Featuring a 4-pin PWM connector for precise speed control up to 2000 RPM, it boasts a remarkable lifespan exceeding 150,000 hours. Designed for demanding PC builds, radiators, and AIO coolers, it includes anti-vibration mounts and accessories for a professional, quiet, and durable cooling solution.

## Description

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. Scope of delivery NA-RC14 Low-Noise Adaptor (L.N.A) NA-YC1 4-pin PWM y-cable NA-EC1 30cm extension cable 4x NA-AV2 anti-vibration mounts NA-AVG1 anti-vibration gasket for water cooling radiators Fan screws 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.

Review: 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.
Review: Silent but Violent , in a good way! - incredible fan! looks great , easy to install and it comes with every possible connector you could need , my pc was instantly cooler during gaming compared to the stock fans which gained me performance of the gpu and cpu increasing my benchmark tests .

## Questions & Answers

**Q: Will this be available in black in the future?**
A: yes - we're working on it. Unfortunately the fans material is rather delicate. A simple colour change is not possible - however we're hoping to launch the black NF-A12x25 PWM in Q1/2019.

**Q: wheres the sterrox 140mm version?**
A: we hope to release it by the end of next year.

**Q: can I replace an Antec 120 mm case fan with this?**
A: Yes, as long as they standard 120 mm fan mounts.

**Q: Can this be used to replace fan on h50 cooler, (corsair cooling hydro series cwch50-1 120mm high performance cpu cooler) - will it improve cooling?**
A: It can be used to replace the fans on it, and it will improve cooling. It'll also be much quieter.

### ⭐⭐⭐⭐⭐ README: Alienware ACT1250 TOWER
*by M***. on April 30, 2026*

Be careful with the alienware ACT1250 tower. I have added 5 of these two this Alienware tower, replacing the four existing ones and adding one extra on the front. Now the system is so much quieter that it's actually lower than the volume of my TV under heavy load under performance mode and I can actually game on it now! The system also runs noticeably cooler than with the stock fans. While I did not yet replace the Nvidia GPU fans, they run noticeably quieter and those are the only fans that you can really barely hear. These are the best fans that I have ever used and I am very happy with my purchase! WARNING: IF ADDING AN ADDITIONAL FAN ON THIS MODEL OR OTHER ALIENWARE TOWER PCS, DO NOT CONNECT A SPLITTER TO THE FRONT (SYSTEM2) FAN AS IT WILL CAUSE A FAN ERROR ON STARTUP. INSTEAD, CONNECT A SPLITTER TO ONE OF THE TOP FANS WHICH ARE CONNECTED TO THE CPU PUMP AND THE SYSTEM WILL THEN BOOT UP NORMALLY. - YOU CAN STILL CONNECT AN EXTENSION CABLE TO THE FRONT FAN TO MAKE IT EASIER TO PLUG IN ALTHOUGH.
