Is it just mine, or is this thing really loud and whiney/droney sounding when you boot up? And even after windows loads and it calms down, it still seems pretty loud.. I don't really remember reading anything about this thing being the loudest thing in the case, so maybe mines defective? Anyone else have have this problem?

it probably has some dust build up in the bearings. Take the fan off and blow it out with a can of compressed air.

Is the sound really different after it has been spinning a while? I've heard fans in PSUs that make all kinds of racket for a few minutes before settling down to a less raucous tone. They're on their last legs. If yours makes more than one kind of noise, I'd bet it's faulty.

Take it off of the motherboard (you might need to take the entire board out of the case to get the clips out), unscrew the fan off of the heatsink, remove the sticker off the bottom, and put a drop of oil into the bearings there. Stick some scotch tape over the bottom, replace the fan on the heatsink, and maybe put some better thermal paste on the chipset and heatsink (after cleaning the old gunk off) - it should be quieter now.

I had a noisy fan too... but i replaced it with a big heatsink w/o fan. (Zahlman heatsink)
If you have decent temperature inside you case, I recommend getting rid of the fan and use a bigger heatsink instead.

ah well turns out it wasn't the northbridge fan.. i disconnected it and it still made the sound.. which ended up being my gf4 ti4200's fan which is right next to the NB pretty much.. Hopefully blasting out the dust bunnies with some compressed air will fix that sound.. Would suck if my fan died while gaming or something and my VPU burned up. A dead fan that results in damaged components are covered on asus' warranties aren't they?
