1. Remove the processor identification label from the old heat sink and place it on the new heatsink in the same location.Note: If you are unable to remove the label and place it on the new heat sink, or if the label isdamaged during transfer, write the processor serial number from the processor identificationlabel on the new heat sink in the same location as the label would be placed using a permanentmarker.2. Wipe off old thermal grease on the processor with an alcohol cleaning pad.3. Check whether the manufacturing date on the new heat sink exceeds two years.• If yes, wipe off the thermal grease on the new heat sink with an alcohol cleaning pad, and goto Step 2 step 2 on page 120.• If no, go to Step 3 step 3 on page 120.Step 2. Apply new thermal grease on the top of the processor with a syringe by forming four uniformlyspaced dots, while each dot consists of about 0.1 ml of thermal grease.Figure 78. Applying thermal greaseStep 3. Install the heat sink.Note: For reference, the torque required for the fasteners to fully tighten is 1.22-1.46 newton-meters (10.8-13.0 inch-pounds).120 ThinkSystem SR665 V3 User Guide
