NF-S12B FLX
From our tissue paper test above, it's very obvious that the Noctua NF-S12B FLX (Shown on the left) moved much more air than the Noctua NF-S12B ULN (Shown on the right), since the NF-S12B FLX spins almost twice as fast as the ULN version by default. The FLX at full speed provided tons of airflow as well as relatively adequate static pressure to keep the inside part of the tissue floating in the air, while keeping its end off the ground, thanks to an abundance of fast moving and stable air. As always from Noctua, airflow is very consistent, and we noticed very little fluttering. [...] Whatever your justifications may be, you definitely cannot go wrong with either of the two -- they are refined, high performance, reliable, quality, and quiet case fans for the noise conscious computer enthusiast!
"What Noctua did right here, is actually quite an achievement. They took what already was one of the best case fans in the market, and made them even better! By modifying the blade tips, it improved the amount its fan's capable airflow, as well as static pressure, while dropping noise levels all at the same time." (Jonathan Kwan, APHNetworks.com)
