What are you planning to plug this fan into?

If you have salvaged a heatsink from a Dell, HP, or Lenovo workstation, or if you are repairing a high-end server power supply, you have likely encountered the . This 92mm dual-ball bearing fan is renowned for its reliability and high static pressure. However, its proprietary connector often turns a simple replacement into a wiring puzzle. foxconn pva092g12h wiring diagram work

Pin 3 outputs a series of digital pulses as the fan spins. The internal sensor outputs two pulses per revolution. The motherboard reads the frequency of these pulses to calculate the exact Revolutions Per Minute (RPM). If this wire is disconnected, the fan will still spin, but the system will display "0 RPM" and may trigger a "Fan Failure" error during a computer's boot sequence. PWM Speed Control

If your fan has a standard square plastic connector with two guide rails, it will likely plug directly into any modern motherboard. | Wire Color | Function | Standard PC

For remote ON/OFF control, connect the remote ON/OFF pin (Pin 1) to a switch or a digital signal, and connect the GND pin (Pin 2) to the system ground.

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. | | Blue | PWM Control (Speed) | Blue | 25kHz control signal

Before touching the wires, understand what this fan is capable of. Incorrect wiring can burn the fan or your motherboard header.
