Change Sun is a market follower; not innovator. Their 4 blade 70mm and 5 blade fans look to be inspired by Schuebeler. IMHO, they are close, but not as efficient as other fans of the same size.
Their 10 blade 70mm fan looks has the same blade shape as this new 90mm and 120mm. Aerodynamics are aerodynamics, so things will look similar. The real question is where the inspiration came from.
If nothing else, they're going in the direction of multi-blade, lower rpm "quieter" fans.
As having tested the 70mm 10 blader, and compared it to other tested set-ups, I can tell you, you can't just use the same motor you have and expect good efficiency. The same may be true of these new fans.
