> 3 dayThis is a great fan. It comes with a Y-cable (splitter), extension cable, and a low-noise adapter cable which presumably lowers the voltage so the fans spin somewhat slower than they otherwise would. Great quality. I cant hear four of these fans from 6 feet away unless I tell the motherboard to spin them at full speed. Then it shows 1400 RPMs., otherwise with PWM they usually spin at 500-700 RPMs. Note: the Y-cable is missing one of the pins on the lead to one of the fans. This is intentional so that the motherboard gets spinning feedback from only one fan; otherwise the information would be incorrect.

> 3 dayNoctua e basta, si riesce solo a sentire laria sulle mani, il rumore è talmente fastidioso (scherzo!) che non so se è in funzione oppure no.

> 3 dayEigentlich wollte ich meinen Sharkoon-Gehäuselüfter durch einen leiseren ersetzen. Daher bestellte ich den hier. Die Verarbeitungsqualität des Lüfters ist super, wie auch vom reichlichen Zubehör. Auch die Montage klappte einfach. Aber als ich dann meine Maschine einschaltete, war ich etwas enttäuscht: leiser als der bereits im Gehäuse verbaute 120er-Lüfter von Sharkoon ist er auch nicht. Von daher seine 20 EUR meiner Meinung nach nicht wert.

> 3 dayTengo puestos 4 en la caja y me mantienen la temperatura del pc a 35 grados en plena ola de calor funcionando a 800-900 rpm y sin oírse nada. Se recomiendan solos. Poco más que añadir.

Greater than one weekI had heard good things about these fans, so ha to try it out. My PC is in a enclosure in my desk and so needs to push air out the rear port. This thing does that extremely well, and with absolutely no sound. My only complaint is the rubber vibration free mounts need to be pulled and i couldnt reach the interior ones, so had to use the screws. Even with them, no vibration noise at all. Would easily buy again, and recommend to all my friends building PCs.
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.
