I am using a system with Dual Radiaon Mobile 4870's Crossfired. When Running GPU-Z I get no output of CPU temp or Fan Speed. When Running Test Gl 3.1 - Triangle of death I get a response of 3657FPS. Does this suggest that there is a problem with one of the graphics cards. This also causes my CPU thermistor to run at +/- 100*C After 15minutes of playing any game, HON, CIV5 or anything the system over-heats and crashes. I appricate any response on getting GPU Temp/Fan speed showing, or suggestions about posisible problems.
