TRUST ME some games out there kill the graphics chip (baking hot) so the solder melts on them, best bet is get the board reballed with LEADED solder balls and you shouldnt have any probs! other thing i would recommend is get them 3fans that you can plug on the side or something too keep it cooler
also the fact that ps3 uses a low rpm single fan means it cant get rid of the heat quick enuff, ive taken both the ps3 and 360 apart and think the ps3 is probably the worst design for cooling because iirc the fan sits under the motherboard and it collects a huge amount of dust inside the console
thats a good point. mine wasnt anywhere near as bad as some of the pictures seen on the net.. but bad none the less.
found a good fan on amazon that is rated quite highly... unfortunately it is sold out.
