My ps3 is placed in a well ventilated zone, i bought mgs4 with it and it comes with a disc with some previews of movies and games. I’ve noticed that the ps3 gets a little warm, is it normal? And when i take out the disc it cames out hot, is that normal too? And also, wich is better, horizontally or vertically? Thanx 2 everyone, sorry 4 my bad english.
