EK is putting out some interesting in depth analysis about RADs lately.
(I just realized the first 3 parts are 2 years old LOL)

And that's also specifically with EK fans and rads (not a far stretch for that combo, but it might be closer to even with Noctua fans for example)
Personally I just really like the comparisons (and actual data) between all the different configurations explaining how FPI, RPM and overall thickness affects efficiency. It'l be useful for *hopefully* planing my build this year
