every xbox 360's over heat. i got the xbox 360 elite because that has less Chance to get red rings of death. but to avoid heat and ring of death follow these steps that i do and you should be safe
1. never leave console on carpet as carpet would heat it up more
2. leave the 360 upwards, as you will see holes on both sides of the console, air needs to come out both ways, if you leave it flat it will only push air out one way and not the other and would over hear by trying to go one way
3. never leave the power plug on carpet, clothes, or any paper material. what i do is leave it on a table
4. when ever you play your 360 never leave your disc inside after you finish make sure you always take the disc out before you turn it off. otherwise turning it on while the disc in it will load while starting and hear up more
follow these steps that i do and you should never get any heat or red rings of death, iv been goin on perfect with my console like this with no errors
and no it shouldent if over heart if you play for too long. im guessing that. because i play my xbox for hours and hours or all day, still ramained great over the years thanks to the steps i do as you see above
