How should I play if my ps4 is overheating, should I only play 1st and what should I watch out for?

Clean the fans. Place the PS4 in a place where it can breathe easily. Generally play in the evening or in the morning and ventilate the room well. If you dare to do it: replace thermal paste.

Should I put a fan next to it

Nice idea. You are welcome to try it ^^.

This time it went out by itself

I would recommend you to replace the thermal paste or buy and install a better fan right away, but if you don't dare to do all of this, are there any such pluggable ps4 fans on the Internet just don't know what their names are
