I ran the L1A's at 9v, which near as I can extrapolate would pretty closely approximate the Papst 4412FGL's ar 12v, and got a radiator C/W of around 0.022-0.024. Performance is clearly dropping away pretty rapidly when using fannage much weaker than that - but this would be expected as 12cm fans don't usually come much weaker than the FGL's anyway.

So yeah - definitely possible to build a radiator that should achieve very good cooling performance in a quiet and compact form factor so long as the radiator is designed to match the fan, and not the other way around which is what we have today where most of us have to get the right fan to match the radiator, and most usually, even when using the dual fan sized radiators they still require somewhat noisy fans to get to what could be considered a highish-end level of cooling.
