1. A method of activating one or more fans mounted on an exercise machine, the method comprising:
determining a user-selected fan setting for a plurality of fans designed to provide moving air to a user of an exercise machine through one or more openings in the exercise machine, the opening generally positioned around or above a height of an upper torso area of a user; and
outputting a drive signal activating the fans based on the user-selected fan-setting, wherein the drive signal accounts for current tolerance levels that can be drawn through a board-mounted transformer, said tolerance levels being near or below current levels needed to jumpstart the fans, wherein direct application of current sufficient to simultaneously jumpstart said fans draws currents at a level potentially harmful to one or more components of fan controller circuitry.
