Noctua has updated its ultra silent NF-S12 lineup of fans with the new NF-S12A. This model comes 4 years after the second generation model and is finally considered to be a "worthy successor" to its NF-S12B and is 8 percent more efficient in an airflow to noise ratio.
The new fan carries a number of new features such as Noctua's renowned Anti-Stall knobs and a revised AAO (Advanced Acoustic Optimization) frame. The frame also includes integrated anti-vibration pads and stepped inlet design along with the inner surface microstructures.
There are three variants of the NF-S12A, an FLX version with 1200/900/700 speed settings, adjustable with the low noise adapters, a ULN version with an ultra low 800/600 fan speed, also switchable with the low noise adapter, and a PWM version, which also comes with a low noise adapter to reduce the maximum speed from 1200 RPM to 900 RPM in PWM mode.
All three units come with Noctua's MTBF rating of 150,000 hours and a 6 year manufacturer warranty.
The fans are already for sale at a MSRP of $21.90.
