Need assistance with CPU fan issues? Let me know what's happening.
Your PC won't start due to a CPU fan error. You fixed it by connecting the AIO 3-pin cable correctly, but the issue resurfaces after power-on. The problem persists even after removing and reinserting the cable. Have you checked the fan connections or tried a different power supply?
When using a basic cable, it’s meant to inform the motherboard about a pump issue (usually via SATA or USB power). If the header isn’t working and you see an error, try connecting one of the radiator fans to the CPU_FAN port instead, and plug the pump into an AUX or CASE port. This might fix the problem, though it could hide underlying issues with the pump or connector. The CPU often checks for CPU_FAN during startup, making it essential for the system to run properly, which explains why errors appear when it fails.
The computer starts up smoothly without any CPU fan warnings, but the pump becomes overly active. I suggested connecting it to an auxiliary or case header, but I've checked all possible ports and the AIO continues to behave erratically.
it's not only about the pace, the fans flash a red signal and the pump also reacts
Feel free to experiment with another SATA header. Some AIOs incorporate a modular connector into the pump for SATA/RGB connections, so checking for any loose parts is important. If you share the exact model of your AIO, we can offer more targeted assistance. It seems there’s likely a problem with the AIO or its wiring, which helps us focus the possible causes.
