That sounds like a meter of space, which is a lot. But I am not sure what CFM is in relation to a ceiling fan, and how would it be measured? The fan blades churn the air, and moving air is what we want.

I think the size and shape of the room would affect the air flow as much as anything. How close are we sitting to the fan?

I go by the blade design - the closer to a wind turbine blade, the quieter it will be relative to the amount of air flow it generates.
