Abstract
A method may include providing a first pulse width modulation (PWM) signal to a microcontroller unit (MCU) included at a cooling fan. The method may further include receiving information from the MCU identifying a duty cycle of a second PWM signal generated by the MCU, the duty cycle of the second PWM signal determined by the MCU based on a duty cycle of the first PWM signal and based on a tachometer signal received from a rotor included at the cooling fan. The present current consumption of the cooling fan may be determined based on the duty cycle of the second PWM signal.
