TL;DR:
0:58 I start the demonstration of the final product in action
1:40 I go over pictures I took of the hardware that I didn't show in the videos
9:04 I start furmark to heat up the GPU's to see what the temps look like
14:14 I go over how the code in the final product looks and works

Finally, it's done!  I got the finished product mounted inside the case and it works very well.  The fans are now barely audible in my "optimal" gaming mode, and the temperatures stay reasonable even with both gpu's being flogged.  I'll later post a quick video comparing the sound between the old case fans with no controller, against the new fans with the new arduino controller in the various modes.  I just ran out of time so I'll throw it into another video.  It's probably better that way to keep this one shorter.
