So I keep reading about how supposedly quiet the PS3 is, on this board and in other places. Can we define "quiet"? Cause the fans in mine come on after a few minutes and then remain on pretty much constantly. I tried with it sitting in a completely open space (enough ventilation), vertical position, blowing canned air in it...always the same. Now, mind you, it's not vaccuum cleaner loud. I've seen laptops that sounded like airplane turbines - compared to that, it's nothing. But it's there, audible, especially when watching non-action movies. Now, when people say it's quiet, do they mean the fans do not come on and make noise at all? Or do they just mean it's quiet compared to the Xbox360, which supposedly makes a whole lot of noise? What's your experience?
