Default New PSU or modify existing?

I have a OCZ GameXtreme 600W PSU. It works just fine but is on the noisy side, the fan has a buzzing sound to it which I don't like. Also under heavier loads the fan speeds up though the air coming out the back is still cool so it appears that the fan is controlled by load and not temps.

I am considering replacing the fan with a Noctua to shut it up. Has any one done something like this with good results? I would consider a new PSU but the noise levels mentioned in reviews are too subjective. A review I read of this PSU said the fan was "extremely quiet" which I suppose it isn't bad but not what I would call extremely quiet.

My System Specs


You'll find that either the corsair 750W or the PC P&C 750W silencer are very quiet.

Your OCZ is probably running a bit hot as you're getting into the upper range of power usage with it so the fan has to ramp up to compensate.

I've replaced a fan in a power supply .. Its not hard to do but yeah no warranty after that plus it gives you the opportunity to give it a good cleaning.. If you consider a new power supply the corsair TX750 is pretty good and can be had for $125 plus taxes in canada right now and you get a irritating $10 mail in rebate.
