Hehe, my case is quite loud, I do have like 8-9 fans in my comptuer. I mainly do it to extend the life of my computer, and besides, the only time it's irirtating is when you're trying to go to sleep, else, your music or games just drown out the noise of the fans (esp when you got a nice set of Logitech Z560's next to your computer). Course, after time, the sound of your comuter gbecomes soothing and helps you go to sleep =P.
