Where to connect pump on motherboard?

Are you planning to build a powerful gaming rig or a high-performance computer system that requires adequate cooling? If so, you may be considering liquid cooling solutions, which can provide superior cooling efficiency compared to traditional air coolers. When using liquid cooling, one essential component to connect is the pump. But where exactly should you connect the pump on the motherboard? Let’s explore the answer to this question and address some related FAQs regarding pump connections.

Where to Connect Pump on Motherboard?

**The pump of your liquid cooling system should typically be connected to the CPU_FAN header on your motherboard.** This header provides the necessary power and control signals for the pump to operate optimally. By connecting the pump to the CPU_FAN header, you can ensure that the pump speed is automatically controlled based on the CPU temperature.

Connecting the pump to the CPU_FAN header allows the motherboard’s firmware to regulate the pump’s speed according to the CPU load. This ensures that the pump operates efficiently, at full speed when the CPU is under heavy load, and at lower speeds during idle or low-load situations.

It is worth mentioning that some modern motherboards might have specific headers dedicated to pump connections. Such headers are usually labeled as AIO_PUMP or PUMP_FAN. If your motherboard has these dedicated headers, you can connect the pump to them instead of the CPU_FAN header. These specialized headers often provide enhanced control and monitoring features.

Frequently Asked Questions (FAQs)

1. Can I connect the pump to any fan header on the motherboard?

No, it is not recommended to connect the pump to any standard fan header on the motherboard. The pump requires more power and control signals than what a regular fan header provides.

2. What happens if I connect the pump to the wrong header?

If you connect the pump to the wrong header, it might not function correctly or receive adequate power. This can lead to cooling inefficiency or even damage your pump.

3. What should I do if my motherboard doesn’t have a dedicated pump header?

If your motherboard doesn’t have a dedicated pump header, you should connect the pump to the CPU_FAN header. Alternatively, you can use a fan hub or splitter to connect the pump to a free fan header.

4. Can I control the pump speed manually?

While most pumps are designed to be controlled automatically based on CPU temperature, some motherboard manufacturers provide software or utilities that allow manual control of the pump speed.

5. Should I connect the pump to a PWM fan header?

Yes, it is recommended to connect the pump to a PWM (Pulse Width Modulation) fan header. These headers allow for precise control over the pump speed, ensuring optimal cooling performance.

6. Is it possible to damage the pump if connected incorrectly?

If you connect the pump incorrectly or provide it with inadequate power, there is a risk of damaging the pump. Follow the manufacturer’s instructions and consult your motherboard manual for proper connection guidelines.

7. Can I connect multiple pumps to the motherboard?

Some motherboards may offer multiple pump headers or support for daisy-chaining pumps. If your motherboard supports it, you can connect multiple pumps. However, make sure you consider the power requirements and consult the motherboard manual for specific instructions.

8. Do all liquid cooling systems require a pump?

Yes, all liquid cooling systems require a pump to circulate the coolant through the system. The pump ensures efficient heat transfer from the CPU or other components to the radiator.

9. Can I use a separate fan controller for the pump?

While it is technically possible to use a separate fan controller for the pump, it is generally recommended to connect the pump directly to the motherboard. This allows for more accurate control and monitoring of the pump speed.

10. Will connecting the pump to the motherboard void my warranty?

No, connecting the pump to the motherboard will not void your warranty unless you damage any components in the process. Always handle the connections with care, ensuring that all power is turned off.

11. What happens if the pump fails or stops working?

If the pump fails or stops working, there will not be enough coolant flow, leading to overheating of components. It is important to regularly monitor the pump’s performance to prevent such issues.

12. Are there any alternative methods to connect the pump?

If your pump is not compatible with connecting to the motherboard, you can use an external fan controller or a dedicated pump controller. However, these methods may provide limited control and monitoring options compared to connecting to the motherboard.


In conclusion, when building a liquid-cooled PC, it is crucial to connect the pump correctly for optimal cooling performance. **Connecting the pump to the CPU_FAN header on the motherboard or a dedicated pump header ensures efficient and automated control of the pump speed.** Always refer to the motherboard manual and follow the manufacturer’s instructions to ensure a proper and safe connection. By doing so, you can enjoy the benefits of liquid cooling while keeping your high-performance system running smoothly and efficiently.
