If you hit it and the noise stops, it's the PSU fan.

But, as you already know, it's a super cheap PSU with a super cheap fan. Just replace it.
 
Hey there,

Yes! Be worried. And don't hit your PC to get it to stop, that's not gonna help much. Sounds like your PSU is failing.

List your full PC specs, and we can advise in an upgrade PSU. Prob advisable not to use your PC for now.
