is a 92mm PWM cooling fan commonly used in systems from manufacturers like Dell and HP. It uses a standard 4-wire configuration for power and speed control. Wiring Diagram & Pinout The standard wiring for this fan model follows this pinout: Wire Color Description Black Ground (GND) Negative power supply terminal 2 Yellow +12V Power Positive DC power supply 3 Green Tachometer (Sense) Sends speed signal to the motherboard 4 Blue PWM Control Receives speed control signal from the system How it Works (#0033) 4-Wire Computer Fan Tutorial
To run the fan at 100% fixed speed , you only need to connect Pin 1 (Ground) and Pin 2 (+12V). If the PWM pin (Pin 4) is left "floating" (unconnected), the internal circuitry defaults to maximum speed. foxconn pva092g12h wiring diagram work
