The fact is, the difference in performance between a good thin and a good/average "thick" radiator is so small as to be COMPLETELY insignificant, and I really think the whole "thin rads suck, they are useless" mindset needs to become extinct. There are literally hundreds of other factors that will have a bigger impact on your cooling performance than radiator thickness, yet they are often ignored. Simply going from Push or Pull to P-P will yield much greater gains than going from a good 40mm to a good 60mm thick radiator....
Problem with that is he's going for silence.
If he really wanted a thin radiator that would excel with push/pull he could go with the GT Stealth. That son-a-***** is 28mm thick, and has 30 sodding fins per inch.
Thicker radiators excel very well with push/pull, as with a standard RPM fan (1200RPM-1500RPM) the air has pretty much reached it's heat capacity by the time it's gotten to the other side. Increasing flowrates means lower dTs.
Anywho, I agree that a good thin rad in push/pull would be better IF he was going for performance, but that's not the case here. He wants low audibility, and higher FPI rads tend to be a bit louder than their low flow optimized counter parts.
