Wow... So Xbox customer support is dumber than I expected.
I specifically said that my controller was squeaking...
They told me my CONSOLE was making a noise because when I loaded a disc the fan comes on and that's nothing to worry about.
I really do like the controller, though. I think it's pretty comfy and the layout is pretty good. The only things I wish I could change are the ABXY configuration (I'm still used to the Japanese/Nintendo way) and the D-pad.
