cool thing there is not

this is my first Mac.
have decided to use the top model because of the great power and it has not enteuscht me;
But I have indeed read about the heat problem but it's too bad I did not think.
even boot right after, without open programe un d5% cpu usage it is already strong warm.
when I look at it is a youtube viedeo really loud and still hot, louder than my 7 Their age Win PC ...
mac is good, but not this
