My laptop GPU idles around 54C sitting flat on my bed with poor ventilation. Playing intense games, it usually sits on 69C (hehe) consistently. My old laptop would get around 80C and even 90C without proper ventilation.
80C is probably okayish for a laptop card, but you should try to use it in a way that keeps the bottom end ventilated.
It wouldn't help anyway because of how the fans are oriented
wtf that's horrible ventilation on a laptop.
and is that a "subwoofer"?
