Again, shazza; wise beyond your years. (forgive me ahead of time, I am enjoying a few adult beverages-its the 4th)

You are correct that I have been using this block for weeks with no water, and I never hear the fan kicking on for daily computer usage which for me is gaming, and cpu folding. Not hearing the fan kick on means the smartfan never sees the CPU above 59°C.

This was the first prototype and I had a few design changes to implement, but I am runnig out of time. I am going away for some training and sending this block to vapor was a hasty decision on my part to quell the masses. I have plans for new internals already but I figure there is no where to go but up at this point.

I just can't see how 4lbs of copper with close to 50 fins could perform so poorly, when it works with air alone and no water?
