> 3 dayThe hype on these fans are well deserved. They push a good amount of air and are extremely quiet even going at full speed. As for the color, its a fan so I could care less. You cant beat the warranty which dwarfs other companies. I highly recommend. These will be running 24x7 so I needed something reliable and quiet.

> 3 dayMounted 2 in the ceiling of our ice castle to circulate the warm air. Wired into the 12v lights and built a frame around them to match the wood in the shack. They dont move a lot of air, but enough to keep the warm air constantly moving and not cook the people on the top bunks ar night. Wired without the speed adjusting harness. You can hear them some, but not enough to keep anyone up at night. They use almost no power and were easy to mount.

> 3 dayIve used Noctua in the past and have always appreciated just how quiet and durable these fans are. They are not the cheapest out there, but what you get makes up for it. I purchased two of them as replacement fans for noisy Dell XPS 1.02 amp case fans. Able to run off a single mobo header using an adapter Y cable (purchased separately) since they draw only 0.12 amps each, same voltage of 12V. Each fan comes with multiple, single fan, adapter cables for extending cable length and other features (low noise, low speed, etc), screws and silicon case plugs. I went from 63db at 270Hz fan warble with that old case fan to under 36db under load. Brought inside case temps down to 31C idle and 61C loaded. Worth the money and time to install.

> 3 dayIts really tough to go wrong with Noctua. They cost more up-front but its worth it since other brands will fail and need to be replaced, costing more in the long-run. I would say other brands need to be replaced sooner but Ive never had a Noctua fan quit working.

> 3 dayDid some research into all available fans for my computer. Noctua had the highest quality and longest hours usage to bearing failure among the fans I looked at. Quiet with the use of Silicone connectors, its made a world or difference as far as much lower noise. Would recommend this highlly to anyone !

> 3 dayI wish Noctua would come up with a different color option, but Im will to deal with that for the quality of this fan. Extremely quiet and moves lots of air. I replaced all of my case fans, and its now very easy to forget my computer is even on.

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. |
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.
