Whenever I boot my system up it gives me an error 515 "power supply fan not detected". It also spins the power supply fan at max rpm it sounds like. I'm not aware that motherboards had power supply fan headers, I thought the power supply just took care of itself. I went to HP website and it said to just reconnect everything (didn't work).Any ideas

That "fan header" is probably just to monitor PSU fan RPM, not controlling it. You can check this looking how many wires are connected to PSU fan header.
