interesting. so in a 65mm shroud, on a 2350 4s, im getting the same rpm as the full 70mm, but at a loss of thrust im sure. im only at 750W and about 52A or so. thanks for posting those numbers! BTW, do you have the rpm numbers for the 2w 20 in the het fan? i know at some point you compared them..???
