Abstract
An apparatus includes a fan and a controller configured for controlling the fan to operate in a first mode limiting rotational speed of the fan within a first range of speeds between a first minimum speed and a first maximum speed. The controller is further configured to control the fan to operate in a second mode limiting rotational speed of the fan within a second range of speeds between a second minimum speed and a second maximum speed. The second range of speeds may be narrower than the first range of speeds. Related methods are also disclosed.
