> 24 hourGreat cooling fan, though I have yet to see just how long it actually lasts, but based on the built quality (and the six year warranty), I dont expect longevity to be an issue. The fan is quiet and stable with little vibration. It comes with two resistors that plug in-line to reduce the fan speed if needed, a long extension connector, a 4-pin Molex connector, and both screw and rubber mounts. Unfortunately, these fans are a tad expensive, making them difficult to use on a regular basis. Also, I dont care for the over-the-top packaging. How about some bulk versions and reducing the price on these?

> 24 hourSuper quiet fans. I wanted to rackmount my gaming computer but the fans that came with the case were not designed to have somebody nearby. These were the perfect upgrade. They are a little ugly so it wouldnt be so good in a rgb build but if you want performance and quiet, these are great.

> 24 hourReally moves the air and is quiet as a feather. I have bought two more for a new computer build for my wife.

> 24 hourI have used several types of Noctua fans in 3 different PCs that I have built. I have also used them as replacement fans when the original fans in several older PCs have needed to be replaced. The build quality of every Noctua fan that I have bought (approximately 12 in all) has been superb. Noctua has become my go to brand for PC fans. I have found none better!

> 24 hourI have 8 of these installed in my mid-tower computer case. I do not have any of the sound reducing adapters installed on them (they come with 2 different ones). Not sure how to describe other than super quiet.

> 24 hourDont even have to think twice about buying these. Theyre SO worth the money compared to the cheaper ones out there. With the options for choosing your own fan speed its like having three fans for the price of one and theyre simply the best thats out there if you ask me. After buying and installing one of these bad boys, I IMMEDIATELY bought two more. Do yourself a favor and just buy this fan, theres simply no need to test it out first.

> 24 hourIve always wanted to get these fans for a long time. Ive heard so many good things and they push out a lot of mass air for the amount of sound. I only wish the color was different but Im glad I dont have to see the fans in the closed case.

> 24 hourI 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.
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.
