Abstract
An intelligent fan with interface compatibility is provided. The intelligent fan includes a fan body having a fan and a motor, a driving circuit, a tachometer, an output connector including a first pin, a second pin, a third pin and a fourth pin connected to a fan connector of a motherboard, and a microcontroller connected to the driving circuit and the tachometer, and connected to the motherboard via the first, second, third and fourth pins. When the intelligent fan is powered on, the microcontroller sets the third and fourth pins as input pins for receiving an output signal of the fan connector of the motherboard, and the microcontroller performs an I2C signal analysis on the output signal. When the I2C signal analysis succeeds, the intelligent fan is set in an I2C mode, and when the I2C signal analysis fails, the intelligent fan is set in a PWM mode.
