If a PSU swap did not fix the voltage problem, and a CPU swap did not result in any change; it is likely the motherboard.

It's probably not good for the life of the CPU, possibly RAM as well. I wouldn't recommend doing it.

Does your BIOS report voltages? I'd see what that says as well. I'd also try to get a PSU/voltage tester and try and see if you can get a 12v reading off that. If everything but HWmonitor results with 12v, then HWmonitor is just bugged.

Also if your voltage was really 9v on 12v railing then the computer wouldn't even start or boot up at all!!! So your safe, believe in Aida and don't look back.

yes bios shows 12.25 so trusting hwmonitor failed me this time just have to test everything to 2 different softwares

HWmonitor isn't the most reliable. It says my Ryzen clocks at 5GHz (its not even overclocked) and that my chassis fans run at 84rpm. You're probably right to trust Aida64 and your BIOS
