everytime i turn on my pc, the cpu fan suddenly speeds up(louder) and it goes way past 60dba in less than 2 seconds and it keeps going higher, so everytime i have to unplug the power supply quickly to stop it spinning, because i think it may blow up.
i have no idea what to do, please help.
the fan is a Delta Electronics DC BRUSHLESS AFC0912DE
thank you!

Have you tried plugging the fan into a different pin on the motherboard?
