PWM provided by Crystalfontz 633 LCD. Stealth fan was just placed on the delta T vs PWM% line based upon its delta T.
This was just a first stab at testing and I think the heatsink mounting wasn't especially good. I had some hassles getting the unit to mount on my 8K3A the first time. It seems like I have figured it out though now. After remounting, I am looking at CPU temperatures at 50% pwm ~5C cooler than in the graph above. So take this as VERY rough data that may not be representative of final testing results.
