Thank you guys I replaced the AC in the room and yes the room was so hot without exhaust and weather where I live is such a hot as hell.
I used to think that I need an AC to cool the miners down where I live, temps go over 40c in the summer, but I came to understand that sufficient airflow is more than enough, you could add an AC (if you don't care about the power bill) but without exhausting the hot air fast enough, you will always run into over temp issues.
