To replace damaged or contaminated thermal grease on the microprocessor and
heat exchanger, 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
exchanger.
Note: Make sure that all of the thermal grease is removed.
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.

5. Use the thermal-grease syringe to place nine uniformly spaced dots of 0.02 mL
each on the top of the microprocessor.
Note: 0.01mL is one tick mark on the syringe. If the grease is properly applied,
approximately half (0.22 mL) of the grease will remain in the syringe.
6. Continue with step 12d on page 244 of the "Installing a microprocessor and
heat sink" on page 240 procedure.
