I_b_topping I’ve had 2 fans off Amazon from cheap brands both were flat our liars. The first was a 4 inch fan was supposed to move 250 cfm. Maybe 90 cfm with no filter. The second supposed to be 400 it may have given 150 cfm. The fan you mentions is really a booster fan and I’d be shocked if it moved 200 cfm before a carbon filter. The fan shapes that spider vevor ac infinity and mars use are really the only decent designs for actually air velocity. (I do ventilation for my occupation)

I have not tested mine. But according to their site it’s 34 db for the ac with know. And 32 db for the controller ec

Check out vevor I got my 6 inch with digital controller. It’s the same as spider farmer. I got mine on a sale for like 54 vs 125 for the “grow brands. And it’s like 60 watts at full send.

Aci is a good brand. Their connectivity does kinda make then slightly better than their competitors. That being said the fans are all made the exact same way as spider farmer vevor and mars as well. If you have the whole shebang to link them together yeah ac infinity is worth 250 but if not I’d much rather spend 70 and get an identical product. Ac infinity sets themselves apart through marketing.
