What is this exactly? I couldn't really pinpoint where the noise was coming from, but I'm guessing it's the power supply? It happens after the computer is on for about a minute or so and gets louder and louder.

Have a good rated PSU so I'm a little surprised. I've never heard this noise before on any computer. Ideas?

Sounds to me like it is a bad fan.

That's kind of what I was thinking. Any solutions? I think it's the PSU fan as it seems to be the general location of the problem.

Replace the broken fan.

I had a video card doing the same thing. I replaced the fan with a GIANT heatsink replacement (fanless, best thing I added to that computer)

But yours might be the PSU

Argh yeah that's what I was fearing. Any way to 'lube up' a PSU fan? Haha...

^ I supposed you could repair/replace the fan, but you may be shocked, or worse.

I doubt it would be worthwhile to take it to any repair shop.

Sounds like a CD/DVD is trying to spin up in a broken drive and slipping

If it's just the fan in the PSU, can't you swap it out with a case fan or something ? Or just screw a normal case fan sucking air out, to the back of the PSU grid

My PSU's fan is on top, and the case of the PSU seems to be welded rather than screwed in to place. Can't take it apart.
