is this tjunction temp ? if it is then no problem , but if it's the "basic" temp , yeah maybe a little high ...
you can try to manually change the fan curve for example try to set it at 100% after 75-80° to check, but if this doesn't help maybe you have to change thermal paste
if card is too hot it can auto throttle to try to cool by autolowering it's perfs until temps are cooler
