Venturi effect and vortex generating design
Even very quiet weak wind may reach to the other end of your room.
this is not for intake side, but outlet side only.
Please see my other things for Venturi effect intake side for 8cm fan
(this intake version is rather extreme in size,with weird looking looks like an 16cm/6inch speaker)
Efficiency is not tested yet (about 180% to 210% than nothing at 10cm distance, I guess from other similar designs)
anycubic mega i3 with very rough setting for speed, no problem for strength,
