is this to hot?

Nope, not at adjectives, as long as you keep it below 70C you should be good... not sure how much it is contained by F, but it's definitely more than 84.3 :)
The threshold for my GF7900 GTX is at 100 Celcius which is equivalent to 212 F.



When this point is met, the card shuts the computer



However 84.3F seem pretty damn cold. Are you sure that it is'nt celcuis ?



If so look for dust in the lover. It might be stucked
No not too hot, of course no video card surrounded by the history of time has ever operate at a temperature that low, unless you arise to have it on the best and most expensive fluid cooling system in the world, and even next it still seems for a moment low. So either you sensor is wrong, or that is to say in Celsius which way it would be getting up there, but not too hot.
