Many Thanks for the answer, Stefan.
For the Orochi Cu, sure it would be overkill, but considering the proto you show for the Computex with 250 mm or 330 mm fan, I think a Full Copper version of the Orochi is pretty calm
I remember there was others great protos, like the hybrid heatlane / heatpipe, or the Ninja watercooled. The big Ninja with 10 heatpipes is another great looking product, like the old fanless watercooling kit.
