A system is provided, which manages, by a microcontroller internal to a fan installed in a server, power data associated with the fan, wherein the fan includes two pins configured to communicate signals based on an inter-integrated circuit (I2C). During operation of the fan, the microcontroller measures a first and second amount of power consumed by the fan at a first and second time. The microcontroller transmits, via the two pins, the information to a system management entity which monitors and manages the server, wherein the system management entity controls a speed of the fan in response to receiving the measured power data and based on a net power comprising a difference between a total amount of power consumed by the server and an amount of power consumed by the fan.
