Cooling 250HPS Help

[Az.]

well what is a 265 cfm an how do i get one ?

i didnt actually know either....but looked into it and

""CFM= Cubic feet per minute

A rating that expresses the amount of air a blower or fan can move. The volume of air (measured in cubic feet) that can pass through an opening in one minute.""

so that fan will clear 265 cubic feet of air in 1min which is alot!!!

i guess all fans will have this to a certain extent
