Succeeding the vastly successful NF-S12, the NF-S12B is a next generation
quiet fan featuring Noctua's advanced SCD2 technology as well as a highly
optimized blade geometry with Beveled Blade Tips that improves its award-winning
predecessor's airflow efficiency by up to 10%. Topped off with Noctua's
time-tested SSO-Bearing, 6 years manufacture warranty and super-slow 700/500 rpm
speed settings, the NF-S12B ULN is a premium quality fan for ultra-low-noise
applications where maximum quietness has top priority.

Beveled Blade Tips, the NF-S12B achieves up to 10% more airflow and static
pressure than its much acclaimed predecessor at the same noise level.
