Hello, your motherboard only has one FAN header for the case fan, with the other two dedicated to CPU and water pump. I found information suggesting you can change the BIOS pump header mode, though the instructions weren't very clear. Some users have adjusted the pump header in BIOS to control fan speeds, which could be a good approach. If this works for you, how straightforward would it be to implement? For your model, the ASUS ROG B450 Strix I Gaming is what I own. I’m also considering exploring a pump header hack, but I’ve already purchased a Y splitter as a backup plan.

they're identical, simply insert it anywhere...

This approach ensures the water pump header starts functioning immediately without any delay, addressing your concern about default operation.

Connect the component to the CPU fan connector?

No, there isn't a setting in the BIOS to modify the pump speed.

Most AIOs display the RPM directly in the header rather than adjusting the pump speed. The header isn't meant to regulate the pump's operation. Look at the header on the AIO—if it shows just two wires, it's likely for reporting purposes.

According to what I understand, the pump header runs at full speed, 100%. I’m not sure because I haven’t assembled my new PC yet. It should be installed on Wednesday.

Intended for CPU cooler application.

I won’t rely on AI tools. I’ve seen some folks using Asus FanXpert software with a pump header, but there aren’t obvious guides on how to install it. Since your setup isn’t ready yet, you might want to check the manual or forums for similar configurations.

Use a Y-splitter or a dedicated fan controller. It seems like the effort isn't worth it.
