[quote name='Pck21']So I've read that setting the console horizontally, as opposed to vertically like the old 360s, allows it to cool better? Any truth to that?[/QUOTE]
Well, heat rises, so it makes sense. If vertical, all the heat rises to a small area up top. If horizontal, the heat should dissipate over a larger surface area.
Whether it's a new or old 360, the same principle applies, horizontal placement should reduce concentrated heat.
