If your Foxconn PVA092G12H is not behaving as expected, use this section to diagnose the wiring.
The Foxconn PVA092G12H is a high-quality, high-power fan that frequently confuses technicians due to its non-standard color coding (Yellow as +12V instead of Sense). By following the wiring diagram above—Black to GND, Yellow to +12V, Green to Sense, Blue to PWM—you can successfully integrate this fan into almost any system.
Remember: The "work" in your keyword refers to the physical repinning and electrical verification. Do not trust the colors; always verify continuity with a multimeter. When in doubt, throw away the OEM connector and crimp on a standard 4-pin PC fan connector following the pin functions, not the colors.
Save this guide. The next time you see a Yellow wire on a Foxconn fan, you will know it means power, not pulses.

is a standard 4-pin DC brushless cooling fan (92mm x 25mm) commonly used in Dell and HP systems. It operates on 12V DC at 0.40A and features Pulse Width Modulation (PWM) for precise speed control ranging from 900 to 3600 RPM. Standard 4-Wire Pinout & Color Coding While wire colors can vary, the PVA092G12H
typically follows the industry-standard 4-pin motherboard header configuration: Pin Number Typical Color Description Pin 1 Black Ground (GND) 0V reference. Pin 2 Yellow +12V DC Constant power supply. Pin 3 Green Sense (Tach) RPM feedback signal to the motherboard. Pin 4 Blue Control (PWM) Speed control signal from the system. [SOLVED] - Notches on 4-pin fan don't match - need adapter

is a common 92mm PWM cooling fan used in many OEM systems, such as those from HP and Dell. To make it work, you need to follow its 4-wire pinout, which typically adheres to standard PC fan color coding. Foxconn PVA092G12H Pinout Diagram If your Foxconn PVA092G12H is not behaving as
The following table shows the standard wiring for this fan model: Wire Color Description 1 Black Ground (GND) 0V connection to power supply. 2 Yellow +12V Power Main power input for the fan motor. 3 Green Sense (Tach) Outputs two pulses per revolution to monitor speed. 4 Blue Control (PWM) Accepts a 25kHz signal to adjust fan speed.

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 1 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
These features are designed to attract technicians, engineers, and DIY enthusiasts looking to integrate or repair this specific cooling fan component. Tacho output for Arduino: The Green wire outputs
If the fan does not spin at all, you can test the motor windings using a multimeter.
Cause: The motherboard does not see a tachometer (RPM) signal because the Green (Sense) wire is on the wrong pin. Fix: Double-check that the Green wire is connected to Pin #3 on the motherboard. If your motherboard expects a 4-pin fan but you have a 3-pin, ensure the Green wire is aligned with the third pad from the key.
Before closing your chassis, verify the following:
The robust build of the PVA092G12H makes it excellent for DIY projects (3D printers, grow tents, audio amplifier cooling).
Direct 12V operation:
Tacho output for Arduino: The Green wire outputs two pulses per revolution. Connect it to a digital pin on an Arduino with a 10k Ohm pull-up resistor to 5V. Do not connect the Green wire directly to 12V; it outputs 12V natively. Use a voltage divider (10k and 4.7k resistors) to step down to 5V for safe reading.
