> 24 hourThe fan installed without any problems in my Lian Li case and has been running for months quietly and flawlessly. Id buy them again.

> 24 hourDropped my temps by 25c idle which is honestly insanity for one fan to accomplish in my opinion

> 24 hourInstalled 4 into my rig, 3 in and 1 out. Much quieter than the box fan I was using to cool my PC(lol). Came with a nice supply of Y cables, extension, etc. Would purchase again if I needed more.

> 24 hourPurchased 4 of these almost 5 years ago: still perfectly functional and super quiet as you would expect from Noctua. Upgrading my system soon and definitely transferring them into a new case.

> 24 hourOutstanding product. My new build incorporates 4 of these bad boys, as well as 2 of their 140mm big brothers and 1 92mm little fella. Ridiculous air flow, but so quiet that on my initial boot I didnt realize the system was powered up. Compare that to my last build, which while very powerful sounds like a Harrier jet taking off inside a sandstorm.. The color scheme works perfectly inside my military green Vengeance chassis. I cant recommend these fans enough.

> 24 hourReally happy with these fans. The build quality is far above what Ive seen in other brands. I particularly like the rubber mounts and additional hardware/cable options. All details covered.

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.
