Ottawa ftwHere in Ottawa (Canada) sometimes in winter its -30 celcius outside, and even my window open fully (if my room door is closed, etc), I can manage to die from heat lol. My sig system, while under stress (games, demanding applications, etc), can melt any material known to man.
It's normal, it's a computer. If it's any good, it will produce heat, haha. Thus said, if you're running a mini-laptop with a single core atom, doubt it'll warm up the whole room.
