Description
Processor fan
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.
