Building on the proven basis of the original NF-S12 impeller, the design goal for the NF-S12B was to further improve its predecessor's much acclaimed airflow/noise ratio and to increase static pressure in order to allow for a broader range of applications. These goals have been achieved by reducing the tip clearance at the leading edge and adding Bevelled Blade-Tips, a feature first introduced with the NF-B9 92mm fan.
In addition to its highly optimised impeller design, the NF-S12B features Noctua's time-tested premium quality SSO-Bearing as well as Smooth Commutation Drive 2, the latest version of Noctua's advanced drive system that ensures superb running smoothness by eliminating torque variations and switching noises.
The NF-S12B is available in two versions: Whereas the FLX (Flexibility) version provides 1200, 900 and 600 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters in order to fine-tune it for superior airflow or maximum quietness, the ULN (Ultra-Low-Noise) version with 700/500rpm speed settings is tailor made for silent enthusiasts who demand super-slow running speeds and utmost quietness of operation.

The NF-S12B FLX and NF-S12B ULN are available immediately at a suggested retail price of EUR 19.90 / USD 24.90.
