Will my PS3 break!!!?

May be...

Omg, i left my brand new, two day old ps3 on in a closed cabinet for like 15 hours!!! I didnt mean to, whats going to happen? Im not going to play it for a day or so to let it recover...

Chill, man. It happened only once, it's OK. But next time make sure that your PS3 is in horizontal position, has 10cm gap around it. When it's off - cover it with a piece of cotton cloth, vacuum vent holes from time to time.

yea if its off and unplugged nothing will happen thrust me man!!! no problem and if on there is a possibility it might over heat

It wont overheat and break, PS3 has an automatic shutdown if it gets too hot =)

be cool man!

it wont break dude, chill, it might overheat thou if it was on

it won`t break, calm down
