Abstract
A communication method for a fan includes transmitting an initial signal with a specific duty cycle pattern to the fan; entering a communication mode after the fan receives the initial signal; reading information of the fan by a firmware of the fan; and transforming the information of the fan into a fake tachometer (TACH) signal and transmitting the fake TACH signal to a controller via a TACH signal line under the communication mode.
