I find it interesting to that Swiftech's own radiators only are 30mm thick and they are know for high performance systems... maybe there's something to it - but only for people who REALLY NEED SILENCE.

I have then concluded that the high fin desinty, louvered fins and so on will not change now so I'm looking for a fan that can overcome the resistance and pruduce a lot of pressure at low RPM. Therefor I'm interested in the SilverStone fans in my #1 post... they have 9 blades wich should make them good to make pressure - one of them is also 32mm thick wich also helps.

I don't hope the post is to long
hmm - iiuc the 61mm thickness of the PA120.x series include the 10mm plenums on either side - so the actual core is 40mm or so...

not sure how a dtek pro-core (readily available in denmark) would compare on air-resistance...
from the swiftech "Assessment of Radiators Performance" it is 11 FPI, but is 50mm thick
