The NF-A12x25 is a highly optimised next-generation 120mm fan that integrates Noctua’s latest innovations in aerodynamic engineering in order to achieve an unprecedented level of quiet cooling performance. It takes state-of-the-art technologies such as the AAO (Advanced Acoustic Optimisation) frame or Flow Acceleration Channelsand combines them with a record tight tip clearance of only 0.5mm, which is made possible by using the novel Sterrox liquid-crystal polymer (LCP) compound as well as a metal-reinforced motor hub and axis for ultimate precision. Following the approach of Noctua’s A-series, the NF-A12x25 is a true all-rounder that yields superb results in all types of usage, regardless of whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on heatsinks and watercooling radiators. The 4-pin PWM version supports fully automatic speed control via PWM fan headers and comes with a Low-Noise Adaptor to reduce the maximum speed from 2000 to 1700rpm. Topped off with exceptional running smoothness, Noctua’s reference-class SSO2 bearing and a rich bundle of accessories, the NF-A12x25 is a premium-quality product through and through. Its superior efficiency, cutting-edge construction and pioneering materials make it an elite choice for the most discerning demands.

Next-generation performance
Noctua’s 120mm fans such as the NF-F12 and NF-S12A are renowned as being among the best on the market and have received more than 400 awards and recommendations from the international press. With its further improved efficiency and novel, state-of-the-art engineering, the NF-A12x25 represents another step up in performance and manufacturing.

Sterrox liquid-crystal polymer compoundThe NF-A12x25’s impeller is made from Noctua’s novel Sterrox liquid-crystal polymer (LCP) compound that features extreme tensile strength, an exceptionally low thermal expansion coefficient and damping characteristics that are ideal for reducing resonance and vibration phenomena in advanced fan-blade designs. |
Ultra-tight tip clearanceThe NF-A12x25 has a record tight tip clearance (distance between the blade tips and the inside of the frame) of only 0.5mm. This highly ambitious design sets a new benchmark for 120mm fans and helps the NF-A12x25 to work more efficiently against back pressure, such as on heatsinks or radiators, by reducing leak flows through the gap between impeller and frame. |
Metal-reinforced motor hubThe centrepiece of the NF-A12x25’s motor hub is made entirely from steel and the axle mount is reinforced with an additional brass structure. In combination, both measures ensure ultimate precision and increased stability in the critical hub area. |

Highly optimised P/Q curve for all applications
The NF-A12x25’s sophisticated aerodynamic design allows for a pressure to airflow (P/Q) curve that is extremely strong in the critical mid-section. This means that the NF-A12x25 offers excellent performance in both static pressure demanding and airflow demanding applications.

Since I purchased this fan, Noctua has released a low-profile cooler for ITX applications.
Although on the pricey side, let me tell you that the quality is truly premium. They are heavier, solid, and pictures online do not do them justice if you must know. The colors might make you feel you are getting something retro made in the 80s, however- these are far from that acid plastic used back then. The corners are brown silicone, the fan looks like carbon fibre (I have not read the details on materials), it looks like it, and its just so solid overall. Compared to the rinky dink fans he had previously (Arctic), these are like a Rolls Royce.
The packaging is also premium. Attention to detail in all manners. They specialize in fans for a reason. You can tell, they take pride in making their products.
I understand what all the fuss is about, with thousands of 5 star ratings online.
Installation was easy, and the temperature dropped about 5 degrees. I will double check if it is not 7 degrees cooler. It is MIND BLOWING how silent they run, and how overall my entire tower is so quiet and cooler. We both come from an era in the 90s where towers were loud.
If you are a gamer, or need high-performance cooling because you are running software, I highly recommend these. Don't try to save here. Just get these fans and you will not regret it. Peace of mind is priceless and so is quality!

I liked the rubber frames that came with it...no air leaks and it all goes to the radiator.
- Very solid, well made materials.
- Best thing ever: extremely flexible and soft cables. Makes your cable management very easy and they don't feel like they would break at all because of the flexibility or softness.
- They provide all the necessary accesories and cables for whatever it is you want to do with them. You can switch them around in the future for other uses like heatsink fan, liquid cooling radiator fan or case fan. No need to waste money for specific fan type.
- I'm running all 3 of them at max RPM and they are still quiet (compared to the corsair and nzxt fans I've owned)
- Got them all 3 with the Noctua NA-FC1 fan control, all cables provided from the NA-FC1 to connect to one single motherboard case fan which is convenient.
- Performance: Excellent static pressure and airflow performance. Will not disappoint you at all
If you're using the screws, put them in first to prime the screw holes! It'll take moment for each screw, but it'll make it easier (and quicker) to put them into the case afterwards.
The extension cords made it easy to combine multiple fans onto one header. Be sure to read the labels - one wire is an extender, the other is the low noise wire. (Last one is a Y extender for multiple fans. Easy to zip tie once you're done!)
I would recommend this to a friend building a computer for the first time. It is reasonably quiet (I must assume my tower cooler is louder, but it too is pleasantly quiet even sped up) and it moves air. Noctua is a known quantity in the space and I don't feel like I am being treated like I'm mindless by the marketing.

Met de los verkrijgbare NC-FC1 toerentalregeling kun je het toerental terugregelen en hoor je echt helemaal niks meer terwijl de ventilator nog voldoende lucht verplaatst.
Niet twijfelen, dit is een top ventilator!

Vraiment, ils font toute la différence, quasi pas de bruit même en charge et refroidissement exceptionnel !
Le prix peut faire un peu élevé, mais ils vaut largement le coup !
Je recommande à 1000%!
