Noctua Introduces Third Generation S12 Series Quiet Case Fans
Noctua is one of the most recognizable names in the computer world, with products designed to keep your system cool and quiet. Today, the company is introducing the third generation of its S12 series quiet case fans: the NF-S12A. These new fans have a "further refined blade design" and Anti-Stall Knobs that work with the new Advanced Acoustic Optimization (AAO) frame. Basically, the NF-S12A improves the airflow/noise efficiency of past models by eight percent. Its Anti-Stall Knobs "reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan's stall margin." Performance is improved on both heat sinks and radiators with the Anti-Stall Knobs, so everyone can check them out regardless of air or water cooling. The new AAO frame features integrated rubber pads to reduce vibration and Noctua's proprietary Stepped Inlet Design and Inner Surface Microstructures to increase performance.
The Noctua NF-S12A fans are available today for $21.90. There are three variations available: NF-S12A FLX, NF-S12A ULN, and NF-S12A PWM. The FLX model can operate at 1200/900/700RPM thanks to the Low-Noise Adaptors, the ULN runs at 800/600RPM for anyone needing silent operation, and the PWM features the NE-FD1 IC for automatic fan control via 4-pin headers. That last one also comes with a Low-Noise Adaptor to drop the maximum RPM from 1200 to 900.
