Pin Configuration

  • 80mm Aluminium CPU Heatsink Documentation
  • Pinout Explanation
  • The 80mm Aluminium CPU Heatsink is equipped with a 3-pin connector for fan connection and a 4-pin connector for PWM fan control. Below is a detailed explanation of each pin:
  • 3-Pin Fan Connector
  • 1. VCC (Power): This pin provides power to the fan. It is connected to the positive terminal of the power supply. Typically, this pin carries a voltage of 12V.
  • 2. GND (Ground): This pin provides a ground connection for the fan. It is connected to the negative terminal of the power supply.
  • 3. SIGNAL (Fan Signal): This pin receives the fan control signal from the motherboard or fan controller. The signal is used to regulate the fan's speed.
  • 4-Pin PWM Fan Connector (optional)
  • 1. VCC (Power): This pin provides power to the fan. It is connected to the positive terminal of the power supply. Typically, this pin carries a voltage of 12V.
  • 2. GND (Ground): This pin provides a ground connection for the fan. It is connected to the negative terminal of the power supply.
  • 3. PWM (Pulse Width Modulation): This pin receives the PWM signal from the motherboard or fan controller. The PWM signal is used to regulate the fan's speed by varying the duration of the pulses.
  • 4. SENSE (Fan RPM Sense): This pin is used to sense the fan's RPM (revolutions per minute). It provides feedback to the motherboard or fan controller, allowing for precise fan speed control.
  • Connecting the Pins
  • To connect the pins correctly, follow these steps:
  • Step 1: Identify the connectors
  • Identify the 3-pin fan connector and the 4-pin PWM fan connector (if available).
  • Ensure the connectors are securely attached to the heatsink.
  • Step 2: Connect the fan
  • Connect the fan's power wires to the VCC and GND pins on the 3-pin fan connector.
  • Connect the fan's signal wire to the SIGNAL pin on the 3-pin fan connector.
  • Step 3: Connect the PWM fan (if applicable)
  • Connect the fan's power wires to the VCC and GND pins on the 4-pin PWM fan connector.
  • Connect the fan's PWM wire to the PWM pin on the 4-pin PWM fan connector.
  • Connect the fan's RPM sense wire to the SENSE pin on the 4-pin PWM fan connector.
  • Step 4: Secure the connectors
  • Secure the connectors to the motherboard or fan controller using the provided screws or clips.
  • Important Notes
  • Ensure the fan is properly seated and secured to the heatsink to prevent damage or noise.
  • Verify the fan's power consumption and voltage requirements match the power supply's output.
  • Consult the motherboard or fan controller manual for specific fan connector pinouts and connection instructions.
  • By following these steps and understanding the pinout explanation, you can successfully connect the 80mm Aluminium CPU Heatsink to your system and ensure proper fan operation and temperature control.
