The thermal pads and thermal paste should be thoroughly 
cleaned from the surfaces of the heat sink 1, 2, and 3 and the

is removed. Thermal pads and thermal paste should be installed 
on all surfaces before the heat sink is reinstalled. Thermal pads 
and thermal paste are included with all heat sink and system
