according to sneaky's theory, the pressure drop of a single fan, dual pass rad is equal to 1 (speaking in a matter of units)

BIGT = 1 pressure drop
BIGTXflow = 1/2 pressure drop

so youre sayin that 2 BIGTxflow's in series will have the pressure drop on one BIGT, but will have the surface area of a BIGT240. you according to your statement, 2 x BIGTxflow's will perform better, and have less pressure drop than a BIGT240
