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. Read more 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.

This means that the NF-A12x25 offers excellent performance in both static pressure demanding and airflow demanding applications.

  • It's Noctua
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. ... show more

  • When it comes to a quiet PC fan, there is only one brand that can be trusted
I'd been struggling with the fan noise from my alienware R10 for a few months until I got this to upgrade the liquid cooled radiator fan. The fans which came with the rig are so loud that you feel like you are sitting next to a aftermarket muffler of a straight-piped car. After replacing the liquid cooled radiator fan on top of the case with it, the noise problem is significantly improved, and I can barely hear any fan noise. At first I was hesitated with the purchase, because these fans are not cheap. But now, I think it is the most valuable upgrade to rig. ... show more

  • OMG! What a great fan!
Had purchased a couple of these Noctua fans for a planned upgrade ... still planning ... patiently waiting for video card prices to return to earth. Anyhow. This evening, two of my wife's Phanteks' case fans went out. Since I had the two Noctua's on-hand and we were getting ready to play a game, I grabbed to two Noctua fans and put them in the front of the case to replace the dead/dying Phanteks fans. ... So, I ended up with two Noctua's, one bottom and one center on the front panel and the remaining Phanteks fan in the top slot. ... After rebooting the computer, I can put my hand in front of the computer's front panel and feel the difference in air movement. ... I knew Noctua made great CPU coolers, but I was seriously impressed to be able to "feel" the difference with my hand. ... Impressive Noctua, really impressive, and well done. ... show more

  • Might be the last fans I ever use.
I'll be honest, I've been a Noctua user since my first build and it finally made sense to me why the fans are this color when I got the brown ones on the latest build. Dust. Duh... It's so much less visible with this color. But that's not why we buy them. It is a nice feature though. Cleaning less often is always nice. That said, the only con is they don't offer 140mm versions. They would be that much more quiet and move just a bit more air. Why not? ... show more

  • Good quality moves air
Noctua quality. Excellent airflow. Has a hum at full speed. But is quieter than most fans. Ugly color

  • The loudest part of my PC is now my AIO pump
Replaced the fan on my Corsair H60 for something quieter without a performance cut. This did it. Totally silent at idle, and when it ramps up to max (which it never does, because now my i7-9700 doesn't go past 72°C on a Cinebench benchmark after 10 minutes) it's a little louder than my laptop's fan. I don't even have the low noise adapter on. ... show more

  • Blown away
Wow. I wasn't expecting much but this fan is amazing. I have an old i7-8700K with a Corsair H60 liquid CPU cooler. I was idling at 35C and under full load I was getting temps of 94-95C and with the limit being 100C, that's a bit too high for my taste. After replacing the fan on the radiator with this, my idle temps dropped to 28-29C and at full load while gaming it never gets above 82C or so now. Unbelievable. ... show more
