What can one say much ?! The NT is very quiet and, with its 80+ Gold - certification about 548 watts, which is quite good!
In my case I have about 5 fan (large and small) and the NT is by far the quietest "fan", I've ever had in my PC!
Easy to recommend only good and everyone. The cable management system is also very nice! As usual, you can, you do not need cable, simply peel off and put it back in the box. All cables are black coated and definitely long enough (for Big-Tower [myself have the Aero XPredator])
