I've had my XFX HD5870 card for 3 years now. Just recently it's started giving me issues with crashing. It happens across several games including Final Fantasy XIV and even simplistic Unity 3D games like Ballpoint Universe (which pushes the card at 100% even though it has really simple graphics.) The card has always run hot under load, usually hovering around 79 degrees C, but it hasn't had crashing problems at that temperature until recently. The fan doesn't start ramping up until it hits 80 degrees, usually hovering at around 25-30%. With these games, I can prevent the video card from crashing most of the time by forcing the fan speed manually up to 55-60%. This keeps the card cooler, 60 degrees or so, but this is a bit of a hackish solution and I sent it that high just because I can't be constantly adjusting it by hand while I'm playing the game. What I'd like to do is set the thresholds on the card so that it keeps the temperature below about 70 degrees, and adjusts the fan automatically to keep it there, but there doesn't seem to be any way to set temperature thresholds on the card at all. Is there any third party application I can use to set this, or some program I can run that will adjust the fan settings for me live?
