Well, I can't say for sure but it's worth a try. Is your PSU still under warranty? It's just that your PSU is connected to the mobo, so it's natural that if your fan has problems when it is directly connected to the PSU then it would also have problems when connected directly to the mobo.
Do you have a voltmeter at hand? You could try measuring the 12V rail and see if the voltage is not fluctuating. Also, you can try removing the PSU from the computer, powering it with the metal short test while the fan is directly connected to one molex connector.
And please fill up your system specs sig so that we can help you better.
