Air Intake
HINT: The computer turns on the fan only when the computer gets hot. It may run most of the time or very seldom, depending on your use of the
computer. Because the fan spins at a high rate of speed, it may make a noise. This noise is normal and does not indicate a problem with the fan or the
computer.
