I built mine day one with the vertical air intake, using Sheet Magnets to control air flow....I wore those out and now use Ceramic Magnets.
I know there have been some that tried it but had less than stellar results.
I haven't had one bit of trouble controlling temps.
I think the people that do have trouble used 3/4"od pipe, which is too small a diameter to attain good control of air flow.
I went with 1" pipe, it actually measures 1.25"od, it's the inside diameter
that measures 1", whereas the 3/4" pipe has an id of 1/2".
