I have a question about fans and rads, is there a method for messuring the air flow that exits a rad? I am going to get a UFO case and two Thermchill 3 fan rads, I am also going to buy Delta 252 CFM fans for rad side what faces the inside of the case. The plan is to stick 6 LED fans (Low noise high CFM) on the otherside of the RAD since Delta doesn't make LED ones and the air flow exiting the rad in all likely hood will not be 252 CFM. Does anyone know what the air flow will be or know how to figure it out?

I am also thinking of putting shrouds on but do them make them with a slope on the edges?

THanks
