| Wire Color | Function | Standard PC Equivalent | Notes | | :--- | :--- | :--- | :--- | | | Ground (GND) | Black | Always Pin 1 (Locking tab side) | | Yellow | +12V Power | Red | Foxconn uses Yellow for power. Do not confuse with standard Yellow (Sense). | | Green | Tachometer (Sense) | Yellow | Sends RPM signal to the motherboard. | | Blue | PWM Control (Speed) | Blue | 25kHz control signal. |

Standard computer fans follow strict color codes established by the Intel PWM specification. However, OEM manufacturers like Foxconn often use proprietary wiring sequences and connector types for specific computer brands. Understanding these variations is essential to avoid destroying the fan or your motherboard. Standard PWM vs. Foxconn OEM Wiring Matrix foxconn pva092g12h wiring diagram work
Optional: The fan will run at maximum speed without the yellow or blue wires connected. Case 3: Forcing Maximum Speed (Bypassing PWM)
Before touching the wires, understand what this fan is capable of. Incorrect wiring can burn the fan or your motherboard header.
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. | Wire Color | Function | Standard PC
Because Foxconn produces these for various brands, the physical connector is often the biggest hurdle:
The PWM wire expects a 25 kHz frequency signal. By changing the duty cycle (the ratio of time the signal is "on" versus "off"), you tell the internal driver chip how long to power the coils during each cycle.
This happens if the PWM wire (Blue) is broken, disconnected, or mapped to the wrong pin. Without the PWM signal, the fan defaults to full speed for safety. | | Blue | PWM Control (Speed) | Blue | 25kHz control signal
