ps slim question

i have a ps 3 slim, after playing for 1:30 mins. and turn it off, i touch the toprear part of ps 3 logo . it is hot.

is this normal?

andare all the slim will get hot after more than an hour playtime?

Normal, it gets hotter because the shell of the console is closer to whatever is inside... or something like that. Don't worry about it, just enjoy your PS3.

Yes after playing any system it will get hot, but what helps is buying a fan for it, it should only cost 20 bucks.
