Why does ps4 overheat after an hour?

As I said, my ps4 overheats after an hour, so tell me the message that I should turn off my ps4, as it overheats free. Even if I then touch my ps4 it is pretty hot. However, I wonder what the problem is. I mean, my ps4 has burst at least a meter on all sides for the fans. Also, it is horizontal and I even dusted my ps4 from inside and outside yesterday. Also, it is just 20 degrees warm in my room. Also comes on the sides as usual air out. Sometimes she is also very loud.

Oh and the ps4 overheats but only with very powerful games such as cod bo4 and gta5. The problem exists for 3 days.

Does anyone have any idea why the ps4 overheats and what I can do about it?

Well, I think that the thermal grease that connects the processor and the cooling system is missing. Thus, the PS is already loud from the beginning because the whole ventilation and its concept is not working properly.

I would check if the whole heat is transported away from the heat source

Mhhh, how old is the ps4? The fan control may not work properly or the thermal pad may not be the best one.
