I have a 7' 3" x 7' 4" x 8' room. I have a 6" extraction fan the has a CFM on 435. From What i worked out i need at least need to move 1500 cfm is this correct??
 
Yea, I think you need a little more than 435cfm for a room that size. it'll probably work though as long as it doesn't get too hot.
 
Thats just a bit bigger then my box and my 6" vortex is more then enough. I have it about half speed, but i also use 22 cool tubes
 
ive been using a 104 cfm inline for venting and a box fan and ocolating for movement in my 7x4x7 box with a 1000w

7.3 x 7.4 x 8 = 432 Cubic Feet. Your fan is able to move all the air in your room every minute. You don't need a bigger fan.
