  • VCC (Red wire): 12V power supply from the motherboard or fan controller.
  • GND (Black wire): Ground connection from the motherboard or fan controller.
  • PWM (Yellow/Blue wire): Pulse Width Modulation signal from the motherboard or fan controller to control fan speed.
  • Connect the VCC and GND pins to the corresponding power supply and ground connections on the motherboard or fan controller. Connect the PWM pin to the PWM signal output on the motherboard or fan controller.
  • 2. Thermal Sensor (TMP) Pins
  • TMP (White wire): Thermal sensor output signal from the heatsink to the motherboard or fan controller.
  • Connect the TMP pin to the thermal sensor input on the motherboard or fan controller. This allows the system to monitor the CPU temperature and adjust the fan speed accordingly.
  • 3. LED Indicator (LED+) and (LED-) Pins
  • LED+ (Red wire): Positive voltage connection for the LED indicator.
  • LED- (Black wire): Negative voltage connection for the LED indicator.
  • Connect the LED+ pin to the positive voltage output on the motherboard or fan controller, and the LED- pin to the negative voltage output. This enables the LED indicator to function, providing a visual representation of the fan's operational status.
  • Connection Structure:
  • To connect the pins, follow this structure:
