Remove the fan/heat sink assembly: 1. Disconnect the fan cable 1 from the system board. 2. Loosen the four Phillips PM2.0×10.0 captive screws 2 and the two Phillips PM2.5×5.0 captive screws 3 that secure the fan/heat sink assembly to the system board. ✎ Due to the adhesive quality of the thermal material located between the fan/heat sink assembly and system board components, it may be necessary to move the fan/heat sink assembly from side to side to detach the assembly. 3. Remove the fan/heat sink assembly 4. ✎ The thermal material must be thoroughly cleaned from the surfaces of the fan/heat sink assembly and the system board each time the fan/heat sink assembly is removed: ■ Thermal paste is used on the processor 1 and the heat sink section 2 that services it. ■ Thermal pads are used on the Northbridge chip 3 and the heat sink section 4 that services it. ■ Thermal pads are used on various other system board components 5 and 7, and sections of the heat sink 6 and 8. Replacement thermal material is included with all fan/heat sink assembly, system board, and processor spare part kits. Reverse this procedure to install the fan/heat sink assembly.
