Best way to cool it down?

TYLER: I've got a second box that is currently unmodded so I might try to do the 80mm fan install. I bought the box cheap and was going to keep it unmodded for XBL; my mod'd box runs hot when booted with the chip disabled. Did you follow any tutorials that you might point me in the direction of?

ADAM_T: Good to hear it worked out. Still curious though; how hot was the box temps before? I don't know a lot about electronic theory, but I think its a bit ludicrous to implement a cooling fan at 20% output. It seems more often than not that the cooling efficiency is inadequate, even on unmodded boxes; I've known a handful of people who've burned out boxes under moderate gameplay conditions (and the weather's never that bad around here, California).
