The pump fan header on a motherboard powers and controls the liquid cooling pump, ensuring efficient cooling and optimal system performance.
In this article, we’ll explore what a pump fan is, its role in your PC’s cooling system, and how to use it effectively.
Understanding the Pump Fan Header:
- Definition: The pump fan header on a motherboard is a dedicated connector designed to power and control the pump of a liquid cooling system. This header ensures that the pump operates at the correct speed to efficiently circulate coolant through the system, helping to manage the temperature of critical components like the CPU or GPU.
- Purpose: Unlike standard fan headers, which control airflow, the pump fan header is specifically tailored to handle the constant operation of a liquid cooling pump. It often delivers a steady power supply to ensure the pump runs continuously, preventing overheating and maintaining stable temperatures.
How the Pump Fan Header Works:
- Constant Power Supply: The pump fan header typically provides a consistent 12V power supply, ensuring the pump runs at a constant speed. This is crucial because the pump needs to circulate coolant without interruption to maintain optimal cooling performance.
- Control Options: Some motherboards allow for manual or automatic control of the pump speed through BIOS settings or software, depending on the cooling system’s requirements. This flexibility helps in fine-tuning the cooling performance to match the system’s workload.
- Compatibility: It’s essential to connect the pump of your liquid cooling system to the designated pump fan header. Using a standard fan header instead may not provide the necessary power or control, potentially leading to inadequate cooling.
The Importance of the Pump Fan Header in Liquid Cooling:
- Efficient Cooling: The pump fan header is crucial for maintaining the efficiency of a liquid cooling system. By ensuring that the pump operates continuously and at the correct speed, it prevents the coolant from stagnating, which could lead to overheating and potential damage to components.
- System Stability: Properly using the pump fan header contributes to overall system stability. If the pump were to fail or not operate at the correct speed, it could cause the system to overheat, leading to thermal throttling or even hardware failure.
- Noise Control: Some advanced motherboards and cooling systems allow you to adjust the pump speed based on temperature readings, balancing cooling efficiency with noise levels. A slower pump speed can reduce noise, while a faster speed ensures better cooling under heavy loads.
How to Set Up and Configure the Pump Fan Header:
- Connecting the Pump: When setting up your liquid cooling system, connect the pump’s power cable to the designated pump fan header on your motherboard. This header is usually labeled as “PUMP_FAN” or “AIO_PUMP” and is often found near the CPU socket.
- BIOS Settings: Access your motherboard’s BIOS to configure the pump fan settings. Depending on your motherboard, you may have options to set the pump to run at full speed or to adjust its speed based on temperature. For most systems, keeping the pump at a constant speed is recommended for optimal performance.
- Software Control: Some motherboards offer software tools that allow you to monitor and control the pump fan settings directly from your operating system. These tools can provide real-time feedback on the pump’s performance, enabling you to make adjustments as needed.

Common Issues and Troubleshooting:
- Pump Not Running: If the pump isn’t running, check that it’s correctly connected to the pump fan header. Ensure that the header is configured to deliver the necessary power in the BIOS.
- Overheating: If your system is overheating, verify that the pump is running at the correct speed. You may need to adjust the BIOS settings or check for any obstructions in the cooling loop that could be hindering the coolant flow.
- Noise Levels: If the pump is making excessive noise, consider adjusting the pump speed through BIOS or software settings. However, be cautious, as reducing the pump speed too much could impact cooling performance.
