A thermal pad 3 is installed on the heat sink and makes contact 
with the processor. Any time the heat sink is removed, inspect the 
thermal pad for damage. 
						

							Removal and Replacement Procedures
Maintenance and Service Guide5–19
Follow these steps to replace a damaged thermal pad:
a. Carefully peel the old thermal pad from the heat 
sink area.
b. Use a plastic straight edge tool (such as a credit card) to 
remove any thermal pad residue. Glue residue does not 
need to be totally removed. The glue used on the thermal 
pad has thermal conducting properties and will flow 
together with the glue from the new thermal pad.
Ä
CAUTION: Do not use any metal tools when removing thermal pad 
residue from the heat sink or processor. Failure to follow this 
caution can result in damage to these components and system 
failure.
c. Peel the backing from the new thermal pad and position it 
on the heat sink in the same location as the old pad.
