Input signal to adjust fan speed via pulse width modulation. ⚙️ How the Wiring Works PVA092G12H
Supplies the constant DC voltage required to run the motor.
The Green wire provides real-time RPM feedback to the motherboard. foxconn pva092g12h wiring diagram work
This connects directly to the negative terminal of your 12V power supply. It provides the reference ground for the motor and electronics.

The PVA092G12H is a 12-volt, 4-wire Pulse Width Modulation (PWM) fan. Unlike older 2-wire or 3-wire fans that control speed by varying the voltage, a 4-wire fan receives a constant 12V supply and uses a dedicated signal wire to control speed dynamically. Each of the four wires serves a specific purpose: Completes the electrical circuit.
This happens if the Blue (PWM) wire is damaged, disconnected, or if the motherboard header is set to "DC Mode" instead of "PWM Mode" in the BIOS. Without the PWM signal, the fan defaults to full speed as a failsafe to prevent overheating.

Most PVA092G12H units utilize the industry-standard Intel PWM fan pinout. If the connector is removed or the wires are cut, you must identify them by color or testing.
The is a common 92mm high-performance DC fan used primarily in Dell, HP, and Lenovo desktop systems. Understanding its wiring is essential if you are repurposing the fan for a standard PC build or a DIY project, as many of these OEM fans use proprietary connector pinouts. Wiring Pinout Guide
