3. Use the cleaning pad to wipe the thermal grease from the bottom of the heat
sink.
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 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.
6. Install the heat sink onto the microprocessor as described in “Replacing the
microprocessor and heat sink” on page 304.
