Description
Fan for use in models
NOTE:
To properly ventilate the computer, allow at least 7.6 cm (3.0 in) of clearance on the sides 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.
