So I got the C6 fan today. Not surprising, made in Taiwan, but who cares, iPhones are made in Taiwan too...
The fan assembly doesn't match the picture that is posted on Amazon. I don't know if there was a design change on these at some point, but here is what I got:
The fan blade is 16.5" and it comes with the right connector to plug it into the C6 fan controller. There is even a little molded cradle for it. Imagine that.
Just let me know if anyone wants any other measurements.
