Product Description

NF-A12x25 PWM header



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.

NF-A12x25

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.

NF-A12x25 sterrox

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.

tip

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.

NF-A12x25 hub

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.

This is a great fan for adding airflow to your case or to use against a radiator for a water cooling setup. The fans are very quiet and honestly not audibly noticeable at 1200 RPMs (mind you i am about 6 feet away from my PC).These fans brought my 9800x3d temps down by 6 degrees from my previous fans that came with the AIO. These are also standard sizing and you won't have to worry about it being too thick to fit in your case.The fans come with a decent amount of accessories such as a cable extension, low noise adapter if you don't have PWM control, as well anti-vibration gaskets that go around the entire fan for radiator application or anti vibrations pegs that you can use instead of the included screws.I have been using Noctua fans for the last 12 years and I can honestly say that I have never had a single issue and even till this day my NF F12s are still in use!

Compré dos para meter aire desde el frontal de la caja y después de dos años funcionando ahí siguen haciendo su trabajo sin problemas ni incidencias. Mantienen sus niveles de ruido contenidos.Aún no me he encontrado a nadie hablando mal de la marca. Hasta ahora había probado distintos ventiladores Corsair y Arctic más o menos del mismo rango, sin dudas, el Noctua los supera.Si bien no son los más baratos en este rango, ganan por goleada en desempeño. Además, Noctua destaca por la cuidada presentación de sus productos y los accesorios que incluye.Estos de 125 mm traen tres cables muy útiles y bien rematados y una junta de silicona antivibraciones que sustituye la protección de las esquinas y la amplía a todo el marco para su uso en radiadores de refrigeración líquida u otras ubicaciones que requieran aislamiento hermético contra vibraciones.Además, tienes los tornillos de toda la vida o una opción de soportes antivibración de silicona muy útiles, efectivos y fáciles de usar. Son una especie de "clavos" (también los venden de cabeza plana) que se meten en el lugar del tornillo y se ajustan y fijan tirando de ellos a mano.Los instalé con estos soportes y, aunque tienen una vida limitada por el tipo de material, cuando los revisé hace poco descubrí que siguen manteniendo la fijación correctamente.Cierto es que por su precio puedes pillar dos, o incluso tres de los más económicos, pero merece la pena pagar un poco más porque estos Noctua cumplen muy bien, son silenciosos y suelen tener ciclos de vida útil muy generosos.

Tout d'abord un mot sur le packaging, il est exceptionnel, à la hauteur d'un bijou de chez Cartier et c'est à la limite un peu too much pour un "simple" ventilateur pour PC.Ceci dit, on comprend vite que l'entreprise Autrichienne ne plaisante pas, tout y est, le joint et fixations en caoutchouc anti-vibration, les éventuelles vis, et les nombreux câbles de connexion.Le mieux étant d'oublier autant que possible les vis, le plus difficile dans la pose consiste à ne pas se tromper de sens pour les fixations en caoutchouc, mais avec (ou sans) le schéma de pose on comprend vite.Coté efficacité/bruit c'est effectivement très silencieux et selon le tuning de vos ventilateurs, il peut passer inaperçu, je n'irai pas jusqu'à dire qu'on ne l'entend pas du tout, mais pour ma part son bruit est différent de mon Cooler Master d'origine, un son plus feutré et légèrement plus grave, preuve que l'extraction d'air est efficace, de plus il a visiblement besoin de tourner moins vite pour un résultat équivalent et c'est surtout ce qui le rend plus silencieux, il est efficace même à bas régime.Certes, c'est un produit de qualité qui a un certain coût mais qui fait ce qu'on lui demande, ventiler efficacement et en silence.

