I currently have a CM eXtreme Power 600 PSU, with the stock AD1212US-A71GL.
It's been very loud recently, especially since I switched out my CPU Cooler for a be Quiet Pure Rock, which is silent. I am currently planning on replacing this fan with a be Quiet Pure Wings 2. I have a friend who has worked in the electronics/technical field for 30 years and is willing to switch out the fan, since it will most likely need to be soldered. Is this a good idea?

Well, I was thinking of this as a temporary solution, as my PSU is annoyingly loud, and I will replace the PSU later when the prices come down. If I change my mind about the fan, I can use it in my case, since I only have 1.

Is the fan loud because the bearing is worn out or it's out of balance or because it's spinning too fast?

Because the fan is driven by a fan controller, if the fan controller has failed or simply tends to run the PSU's fan faster than a better quality PSU because of the PSU's low efficient or poor component layout, then it's going to drive ANY fan you put in there at a high RPM.

I'm not sure. I might just end up working the new fan to the Mobo. I'm pretty sure the PSU fan is loud always, since a quick look online and I found it's a AD1212US-A71GL. It runs at 43 decibals compared to the 19 I'm replacing it with.

Those are bullshit numbers.

43 dbA at what voltage? 19dbA at what voltage?

And if you plug the fan into the motherboard, then you're just going to kill the PSU because the fan speed will be reactive to ambient temperatures in the case and not inside the PSU.

Suck it up and buy a new PSU instead of trying to jury rig a PSU that wasn't good to begin with.

I ended up replacing it. Hopefully the be Quiet performance is enough. I took the old fan and mounted it in the front of my case, will control with SpeedFan in Windows to keep quiet.
