I've got a OCZ ModXStream Pro 600W PSU and the fan makes a relatively slow rattling noise. When I tilt the whole case a little the noise stops, but when I put it back on it's feet the rattle comes back. I suspect that the bearing is the culprit here but I don't know what to do about it. The psu is like 4-5 months old so I can't give it back as I could have within a two weeks of purchase, nor can I RMA it because the the retailers would just give me back the same unit telling me it's fine and everything is within specification. So do I try and disassemble it and loose the ability to rma ir when it's really broken... or what? Whan can be done to stop the rattling if I disassemble it?
