It's a good amp, simple and easy to set up. But the "low noise" fans are not low noise at all! If you have ever been in the back of a rack full of professional audio gear, you'll know the level of sound that this eqpt will produce from its fans; it's like a hair blow dryer on low setting. And there's nothing variable - for low noise - about the fan speed. It's full speed, high noise from the moment you turn it on.
