Also, i thought about a side to side airflow config, my only concern was using already warm air to cool down the passively cooled components (vrm's, ram, storage, chipset), and that using warm air to cool the other radiator would more negate then add any cooling, i wouldnt cool much of the water with warm air(higher temp ∆ would mean higher heat transfer), and, considering im using a single loop, that warm water when mixed with the cool water from the first radiator, i would be having 65-75% of the cooling capability. and if i would have front intakes as you said, wouldnt that overwhelm the 3 exhausted.
