Thats not the power supply(PSU) specs.
And that reading is not right either.What are you measuring that voltage with?
If it really was that voltage the PC wouldnt even be running.

The motherboard sensors must be faulty,cpu fan sounds slow but is probaly only running as fast as it needs to to mantain safe temps.
