> 3 dayHow can anyone complain about this fan? They probably installed it incorrectly so it runs at max rpm all the time (1200 rpm). I installed using 4-pin PWM. This fan is so quiet I cant hear it when it runs between 600-1200 rpm depending on my computers load. I now hear my refrigerator or environmental noises more. Ive included a video, its quiet even with the case side panel removed. In fact I believe my power supply fan is more audible, I may have to upgrade the PSU next. I attached this fan to my case and use it as an exhaust fan. I still cant get over the build quality of this fan, its very well engineered and seems built to last.

> 3 dayi have to physically get up and look to see if this thing was actually working or not because its completely silent. it moves a significant amount of air too!

> 3 dayDopo aver preso un dissipatore Noctua con ventola comprato anche questa ventola per lestrazione dellaria dal case. devo dire che il computer è diventato completamente silenzioso

> 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 dayThe small additional cost for this high-quality fan is worth it. Its the quietest fan Ive ever experienced, and it comes with plenty of cables, and mounts quickly and easily. Even though its practically silent, it seems to move more air than its far noisier predecessor. Its not the prettiest fan on the market by any means - the brown and beige will clash with a lot of case interiors - but I plan on replacing all four of my case fans with Noctuas.

Greater than one weekNoctua 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 dayAwesome and super quite! The anti vibration mounts are kinda hard to install in my corsair air 540 case but definitely the best fans Ive !
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.
