I was finally able to get 101.41 and nTune installed together... (though don't know why it worked this time around)... I haven't tried overclocking, but FAN control isn't quiet working. I can control the FAN on GPU1 but NOT GPU2. Even though I have the nTune setting both fans to 99/100% you can physically see that GPU2's fan did not increase in speed. Looking at the card temps in nMonitor GPU1=61, GPU2=74 so it confirms the problem...at least its 'some' progress.
