Fan/heat sink assembly
✎The fan/heat sink assembly spare kit includes replacement thermal material.
✎To properly ventilate the computer, allow at least a 7.6-cm (3-inch) clearance on the right side and rear panel of 
the computer. The computer uses an electric fan for ventilation. The fan is controlled by a temperature sensor 
and is designed to turn on automatically when high temperature conditions exist. These conditions are affected 
by high external temperatures, system power consumption, power management/battery conservation 
configurations, battery fast charging, and software requirements. Exhaust air is displaced through the ventilation 
grill located on the left side of the computer.
Before removing the heat sink, follow these steps: 
1. Shut down the computer. If you are unsure whether the computer is off or in Hibernation, turn the computer on, 
and then shut it down through the operating system. 
2. Disconnect all external devices connected to the computer. 
3. Disconnect the power from the computer by first unplugging the power cord from the AC outlet and then 
unplugging the AC adapter from the computer. 
4. Remove the battery (see “Battery” on page 4-6). 
5. Remove the following components: 
a. Hard drive (see “Hard drive” on page 4-14) 
b. Optical drive (see “Optical drive” on page 4-9)

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.
