As of a few days ago, my power supply as started spinning at full speed. Every 45 - 60 seconds the fan will spin at full speed for approx. 10 seconds, then slow back down to normal. It started happening one morning when I turned on my PC. Nothing in my system or its surroundings have changed. This is really confusing me. It's a relatively new PSU (6 months) so I'm not too sure what's causing it. Its an EVGA Supernova Nex 650G. Any ideas?

Probably first signs of failure, gets overly hot inside, kicking on fans trying to help itself

That's what throws me off, though. It's blowing out cold air. Is it maybe a faulty sensor? I don't really want to risk it regardless so I'm keeping an eye out for sales this weekend, but it'd still be nice to try and figure out what's up.
