26 120mm Fans Tested and Compared

[Spanki]

No problem . On the cpu testing... that was one of the features that I really liked about your review. I'm not sure that the radiator numbers line up exactly (must be difference in the amount of impedence)...

If you look at the all-stars, adjusted db on radiator, at the 27-28db range (where the low speed fans top out), the FN121 is measuring just under 30cfm, the bottom end of the U1A is roughly the same (but a bit louder), and the YL is pushing ~4cfm more than either of those. But then when you look at the final chart (cooling processor, adjusted dba) at that same 27-28dba range, the FN121 is doing a better job on the heatsink than the YL (which was doing better on the radiator). It's only a couple degrees, but the radiator chart kinda paints a different picture, as it were .

Maybe if the heatsink test is a pain, there's some other way to do a second test on the radiator with more/less impedence?

...of course the more interesting fans (to me, at least) are the medium speed ones, which seem to perform well in either case at that dbA level (with some breathing room on either side of that speed).
