your xfx is voltage locked at 1.17 when other people are running 1.0 to 1.05 volts, so your card will always run above 80 degrees, probably 85 degrees if the case is open and you put a fan on it, otherwise maybe even over 90 degrees.

best thing to do with that card is to flash it to the gigabyte bios, keep your case open and have a fan blowing on the video card.

its one of the worst cards to mine with in my opinion but you can easily get 730 khash on it with core at 1080 and memory 1500.
