Beautifull extreme aircooled results. The SPI times are a little high, but its a matter of tweaking .

BTW, guys, you're killing the heatpipes with air temps under 5'C. And the efficiency is very bad under 18'C. Keep in mind that the fluid inside is flowing quite slow at those ambients. It's gas/liquid at the base/middle of the pipes and jelly at the top. Most important thing is to cool the lower fins/pipes.
