6. Disconnect the fan cable from the system board. 7. Loosen the two Phillips captive screws and the four Phillips spring-loaded captive screws (1) that secure the fan/heat sink assembly. NOTE: Due to the adhesive quality of the thermal material located between the fan/heat sink assembly and system board components, it might be necessary to move the fan/heat sink assembly from side to side to detach the assembly. 8. Remove the fan/heat sink assembly (2) by lifting straight up. For computer models with the AMD processor, thoroughly clean the thermal material from the surface of the fan/heat sink assembly (1) and (3), and the processor (2) and Northbridge chip (4) each time the fan/heat sink assembly is removed.
