The GTX590 does not overstep any reasonable limits for noise, were I to guess it is likely the quietest dual GPU card ever produced. It's also quieter than several single gpu solutions.
The 6990 is either the loudest video card ever produced, or a close second behind the infamous FX5800 Ultra.
The power use and thermals of the GTX590 are acceptable to me, as are the power use and thermals on the 6990.
Water cooling is definitely not needed for a stock clocked 590.
