Note: SilverStone Suscool 121, Noiseblocker NB-Multiframe MF-12-S1, Scythe Gentle Typhoon B2AP-12 and B1AP-11, Noctua NF-S12B ULN and Scythe Kaze Maru 12L worked at their maximum rotation speed and still generated less than 33 dBA of noise. For exact noise readings, please see the corresponding charts.
The fact that the chart doesn't hit below 30db, that says something about the instrument he used. a minority of those fans do hit below that sound level.
