My little brother has one, too, and I noticed that, being the little messy guy he is, he always crowds it with all his other stuff. Really, it's crammed in between lots of other things like his toys, games, socks... god knows what else. If I was that game cube I think *I* surely would overheat. So I dunno, if your newphew isn't doing anything like that and it doesn't stand close to a heater ( like my poor DSL modem hehe) I don't think it should overheat, really. Maybe it's broken, and in that case he should be getting a new one from Nintendo, right?
