Over the past week or so, my 650D case has been making more noise then usual. Thing is, I don't know whats making it. I've put my finger in the middle of each fan to stop it spinning, but the noise carries on. Then when I turn the fan control to max, the humming (or what sounds like small tapping) stops! But the noise is replaced by fans spinning at high speeds. Any idea whats the issue...
 
Must be another moving part then. Check Hard drives for vibration and noise transfer to to your case by removing them from the case and resting then on something cushioned.

Other noise makers could be PSU or graphics card. You can stop PSU fan with a cable tie or something.
 
I bought one of the early models of the 650D with the excessively noisy fans. (Even at the lowest speed setting).
Corsair sent me a replacement linear fan controller which I installed at the weekend and it is a massive improvement.

I agree with Tealc. Check your other fans and hard drives.
