Because I believe that the air-flow pressure drop with 30fpi is quite a deal higher than you've calculated...have a 24fpi rad here and it does choke air-flow quite subtantially. Am achieving better air-flow/performance with weak fans on the 14fpi rad than with the 2 x 24fpi rads. Other critical dimensions are within 10% of eath other.
