Is there a way to monitor the temps / fan speed of the graphics card in the 2010 mac pro. I have tried out a few utilities but nothing seems to actually reflect either the temp or speed of the graphics card itself. The reason I am curious is because last night directly following one restart I had a bunch of weird visual artifacts all over the screen until i restarted again. They all went away and havent returned since on multiple restarts trying to recreate the issue, but all I could think of was possibly overheating even though i wasnt doing anything intense at the time. Any thoughts?
