My 6870 has been getting hotter for some reason. It used to only go up to 70c-75c max but now It's going as high as 80c-85c. I have great airflow In my LIAN LI Lancool PC-K58W. I got 2 140mm's exhausting on top, 1 140mm intaking In the front and a 120mm exhausting on the back. My case temps are great In my mind(never goes above 50c-55c). When I'm gaming I put the fan speed at 35% because anything higher than that the fan sounds like a jet engine.
What's causing my temps to rise? Is the heatsink In the graphics card going bad?
