Here’s a clear, concise text covering the wiring diagram and connections for the fan. This model is a 92mm x 92mm x 25mm DC brushless fan, commonly used in server, industrial, and high-performance PC cooling applications. Foxconn PVA092G12H – Wiring & Pinout Guide The Foxconn PVA092G12H is a 12V DC cooling fan. It typically uses a 3-pin or 4-pin connector (standard 2.54mm pitch header). Below is the standard wiring based on its model number and common Foxconn fan configurations. Standard Wire Colors & Functions | Wire Color | Standard Function | Typical Pin (3-pin) | Typical Pin (4-pin) | Notes | |------------|------------------|---------------------|---------------------|-------| | Black | Ground (GND) | Pin 1 | Pin 1 | Negative/0V power | | Red | +12V Power | Pin 2 | Pin 2 | Positive power input (10.8–13.8V DC) | | Yellow | Tachometer (Sense)| Pin 3 | Pin 3 | Output – RPM signal (open collector, 2 pulses per revolution) | | Blue | PWM Control | Not present | Pin 4 | Speed control input (25kHz, 0–5V logic) | ⚠️ Note: Some Foxconn fans may substitute Blue for a different function (e.g., locked rotor alarm), but in this model, Blue = PWM if it has a 4th wire. Always verify with a multimeter if unsure. Wiring Diagram (Text Representation) 3-pin configuration (no PWM speed control):
