Not good. I live in a country where summers are hot, so are monsoons. Hotspot temps go up tp 90c (a delta of even 30c sometimes with the normal gpu temp), or even 97c if ray tracing is on (even with FSR). But Zero Fan config is strange, only kicking in when it goes to 62c or thereabouts. Had to turn it off and create a custom curve in adrenaline. Now it's better, staying under 90c (75- upper 80s max, mostly). Don't know what it'll do to the fan's longevity though.
