What's a safe temperature for a video card?

Currently my card runs at 70-80c outside of games, and 90-100c in-game. Is that even safe? 100c is like.. 215f...|||thats way over wat it should run to be stable .... i personally would like to keep them under 80 at full load .. if the card exausts into the case then get better airflow in ur case ... the case temp and the inlet air temp of the card will effect it alot ..|||100 c is too hot your gonna fry something put some fans on the card my laptop runs at 60 c while im playing games and i get worried about that ... think anything higher than 60 c and you are asking for trouble
