For any graphics card, id say 90 Celsius(~195 Fahrenheit) is max in my opinion i would let any gpu go(When it reaches 105 celsius(221 Fahrenheit), it (should) throtles), and i prefer to keep the gpu temperature under 80 Celsius(~175 Fahrenheit), when the gpu is stressed(Gaming etc.) And for idle temperatures, something under 50 Celsius(~120 Fahrenheit), but i prefer 30 celsius(~85 fahrenheit)
There might be some grammar mistakes in the post, (because it's not my native language), and we use metric system here so the Celsius comes from that. Yay, my first post
