The fan on my PSU (OCZ StealthXtream v1 600w) is always extremely loud due to being at a high speed all the time. I'm pretty sure it isn't a heat issue since it does it after being turned on after being off all night and it's pumping out pretty cool air through the back vents. It's been in two different systems and it does the same thing.
I'm thinking it's a faulty heat sensor, any ideas?
