How hot is the slim supposed to get?

It's been a few years since i had my old elite, so i can't remember how hot that got in good room temp. But i felt my slim after playing reach for a few hours and im supprised how hot it was. Now the air flow is good above and to sides of it. But im curious if its supposed to get hot after playing. I mean i know its not gonna be ice cold lol.

My slim doesnt seem to get as hot as my older one even after a few hours of gaming

I upgraded to 250GB slim recently from an old 20GB pro and it does feel hotter.

Long as the heat is escaping through the vents then it will be ok. I would be more worried if the 360 got that hot without any vents.
