NOTE: The thermal material must be thoroughly cleaned from the surfaces of the heat sink and processor each time the heat sink is removed. Thermal paste is applied to the fan/heat sink assembly to correspond with components on the system board as follows: the processor (1), and the Northbridge chip (2).
