> 3 dayBought two of these to replace the stock fans on a corsair h100i water cooler for an i9900k processor. Considerable decrease in noise level and the time it revs up to cool when gaming.

> 3 dayHo usato la ventola per estrarre aria calda dalle parti superiore e posteriore di un case I-Tek. Pienamente soddisfatto sia dalla qualità che dalla silenziosità (ho utilizzato anche le ventole Arctic, che costano un terzo ma il che non possono certamente essere definite silenziose), un po meno del prezzo: venti euro per una ventola sono una cifre di tutto rispetto, forsanche eccessiva. Nessuno ci obbliga a comprarle, e saremo sicuramente ripagati da una qualità costruttiva senza pari e dal relativo confort acustico. Tornando indietro posso dire che ripeterei lacquisto senza riserve, ma non attribuisco cinque stelle unicamente per una questione economica.

Greater than one weekFan was a little pricey. But after opening box and then seeing the performance, I am totally ok buying for Noctua products. The quality of they products are top notch. They are a little noisy at max speed but that is to be expected. Great fan from a great brand.

> 3 dayIch habe die Fractal Aspect Lüfter damit ausgetauscht und konnte eine deutliche Reduzierung der Lautstärke bei gleichbleibenden Luftdurchsatz und Druck erreichen. Der PC ist nun im normalen Gebrauch nicht mehr zu hören. Qualität und Leistung sind hier wirklich top. Der Preis dafür jedoch grenzwertig hoch.

> 3 dayThese fans are Great! very quiet, all mounting hardware, definitely worth the extra cost for the quality!
The NF-S12A marks the third generation of Noctua’s signature S12 series quiet case fans, which have received more than 250 awards and recommendations from the international press. Featuring a further refined blade design with Anti-Stall Knobs that works in tandem with the new AAO (Advanced Acoustic Optimisation) frame, the NF-S12A improves the airflow/noise efficiency of its renowned predecessor by up to 8%. The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1200 to 900rpm. Its superb running smoothness, SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for quiet case cooling
AAO frame
Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.

Integrated anti-vibration padsIntegrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems. |
SSO2 bearingThe NF-S12A features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. |
Inner Surface MicrostructuresWith the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency. |
Scope of delivery
|
Anti-Stall Knobs
The NF-S12A"s Anti-Stall Knobs reduce flow separation phenomena in medium to high impedance situations and thereby increase the fan"s stall margin. This means that the NF-S12A is even more versatile than its renowned predecessor and can achieve better performance on heatsinks and radiators.
