1. Turn the system board upside down, with the expansion port and external monitor port toward you.
2. Disconnect the fan cable 1 from the system board.
3. Loosen the seven Phillips captive screws 2 through 8 that secure the fan/heat sink assembly to the system
board.
4. Remove the fan/heat sink assembly 9.
✎
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.
✎
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. The numbers on the drawing identify the section of the
heat sink assembly that services its correcsponding components on the system board. Thermal paste is used on
the processor's power choke and transistor 1, the processor 2, the PCH 3, the graphics processing unit (GPU)
4, and the video random access memory (VRAM) 5 and 6. Thermal pads are used on all of the corresponding
components on the fan/heat sink assembly. 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.
