Hi,
Just curious and need advise from "sifu" here,
For a living room, which fan (3 or 4 or 5 blades) should give a better cooling and silent?
And for bedroom, which fan (3 or 4 or 5 blades), also give a better cooling and silent?

If I am not mistaken, I understood that 4 or 5 blade will give a better cooling in a small area (not sure whether my understanding is correct?)
