I have been looking into various fan/rad setups and based on the input of various persons believe that (2) 120mm's w/shroud's in push/pull config would be the best setup, then someone threw a wrench in the works.
In this corner we have the wrench, a Rotron 172mm 300CFM fan (

Btw noise does matter so they would both be on a fanbus.
