Great writeup Phil. Having owned an SP10, and dealing with the ear-piercing scream it put out, how do the fans on the SP20 compare in pitch to those fans? I don't mind something a little loud as long as it isn't that awful screeching whine. Don't suppose you could grab a quick audio clip of the fans at a few different speeds and post it could you?
They are just as loud, but personally speaking the pitch on the fans is much more tolerable than the SP10.
