12. If re-using the existing heatsink, clean and regrease it.
Caution – New heatsinks have a layer of thermal grease applied at the factory.
Adding additional thermal grease can damage the system. Follow this step only if
you are re-using a previously installed heatsink.
a. Use an alcohol pad to clean all the old thermal grease from the component
surface. Also, clean the dust from the heatsink fins.
Caution – Ensure that the thermal grease in the syringe supplied with the CPU is
pliable and not stiff. If your syringe of grease has aged, the grease might be too stiff
b. Use one syringe of thermal grease (0.2 ml/0.5 g) to carefully apply grease to
the top of the CPU in three lines in the pattern shown in
FIGURE 3-21.
