The CM Elite doesn't have a dongle to plug in to the mobo. I doubt that the reading you're getting in Everest/AIDA is actually the PSU; more likely an inaccurate reading. What are your system specs? Have you tried removing the side panel to get a better idea of which fan is actually making the noise? Maybe try Speedfan; it will allow you to control some of your fan speeds. Increase/decrease your fan speeds to see if you can ID the culprit.
