> 3 daymonté avec les éléments en silicone, mais pas facile sur une boite déja remplie. Sont controlés par la CM en pwm sans problème. Bon bundle , Noctua quoi !

Greater than one weekNoctua is absolutely the best maker of coolers and fans, bar none. This fan is no exception.

> 3 dayPurchased 2 of these as intakes for my Solo II and they move more air than I expected for how quiet they are. On normal PWM settings I can feel air exiting the case, which is impressive as I dont have an exhaust fan. Also on normal PWM settings Im unable to hear any fan noise, at most I just air the sound of air moving. These are a significant upgrade over the TrueQuiet and TrueQuiet Pro I was using. I keep my PWM settings set to quiet and they still provide adequate cooling with less of the moving air noise. With a new baby I dont game as loud as I used to so its nice to be able to quiet down my computer as well.

Empirical experience
Greater than one weekWhisper quiet. Cant tell if PC is on sometimes. Did not use low rpm adapter.Replaced 3 Antec 1600 RPM 56 CFM basic fans.

> 3 dayIve ordered three Noctua NF-S12A PWM fans from the Noctua store, and the seller is clearly Noctua and not one of the marketplace stores. The first fan is OK. But the next two fans are used. There are screw marks inside of the screw holes and the screws are outside of the sealed plastic and are scattered all over the package. I dont know how much they used the fans before sending them to me.

> 3 dayBought to replace a similarly priced fan from another well known company that was already failing. Easy to replace the faulty item, even for me, and PC is now completely inaudible when running.

> 3 dayHonestly there is no better PC case fan for reliability and noise levels. Ive had three of these as case fans for years and something similar on my CPU cooler. I bought this extra one because my case has a filter at the bottom and I thought I might as well use it.
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.
