After an intensive development period, Aerocool Advanced Technologies was able to create an impressive case fan that combines the sturdiness and advantages of plastic with the flexibility and vibration absorption of rubber!
...
All nine fan-blades are constructed of dual-layer material, providing good airflow while not compromising low-noise operation! Rubber based rear side of the blades is utilizing a "Fish-Eye" surface to minimize air-turbulence. Dead Silence fan's frame design is optimized by implementing four noise absorption chambers and anti-vibration rubber layer on each corner, preventing vibrations to be transferred to the chassis or CPU cooler!
...
Both 140 and 120 mm Dead Silence case fans are equipped with a high-quality Fluid Dynamic Bearing (FDB), which stands out with a long life span of 100.000 hours (MTBF), higher precision rotation and an anti-shock function. Smallest model measures 120 x 120 x 25 mm and spins with 1.200 RPM at 12 Volts, while moving 54,8 CMF (92,9 m3/h) of air at merely audible 15,8 dBA. And it gets even better, when used with the supplied 7 Volts adapter, thanks to which fan speed is reduced to moderate 800 RPM - creating constant airflow of 36,7 CFM (62,2 m3/h) at extremely silent 12,1 dBA.

The slightly bigger 140 mm model spins with 1.000 RPM (64,8 CFM / 109,8 m3/h) at only 14,2 dBA. Operating the fan at 7 Volts drops the fan speed to 700 RPM and noise level to inaudible 10,8 dBA. Thanks to the very low 3 Volts spin-up voltage, users can adjust the noise-level and fan speed according to their preference by using the fans in combination with a fan controller.

Seems like Deja vu, they announced it in end of November or early December but I guess they launched it today

It's likely marketing gimmicks but we'll see once reviews roll in, 55-64CFM at 1000-1200RPM with 14dB-15dB is highly unlikely , in the real world. It depends a lot on how you're measuring though.
