ABSTRACT:
An information handling system including a system fan control for maintaining operating temperatures of electronics within the information handling system is disclosed. The information handling system can include a power trace provided in association with a power circuit that can power electronics within the information handling system. The power trace can include a reduced trace width region that may be operable to provide a temperature differential in response to a current change within the reduced trace width region. A thermistor may be provided in close proximity to the reduced trace width region and can be operable to detect the temperature differential provided in response to the current change. The thermistor may provide an input to a fan controller that may be operable to alter a fan speed to maintain an operating temperature of the electronics that may be coupled to the power trace.
