Hi everyone. Today I woke up after fixing my cpu overheating problem the the previous night. I went to plug my PSU in this morning, and when I did, the PSU fan started spinning by itself, before I had even pressed the power button. Does anyone have any idea for why this could be happening?

Does it continuously spin? The switch was probably on when you plugged it in. Power up the PC and see if it still spins. When it receives power, it starts to spin. Shut down the PC afterwards and see if the fan still keeps spinning.
