I'm sorry to say that the BIX isn't really the right radiator for semi-silent operation (a bit too much resistance for low noise fans that don't generate much pressure - particularly if they're under-volted or PWMed to lower speeds).
You might want to read The Top SPCR Quiet 120mm Axial Fans Compared + 120mmAC Fans and you might also want to read this thread - mostly just Cathar's comments about radiators in air-series (and a thicker rad can be thought of as thinner ones in air-series).
Although some folks (like BillA and Ph) say that push-pull is a waste of time, I've found that fan stacking can improve efficiency-for-noise (best luck with fans stacked on the pull side with a spacer between them rather than push/pull with fans on either side of the core). This may or may not apply to your situation, depending on how low-noise you're looking to be.
