Features & Package

According to Noctua, here are the major features of the NF-S12B:

"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 optimised blade geometry with Bevelled 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 warranty and versatile 1200/900/600 rpm speed settings, the NF-S12B is a premium quality fan that offers full flexibility in quiet to ultra-quiet case cooling."

Highly optimised impeller with Bevelled Blade Tips
Thanks to its further refined blade geometry with extended leading edges and Bevelled Blade Tips, the NF-S12B achieves up to 10% more airflow and static pressure than its much acclaimed predecessor at the same noise level.

3 speed settings for full flexibility
Providing 1200, 900 and 600 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the FLX (Flexibility) version can be fine-tuned for superior airflow or maximum quietness.

Smooth Commutation Drive 2
The latest version of Noctua’s advanced SCD drive system ensures superb running smoothness by eliminating torque variations and switching noises.

Noctua’s time-tested SSO-Bearing technology has become synonymous with supremely quiet operation and exceptional long-term stability.

The specifications for the NF-S12B are as follows:

  • Model: Noctua NF-S12B
  • Bearing: SSO-Bearing
  • Blade Geometry: NF-S12B Blade Design with BBT (7-blade design)
  • Rotational Speed: 1200RPM, w/LNA (Low Noise Adapter): 900RPM, w/ULNA (Ultra Low Noise Adapter): 600RPM
  • Airflow: 100.6 m³/h, 75.8 m³/h, 49.2 m³/h (59.2 cfm, 44.6 cfm, 29.0 cfm)
  • Acoustical Noise: 18.1 dBA / 10.6 dBA / 6.2 dBA
  • Input Power: 1.2W
  • Voltage: 12V
  • MTBF: >150,000h
  • Warranty: 6 years

The packaging of the NF-S12B is your standard fan cardboard box in terms of size and function. The colours of the box are brown and blue with white lettering, certainly not the most complementary scheme on the colour wheel, but on the flipside it certainly creates brand recognition. You may not agree with the colour scheme, but you certainly know it’s Noctua. The rear of the box opens to reveal some illustrations and information about the fan.

There is a small, clear plastic window in the front which gives a glimpse of the fan, along with a visible brown rubber anti-vibration mount, and adequate information on the reverse is displayed to inform you of the product basics. When you open the box you will see that the fan is packed very snug in a clear plastic molded housing.

Included in the box is the fan itself, along with anti-vibration rubber mounts, 3-to-4 pin (Molex) power adapter, screws, and low noise adapters. There are two low noise adapters: Low and Ultra Low. These are essentially little resistors that reduce the voltage and corresponding rotational speed and noise. They do the same job as a fan controller, except these are fixed to a specific voltage and a fan controller is obviously variable.
