> 3 dayIve been having moments where the Cooler Master fans in my case were making some more noise than usual at times, and it concerned me that they needed replacement.Plus, those fans were a pain in the neck to have to install in the first place, having to carefully screw them in in steps to ensure the screws didnt strip while making a path for them to install into the fans plastic and into the case to hold them securely. The screw metals were cheap.

Greater than one weekI installed two 120mm fans for exhaust on the top of my new custom pc. It works well and silent compare to other fans. Great fans.

> 3 dayExcellent quality. Grandiose packaging drives up price. Nicely quiet at 1200rpm, very quiet at 900rpm and silent at 700rpm. Moves more air than my previous Lian Li 1200rpm fans. Pricey, but if you want silence, get these.

> 3 dayCase exhaust/intake fan. As quiet as they come and hooked up to a fan header. Im very happy with all my noctua gear, and from reviews, wouldnt buy anything else. Quiet results are worth the money.

> 3 dayI cant say enough great things about these Noctua fans. They are simply very high quality. They run surprisingly quiet and smooth, they are obviously designed with care and attention to detail, and the build quality is very high. I love the built-in rubber corners for reduced vibration. The package comes with multiple cable for the different speed selections. I went around my computer room and am looking at all the noisy fans I can replace with these superior Noctua fans. Fan noise is something people get used to and you dont know how noisy bad fans are until you shut the device off. Im very happy to pay the (slight) premium in price to get such high quality. I just wished everything I bought was of this caliber of craftsmanship.

> 3 dayBeen buying Noctua fans for years. As always, they are well made and quiet. A bit pricey, but worth it in my opinion.

> 3 dayNoctua 120mm 3 Speed Setting Anti-Stall Knobs Design SSO2 Bearing Case Cooling Fan NF-S12A FLX. Replaces an old Mad Dog fan that moved a lot of air but at a high noise level. Fan kit comes with noise reducing mounting options besides the usual metal screws. Comes with speed adjustment and extension cables. Made in Taiwan with a six year warranty. It is definitely quieter while still moving air well. I can run it at full speed without limiter, so cannot attest to the anti-stall design. I would purchase from this company again.
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 FLX version provides 1200/900/700rpm speed settings via the supplied Low-Noise Adaptors in order to give you full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. 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. |

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.
