The 360 is way to loud! I'v had 3 of them and they all sounded like a jet airplane or vacume cleaner! Its not the cooling fan but the DVD drive is super fast and makes way to much noise.

Again i cannot praise my PS3 for how silent it is! If the green power light was not turned on i would never know it was on!
