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.
The following table shows the standard wiring for this fan model: Wire Color Description 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.

A wiring diagram is a visual representation of the electrical connections within a device or system. It shows the relationships between components, such as wires, circuits, and connectors, and provides a clear understanding of how the device functions. In the case of a power supply unit like the Foxconn PVA092G12H, the wiring diagram is essential for understanding how the PSU connects to the motherboard, peripherals, and other components.
The PSU has the following connectors:
: The fan operates on a 12V DC supply. The Black (GND) and Yellow (+12V) wires provide constant power to the internal motor and control circuitry.
Either the Blue (PWM) wire is not connected, or the motherboard header is not set to "PWM Mode." Fix:
