PSU fan seems to randomly make sound like it's rubbing up against something, but the sound goes away when I put the PC tower on its side, or even if I slightly move/shake the PC tower. What could be the reasons for this? Fan bearings?
Is there anything I may have done to cause this, or is it a manufacturer defect/issue? Worth RMAing?
