Abstract
A cooling fan including a fan module, a microcontroller, and a bus interface. The microcontroller is coupled to the fan module and is capable of adjusting a speed of the cooling fan based on a status of a second cooling fan and adjusting the speed of the cooling fan based on a temperature detected. The bus interface is in communication with the microcontroller, the second cooling fan, and the system to receive and output data.
