Replacing The System Board; Removing The System Board - Lenovo ThinkServer TS200 Hardware Maintenance Manual

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 fan sink onto the microprocessor as described in "Installing the microprocessor and fan
sink" on page 193.
