Gaming notebook folded closed, dangerous heat / display?

I would like to run my notebook in the closed state, I'm a little worried because he play in the GTA 5 / Battlefield 1 but something gets warm (keyboard).

The question is, can it harm the display when it is closed because of the heat? (he pulls the air from left and from below and blows it out left?

The warm CPU and GPU off-air is ventilated by fan down or sideways. No heat is dissipated via the keyboard, because all notebook foil keyboards have that would not work.

So my keyboard gets a bit warm when I put my hand on it.

Mine, too, is often the case with bad notebooks. This was not the case with the IBM T61P, for example.

Asked in MediaMarkt no problem, in the worst case, asus takes over the guarantee have so four years, and they said so ne GTX 1080 can ever be warm.

He also said heat always rises up
