Yeah its a monster, 20" x 20" x 2.5" total size. I was thinking that a 12v kenlow car fan would fit nice, but not sure if they would run undervolted so that it just literally ticked over, maybe I could butcher a small ceiling fan as they usually spin slow and quiet. Desk fan is an idea, but they aren't all that quiet at least the ones I have aren't.
Until I move I'll shove it outside in a cool place where there is some wind so it will probably be fine with no fan. 20 foot of 1/2 tube arrives tomorrow
so I'll attempt to get it rigged up
