I've recently built this computer, using a brand new Corsair CX600 Watt PSU. After having left the computer on all night, I awoke to it making a somewhat subtle grinding type sound; not too loud at all, but when I got in my seat I could definitely feel the vibration from it at my feet.

In addition I noticed it only occurs after longer than usual uptimes. Say it's been on all day.

It is a bottom-mounted psu, not sure if that matters, but I feel like it might since I originally had it straight on my carpet until it felt like it was running a little warm. It's now on a nice piece of laminate from my old desk.

I'd rather not ship it back, as I'll be needing it for work at the moment. Any ideas?

I have the CX430 and it did the fan running at full speed thing for a while then it quieted down. I still believe that it is an initial getting fluid/grease everywhere thing. A grinding noise is just fan issues so there is no issues with using the power supply in the meantime. My CX430 quieted down after 2 weeks of the fan running at full speed randomly and the warranty is 3 years so you can send it back at any time in the future.

It could be the fan, but it could also be something on the inside of the PSU (the PSU I'm using makes a grinding noise when I put a bit of load on it, I know it's not the fan and I hate the sound of it so I ordered a new, better quality one.) You should send it in if it bothers you, or sounds suspicious. The CX series are very poorly made and are known to make a lot of different weird noises, so you aren't alone.

I personally think you should try returning it and get a better quality PSU. :)
