CPU Fan Error

When ever I boot my PC, it gives me a CPU fan error warning. I use an AIO pump, and it says its working fine when I open the BIOS. This started happening after I overclocked. I have a Ryzen 5 3600 overclocked to 4.7GHz on a B450 motherboard. Please help, its annoying to have to go into the BIOS every time I boot my PC. I changed nothing in the BIOS except the overclock and RAM profile.

What is the error (pic maybe?) and what do you do in bios?

Have you restored the bios to defaults at this point and have you checked cabling to be sure nothing came loose?

I wasn't getting the error before the overclock. I restored the BIOS to default and then overclocked my CPU to a stable 4.7GHz and overclocked my RAM. Then I started to get the error. Everything is plugged into the motherboard properly. I'll restart my PC to get a pic for you.

Does the error go away if you restore bios to defaults and leave it that way for testing?

4.6ghz? with what voltages? with 1.5+ voltages it is possible with under 1.45V not possible. you probably messed up the overclock

I Use my knowledge as business owner and self taught technician aswell as an AI to help people. AI might be controversial but it actually works pretty well 90% of the time.

Do you have anything plugged into the CPU fan header? Usually that's the board complaining it isn't getting a tach input from the one fan it expect to always have (depending on the board, you may be able to disable/ignore it).
