The op of the CN thread advises that the suggested setup in that article isnt the best way to do it.
A fan blowing across the primary with exit holes on the opposite side cannot channel the warmer air out of the tube without it rebounding and bouncing around in the light path.
It would probably make more sense for the side mounted fan to be sucking rather than blowing.
