Finally got 'er done. (It's scary how watching one youtube video gave me the confidence to punch a 6' hole through the exterior brick wall of my new house....)
530 cfm with a variable speed controller. I do need to level the fan a bit. It is slightly canted and I think that's causing some minor vibration noises. Can't wait to try this out on my first brew day in the new house, about 10 days from now!![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
