No actually you're missing my point. What I'm saying is that you can only push or pull as much air with the fan(s) as the stronger of the 2 will move. The weaker of the 2 fans with actually just disturb the air flow created by the other fan and therefore actually reduce the total flow. You're better off just running one fan. So it's like this if on one side of the radiator you have a fan that can move 500 CFM of air and on the other side you have a fan that moves 300 CFM, you're not going to be getting 800 CFM of air flow. You probably won't even get the 500 because the weaker fan can't keep up and just gets in the way.
