actually...I think, just from watching the different bake-a-round threads over time. If you buy a $2-300.00 vortex for input and for output, it will cool it down. Most people cannot afford vortex, so they use a fan that blows air and cools a bit, but is not efficient enough to really cool things down.

Turtle I am not saying your tube isn't cool, matter of fact I am building one myself...then I can compare to your results. I think harddon made his own, used 2 expensive vortex fans and his box was cooled way down.