This is actually too good for me. I bought two of these to put on the rear and bottom of my Raijintek Styx case. The build has a Tuf Gaming B660m-plus WiFi board and a 12700k CPU and no GPU card. I figured a CPU as hot as this is supposed to be would make keeping the case cool difficult even with my crazy Arctic Liquid Freezer II 240 AIO I also bought and left the stock fans on.Right out of the box these fans are hefty. There's some meanness just in holding onto it. Much heavier than I'm used to, no doubt about it. They exhibit a lot of weight just on the blades themselves. Give it a flick and notice how long it takes to stop. It's not quite a fidget spinner but closer than anything else I've tried that calls itself a computer fan.The cable sleeves are a nice touch. corner Bumpers are nifty. Not too hard to pop them off and install the included gasket thing that you can use to block all air from escaping around the sides (between the corners) (recommended for use on high pressure applications like Radiators). The included and pre-installed bumpers cause a gap of about 1mm all along the sides that some air could escape through otherwise. Another solution is just to remove the bumpers from the corners on the side that you will have against what ever it is this is going on. In theory that'll result in more noise but a tight seal is assured.The anti-vibration mounts are little rubber tubes that you can pull through the screw holes. the longer end goes through the fan all 25mm and sticks out the other hole. The shorter end you pull through the screw hole on your case or what ever. The ends of these are tapered, you pull hard on it until the wide part pops through. I wouldn't use that to mount it on a radiator. I didn't use them on the case either, but some might prefer it. I think this is ideal for a temporary install though. You can pop them back out, hopefully not breaking the tube off in the process and easily reuse elsewhere. These do stick out a ways. If you're gonna use it somewhere there's not room for the little rubber tube to stick out you can cut it off once you have it installed, but doing so will make a future installation using the same mounts more difficult as you no longer have anything to pull on.My setup lets the CPU package have 144 watts at all threads max load, 4.7ghz p, 3.6ghz e. The darn AIO which I have on top pushing air out is so mean it's keeping the whole case cool all by itself. Meanwhile, I can stop the fans on the AIO and these Noctuas are mean enough pushing air into the bottom and back of the case to passively cool the AIO's radiator, lol. My CPU idles around 72f, temp sensors on the Motherboard between 72 and 93f while doing light load tasks like web browsing. My case is cold to the touch.I put one of these on the other side of the radiator from the stock fan, set it to half speed then gave the stock fan a flick with my finger, it wasn't being powered. It got enough force from the Noctua all the way through the thick radiator to keep spinning, with the Noctua at half speed!This is one mean fan! I did find that if I put my ear right up against the back of the case with the rear Noctua spinning, I can hear the blades going by like you can hear if you go behind a box fan and hear if you talk through it. It's a rather obvious and loud pop every time one of those many blades go by. But at anything more than say 5 inches you can't hear that part of the sound at all.I have no trouble hearing these in the Styx case if I turn them above 40 percent but they really move an incredible amount of air even at low speeds, so if you need quiet, these can do it, just use the included LNA adapter or set the curve in the bios or using a third party program like Asus AI Suite III or Fan Ctrl. These are probably a good investment even if you will limit the speed because their pressure and airflow is so great.For my purpose, the cheaper Redux1700 option would have been fine. I put those on another build I did a while back and they work well there and are not noisy.

Update 04-14-2019: The circumstances of my build have changed. I have converted out to an open loop with (2) 480mm x 60mm radiators and in pull only configuration I use the NF-A12x25 PWM fans to handle to air movement. I have two more NF-a12x25 fans as separate exhaust and @ 900rpm on my loop, my 2700x and 2080 Ti are silently cooled. These fans are truly amazing in noise for flow with these thick 60mm radiators, particularly in the 700rpm-1,300rpm range. I can barely hear all 10 of them from 3 feet away @1,200rpm but at 900 they are truly inaudbile and keep the 2080Ti @ 2,115MHz and 43°C in any load indefinitely. For applications where the lowest possible noise for air moved through radiators is required or desired, look no further.I couldn't stand the AIO pump noise from the NZXT Kraken x62 on my Ryzen 2700x build. After listening to a couple of other systems with the EVGA CLC280, Corsair H115, and H150 I determined that my ears are just tuned to pick up water pump noise. So the next step was the best air cooling solution I could find: The Noctua NH-D15 SE-AM4. With my case the stock NF-a15 fans for that heatsink assembly wouldn't clear both the ram and the case side panel. Thanks to some reviews for this fan along with Noctua saying it was a compatible match, I decided to try these fans for the heatsink in order to keep the twin fan capability. I also opted to replace my (7) NF-A14 PWM case fans with (6) NF-A12X25 fans. I was intrigued by the development cycle and the promise of excellent low mid-range to high mid-range rpm pressure and flow rate.These fans deliver in a way the fringes of my hopes dared to imagine possible but didn't actually expect to exist. With the NH-D15 SE-AM4 I obtain the same boost clocks with only a 2c penalty in Prime 95 small FFT or Folding@Home CPU work units vs. the NZXT Kraken x62 with push, pull or push/pull NF-A14 fans. Where the kraken required the fans spun up enough to be audible from 3 feet away and on par (by ear) with the AIO pump noise to achieve the reference level of cooling the NF-A12x25s lose 2c at 950rpm: they are not audible without my ear in direct contact with the case. Best of all, I am running the AMD Ryzen 2700x at 4.1ghz all core under Prime 95 or F@h CPU and hitting 66c worst case scenario and the computer is completely silent at the seating position 3 feet away. This is well within temperature guidelines from AMD, at a significant boost over advertised all core boost clocks that is sustainable indefinitely and while having a total CPU and SOC combined 130 watts of power used. The pure silence and the temps at full load wouldn't be possible any other way. I tried. The Sterrox polymer based NF-A12x25 is a triumph in design and execution whose value is priceless and performance is peerless.
