sink on a clean work surface.
Step 2. Remove the cleaning pad from its package and unfold it completely.
Step 3. Use the cleaning pad to wipe the thermal grease from the bottom of the heat sink.

Step 4. Use a clean area of the cleaning pad to wipe the thermal grease from the microprocessor; then,
dispose of the cleaning pad after all of the thermal grease is removed.
Microprocessor
0.02 mL of thermal
grease
Step 5. Use the thermal-grease syringe to place 9 uniformly spaced dots of 0.02 mL each on the top of
the microprocessor. The outermost dots must be within approximately 5 mm of the edge of the
microprocessor; this is to ensure uniform distribution of the grease.
Note: If the grease is properly applied, approximately half of the grease will remain in the syringe.
Step 6. Install the heat sink onto the microprocessor as described in “Replacing a microprocessor and
heat sink” on page 309.
