> 3 dayUn produit très silencieux, par rapport à mon ventilo dorigine. Tellement silencieux quune fois lordi remonté, jai fait un test sensor pour massurer que le ventilo tournait bien ! Et il tourne, mais... en silence :)

> 3 dayReplaced the factory intake fan and exhaust fan with an F12 and S12 and noticed a 18dBA difference about 3 feet from my case, which is insane (about 1/4 the perceived volume). Quiet as a whisper and really easy to install.

> 3 dayPresa per sostituire le ventole del case che a mio giudizio erano troppo rumorose, avendo letto di tutto e di più sulla silenziosità di queste noctua, son rimasto leggermente dispiaciuto, me le aspettavo un pò meglio ma a questo punto probabilmente son io ad essere troppo pretenzioso.. Ovviamente hanno il solito colore osceno della Noctua immancabile

> 3 dayNoctua is a no brainer buy. Every review holds them at the top for good reason. Their technology and support is unmatched.
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.
