Fan/heat sink assembly
NOTE:All fan/heat sink assembly spare part kits include replacement thermal material.
DescriptionSpare part number
For use only in computer models with Intel processors: 
●Equipped with discrete graphics subsystem memory and 8.1 processors450933-001
●Equipped with discrete graphics subsystem memory and 7.9 processors434986-001
●Equipped with UMA graphics subsystem memory446521-001
For use only in computer models with AMD processors: 
●Equipped with discrete graphics subsystem memory449960-001
●Equipped with UMA graphics subsystem memory 451860-001
NOTE:When replacing the fan/heat sink assembly, be sure that the power button board is removed
from the defective fan/heat sink assembly and installed on the replacement fan/heat sink assembly.
See 
Power button board on page 64 for power button board removal information.
NOTE: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 applications.
Exhaust air is displaced through the ventilation grill located on the left side of the computer.

Component replacement procedures 87 
						

							4.Remove the fan/heat sink assembly (4).
NOTE:Due to the adhesive quality of the thermal paste and thermal pads 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.
NOTE:The thermal material must be thoroughly cleaned from the surfaces of the fan/heat sink
assembly (1) and (2), the processor (3), and the system board component (4) each time the fan/heat
sink assembly is removed. Thermal material must be installed on all surfaces before the fan/heat sink
assembly is reinstalled. Thermal material is included with all fan/heat sink assembly, system board, and
processor spare part kits.
