Product Description
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 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.

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.

They were all right, this is top of the line for sure!
I ordered 8 fans for my PC to switch out my old fans in my 2019 self-built, budget PC. All fans were replaced. The exhaust and intake, and for my new CPU air cooler (not noctua), the stock fans were replaced with these. After much research, the NF-F12 (pressure oriented) and NF-S12A (heavily airflow oriented/very low pressure), looked to be quite a sacrifice in performance over minimal price difference. AKA, the price:performance ratio wasn’t worth it for me when it wasn’t far from an A12x25 PWM.Spending $260 for some fans was painful, I’ll admit. But when the mean time to failure rate for these fans is 150,000 hours or 17.1232877 *YEARS*, and their warranty is 6 years, my investment was made (felt) easier!First off: NoiseRight before these fans, I had the redux fans installed (NF-P12 redux-1700 PWM) as my 3 – 120mm intake ones for about 2 weeks, before returning them for these A12x25 fans. And man, they were LOUD. Most of the games I play really heat up my PC (Flight sim, Star Citizen, Apex Legends), therefore my fans are often spinning on the upper side of their RPM range.These A12x25 fans at high speeds can be loud, but they have a nice white noise with acoustics that sound like they were thoughtfully engineered. Honestly, anything above 1500 RPM is noticeable. Going into this brand of fans, I had expectations wayyy too high and expected them to never make a single sound. This is definitely achievable with limiting their speeds or getting fans with ultra low noise, but that starts to cost your cooling performance.Good news though! When my PC is idling, I actually have the opposite problem where the fans are so quiet that my refrigerator hum is no longer opposed and is singlehandedly driving me crazy with its “weeerrrrrrrrrrrrrrrr”.Performance:Genuinely noticeable. Both with temp sensor reading and especially holding my hand over the exhaust fans. Again, in my previous set up had budget Arctic fans and had an AIO cooler. Now, I have all A12x25 fans and a Thermalright Phantom Spirit 120SE heatsink. My temperatures on my CPU as well as my overall GPU temps have gone down a lot. Like by 10C or more. Even on my CPU when I used the stock cooler fans on the Thermalright vs noctua fans, noticeable difference in temperature and noise there. The performance to noise ratio is phenomenal, with some games like Minecraft, GTA V, and a couple other low power games, performing well without any fan noise!Price:You get what you pay for in life. And with this fan, you DEFINITELY get what you paid for. That price is an excellent representation of its worth. I just hate myself that I justified a $33 price point per fan, but I am so happy.Quality:Fans are heavy and feel like they were built carefully and beautifully. They come with a LARGE selection of addons included in the packaging like rubber “Screws”, metal screws, pre-installed anti vibration pads around each corner, even an extra anti vibration sleeve to even further decrease vibration, a y-cable, extension cable, and low noise adapter supplies. All this included in a fancy package, with more packaging information then you could ever want to learn about with the fans.I don’t know how I feel about having so many attachments, as I only used 2 y-cable and 2 extension cords. Which leaves me with about 36 unused accessories total. Which I will obviously not throw away, but doubt I will use any more for many many years to come. So I am torn on that large surplus of accessories but at least you get more than you need, rather than needing more than you have. Having 8 fan packages open on your floor will definitely require some space, so be tidy when you open them to prevent having a large organizational mess.Overall:This fan came out on May 2, 2018, and has yet to be superseded by a better Noctua fan nor any other brand. I sincerely doubt that an upgraded version will be substantially better in the near future. Just like with video game graphics, they are already fantastic and it takes a lot to improve it just a little. I feel like it may be the same with aerodynamics and fans. In the end, this investment is worthwhile and will last you for possibly decades with a performance that will be unlikely exponentially bested in the fan’s lifetime. Do yourself a favor and start upgrading your PC fans. Start with intake first, then exhaust. Then consider your cooling systems too, but as they have the least amount of fans that make noise, I suggest starting with your case fans first in my personal opinion.The only regret you’ll have is that you didn’t buy these fans first.

Prepare to be impressed
I bought these with the sole intention to see what all the noctua hype was about and did not plan to keep them since i wasn’t a huge fan of the color scheme. Once i tried them out, there was no way i was returning them. Everything about these fans is of the upmost quality. It starts with the packaging; you’re greeted with a premium box that shows all the spec and details about the fan and how its intended to be used. Once you take the fan out of the box, you’ll notice that Noctua goes above and beyond with providing everything one would need with the fan. They include a y-splitter cable, low noise adapter and PWM extension cables in addition to the rubber quick connect pins and noise reducing gasket. Then, when you look closer at the actual fan, you see what has to be one of the best built fans ever made. There is an incredibly tight clearance between the blades and the frame – tighter than i thought was possible since the blades typically expand at full speed. There is also a smoothness that is hard to put into words when i gave it the first flick to see how they spin. Its really difficult to explain the quality any further since it is, at least in my experience, truly the best case fan ive ever seen or used. I am now looking for a new case for my pc where these will look good in since i do not like the aesthetic of these brown fans in my white build.

Installed them on a radiator they keep the CPU much cooler, AND theyâre much quieter than the ones originally came with it! No humming or loud noise even when theyâre at high speeds, and at normal CPU usage you can barely hear them. These fans lowered my CPUs temps by around 10-15c, I didnât expect them to be that much better from the previous ones.

Starka fläktar passar perfekt till radiatorer samt dom är tysta och har bra flöde. Kanon och få med en tätnings list för radiator montage

Fan is well built.The box contains lots of things, adapters, screws, rubber gasket, silicone plugs to attach the fan without screws.Operates silently but still moves a lot of air.

Recensione SpedizioneI tempi di consegna sono rispettati e precisi. Prodotto arrivato intatto.Lâarticolo corrisponde alla descrizione del venditore.La scatola è ben curata con illustrazioni ma non in lingua Italiano vedi foto, anche se per me lâestetica della scatola non ha nessuna importanza, sono interessato più alla qualità del prodotto. Allâinterno troviamo tutti gli accessori necessari per il montaggio vedi foto.Caratteristiche della ventolaNon voglio soffermarmi sulla descrizione della ventola, perché corrispondono a quelle descritte dal venditore.Recensione del prodottoCercavo una ventola di qualità e funzionale senza luci colorate o altro. Dopo un mese di ricerche e confronti con altre ventole, ho scelto la Noctua NF-A12X25 PWM.Presa per sostituire la ventola posteriore del mio case per migliorare il flusso dâaria in uscita e per diminuire il fastidioso ronzio della ventola (visto che il mio case ha solo una ventola posteriore, la ventola sostituita è stata montata nella parte superiore per migliorare il flusso dâaria in uscita).- è un prodotto di fascia alta;- semplice da montare.- qualità – prezzo: ottima la qualità il prezzo un pò alto, anche se la qualità si paga (unico modo per risparmiare è ritirala da Amazon);- unici difetti che si possono trovare a questa ventola sono: il colore (se fosse stata nera era meglio perché va bene su tutto) (anche se a me non dispiace) e la lingua (non câè in Italiano).- è funzionale garantisce un buon flusso dâaria per tenere sotto controllo il livello termico dei componenti del PC (nel mio caso da differenza tra prima e dopo è stata di un calo di 10° dai 45° sono passato a 35°).-Non ho riscontrato nessun difetto ai meccanismi è silenziosa e scorre perfettamente.-Prodotto sicuro è funzionale.Giudizio finale (ottimo)à la prima volta che acquisto questa ventola. Era quello che cercavo e sono pienamente soddisfatto dell’acquisto. La ricomprerei.
