Complete the following steps to replace damaged or contaminated thermal grease on the microprocessor and heat sink: 1. Place the heat 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 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. Microprocessor 0.01 mL of thermal grease 5. Use the thermal-grease syringe to place 16 uniformly spaced dots of 0.01 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. Install the heat sink onto the microprocessor as described in "Installing a microprocessor" on page 44. 70 IBM xSeries 365 Types 8861, 8862: Hardware Maintenance Manual and Troubleshooting Guide
