Another good day. All coming together now, the ducted fan enclosure needs a few little tweaks before its joined together to prevent recirculation but it looks ok to me.

Its still pretty close under there, but its got about 5-6mm off the pulley:

The logic is that a decent sized rad and 8" fan will dump heat fast, so the fan won't have to run for very long, so increasing it's service life.
Ducted fans are also more efficient, because they pull air across the entire matrix with no risk of hot spots at the corners.
Under 2.8m of hose used too, so thats less weight carried and more money available to spend on decent components.
