The fans were approx $34.00 ea. (forgot to mention that sorry..
The 6 inch fans I installed in my hot air collectors were purchased at a place that sells all commercial HVAC plumbing equipment / boilers / that kind of place because the fans and fan wiring they offer can withstand higher heat temps. CFM? not positive what they are but you want to move as much air as possible when they kick in.
Another way to go with fans would be to use 12v fans powered by a battery recharged via ev solar panel. I've seen them around for sale. If you go that route you won't be using any electricity however you'd have to deal with changing out the battery now and then once it goes ca putt.
