My parents got a huge, and I mean HUGE, tv( I think it's HD, wait, it is). Our old tv that had to be at least 10 years old now belonged to me. I, of course, hooked up my 360 to it to play Dead or Alive 4. When I was playing, the ventilation, of course was blowing, but louder than usual. I put in Oblivion, and it was the same thing. I convinced my parents to let me put my 360 outside in the living room, onto the new tv. When I played DOA4 on it, the air wasn't ventilating as loud as it was on my tv. I think the problem was that, to channel the power of the 360 and hold the power of the 360, the tv was working overtime on it. The 360 was giving off so much air because it was cramming all that power into the tv. It runs fine now(and with less loading times).
