internal three-speed fan provides chassis cooling. An onboard temperature
sensor controls the fan speed. The fan is always on when power is applied to
the router. Under most conditions, the fan operates at the slowest speed to
conserve power and reduce fan noise. It operates at the higher speeds when
necessary under conditions of higher ambient temperature.
