Abstract:
A cooling fan, system and method for controlling cooling fans in a personal computer. A unique series of sensing points is placed on a rotating hub of a cooling fan in order to uniquely identify the particular type of cooling fan. A tachometer sensor mounted in the cooling fan detects the unique series of sensing points as the cooling fan rotates and generates a sequence of pulses corresponding to the detected sending points. This generated pulse signal may be transmitted by the sensor to the fan control code. The fan control code may determine a particular type of cooling fan that the cooling fan is based on the generated pulse signal. Once the fan control code determines the particular type of cooling fan that the cooling fan is, the fan control code uses particular control parameters set for that particular type of cooling fan to control the cooling fan so that it operates optimally.
