Fan/heat sink assembly

Description Spare part number

Fan/heat sink assembly (includes thermal paste and thermal pads) 441143-001

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 requirements. Exhaust air is displaced through the

ventilation grill located on the left side of the computer.

Before removing the fan/heat sink assembly, follow these steps:

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.
