Abstract
Systems and methods are described for reducing high tonality sounds by controlling the speed of a fan to avoid a range of fan speeds. A target speed of the fan is determined. When the target speed is in a lower portion of the range, a signal is transmitted to the fan to operate at a speed below the range. When the target speed is an upper portion of the range, a signal is transmitted to the fan to operate at a speed above the range. When the target speed transitions from the lower portion to the upper portion, or vice versa, a signal is transmitted to the fan to progressively transition between the speed below the range and the speed above the range, or vice versa. When the target speed is outside the range, a signal is transmitted to the fan to operate at the target speed.
