Processor fan
DescriptionSpare part number
Processor fan448162-001
NOTE:To properly ventilate the computer, allow at least a 7.6-cm (3-inch) clearance on the left and
right sides and rear panel of the computer. The computer uses two electric fans for ventilation. The fans
are controlled by a temperature sensor and are 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 grills located on the computer rear panel.
Before removing the processor fan, 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.
