It's not hot everywhere, but in places it's pretty hot
No, that's normal.
OK
so it will never burn?
I also like little that it is so hot
No. As long as there's no short circuit. And short circuit and heat due to work is different. If it gets too warm, it turns off anyway so that no parts break
Especially at night 😂 Are there better conditions at night? Everything is fine, maybe cleaning dust.
