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 Channels and 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 3-pin FLX version provides 2000/1700/1350rpm speed settings via the supplied Low-Noise Adaptors so as to give full flexibility in configuring the fan for maximum cooling capacity or near-silent acoustics. 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.
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 compound
The 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 clearance
The 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 hub
The 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.
Scope of delivery
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.

I've been a long time user of Noctua case fans, but this is the first cooler I've bought from them. Recent issues with temps getting so high (playing Star citizen) that it was causing re-boots convinced me that a new cooler was in order.
Very good build quality.
Easy to install, with clear and simple instructions, all the components fit together perfectly.
Comes with a tube of Noctua thermal paste, which is good stuff and does not need to be replaced with a seperate buy (unless you are a die-hard fan of a different brand).
Even comes with spare fan clips if you want to buy a second fan in the future for a push-pull configuration.
You can adjust the fan position if needed to clear the memory modules on cramped boards ( I needed to move the fan up about 2mm to clear mine).
Not everyone is a fan of beige...pretty much the only con I can think of right now.
Can't comment to much on noise levels, as it doesn't seem to add anything over the sound of the case fans. If anything it is a little quieter than the original cooler
In short it's dropped my temps from the high 70's ( spiking into the 90's), down to no higher than low 60's under heavy load. Granted, when I removed the previous cooler (stock) there was very little thermal paste present, so this may of been an original install failure...it's the first pre-built system I've had in the last 20 years.
I am planning a new build, and if I decide not to go with water cooloing, I'm most likely to get another Noctua cooler ( 120mm probably) to keep things simple. I don't need "flash" equipment, I lean towards reliable every time.
While this is a new purchase, so I can't speak to longevity at the moment, if my case fans are any indication then it should last for a long time. I've never had a noctua fan fail on me yet, some having been moved from one build to the next for nearly 8+ years of continuous use.
Would I recommend it? Yes. If space is an issue, and you can't go larger, then this is a very effective and easy to use cooler that does exactly what you need it to do.
Who is this for? Someone building a pc who wants no weak links and the up most effectiveness or someone who's build is small on scale and need the few fans on their rig to do more work than normal.
the only problem i had was that i orderd 2 flx and recived one flx and a pwm fan good thing my mother board supports pwm
also the fan housing is slightly diffrent than b4 so it was not fun to fit the spring clips to mount it to my NHD-14 cooler
other wise performance very good
noise levels not too loud for the amount of air it pulls out of my case
