> 3 dayNice and quiet on old Chillblast I5 machine easy to fit into existing holes with the new screws provided. Replaced stock case cooling fan which had become very noisy .Didnt use damper mounts as accessibility issues in case but quiet even though screwed in place. PWM 4 pins just slotted into Chan 1 fan slot on motherboard. (Asus P8Z77-V) Rebooted machine and it was detected and started up. Now Running at 750 rpm on 900 rpm low noise adapter cable provided.

> 3 dayJe cherchais à remplacer les ventilateur dun boitier Gigabyte qui étaient dorigines discrets, après avoir essayé des ventilateurs qui se sont tous révélés très bruyant, je retrouve enfin un boitier silencieux avec ces deux ventilateurs Noctua;

> 3 dayWhen you need quiet and long lasting fans, Noctua is the way to go. From 40mm to 200mm I have Noctua fans in my PC, server chassis, raspberry pi, 3d printer. I am never disappointed in Noctua. Each fan comes with numerous options for mounting and wiring. I have yet to have a Noctua fan fail or vibrate over time. No goofy color lighting, no stupid halo rings. They are fans, they move air and they do it nearly silently. This fan is in the front of my case in a custom housing I made to fit inside the top 5.25 bays. This delivers some fresh air towards my DRAM and up through my top mounted radiator.

> 3 dayContains all the bits and bobs you would expect. I particularly enjoy the short 15cm cable with 30cm extension for case fans allowing me to choose which fans go to which headers on the motherboard without having.

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.
