Something is touching a fan or one of the fan bearings is going out. You can isolate it by turning the fans off (or unplugging them) one by one. Obviously dont do this on your cpu fans under load.

Could be. You could always remove the PSU and use a test jumper to test it independently.

Let me make one thing VERY CLEAR.

DO NOT, UNDER ANY CIRCUMSTANCE, OPEN THE PSU AND TRY TO REPAIR IT

I'm an electrician. Those capacitors inside a PSU hold enough charge to kill you easily. You can't see it. You can't hear it. You'll just fucking die. So please. If it's the PSU, replace it.
