Noctua NF-A12x25 PWM, Premium Quiet Fan, 4-Pin (120mm, Brown)

These fans are excellent quality—so glad I purchased these. Replaced my default dell fans and these noctuas just really push as much airflow at less rpm and less noise—exactly what I wanted.

I really want to recommend these fans, cause they are so quiet, and they cool my pc so SO effectivly and efficently with the perfomace just being outstanding and the color leaves such an accident that I love personally and its SO SO easy to install with the cable extentions HOWEVER, they are so expensive compared to buying some other coolers for packs of 5 and 3x less the price. Id only reccomend this if your planning on running a crazy ahh build like me, or if you just want a real quiet pc. My only flaw with the the product isnt really the fans, but the extensions that it comes with, they suck. They work for that they are suppost to do, but the damn thing is so short and hard to bend that it kinda defeats the purpose. Besides that, for me, a little expensive, but so worth it

I just built my screaming Ryzen9 beast of a PC with a dual 120mm Corsair AIO. I foolishly figured I could cool the volcano that is Ryzen9 with minimal noise on a dual radiator. Not only could I still hear a slight whooosh from the stock Corsair fans at their lowest controllable PWM speed, but the CPU temps floated at 47-52C idle. I tuned up my fan curves to keep things relatively quiet, but anything over 400rpm on the stock fans was audible. Worse yet, when I blasted the CPU with some full load tests, the case damn near took off and flew out of the room. Temps settled at a max 72C, but the fan noise was punishing. It is rare that I will ever get a full 24core load like that, but... I still have to know the limits of my system, right? Annoyed... I hit Youtube. Linus always uses Noctua fans and I kind of figured that was just product placement, not really performance based. How much better could Noctua fans really be...? The Amazon reviews just seemed like an exercise in cognitive bias: "Well I paid $100 to swap all my fans to Noctua, so they must be better... duh!" I've been building PCs for 20 years and I have always tried to stay away from 120mm fans in favor of larger 140mm (or even 200mm when my cases allowed). Bigger fan = slower speed & less noise for the same amount of air. At least, so I thought...I swapped the two front 120mm fans on the AIO for these glorious NF-A12's and I was shocked at the difference. SHOCKED I TELL YOU! Before I modified any of my fan curves, I noticed the idle temp average dropped about 2C--no tuning changes, just the new fans. However, that was running the AIO fans in the 400RPM range. I played with the PWM and discovered that anything under 1000RPM these A12's are pretty much inaudible. Therefore, I picked my idle setting up to ~800RPM. I can't hear a damn thing sitting at my desk, BUT... my idle temps are down to 38-42C. All I hear is the gentle whine of the AIO pump on its lowest setting. Seriously, its absolutely amazing how quiet these fans are. I honestly got down on my hands and knees to figure out if the fans were even spinning! Not until I had my ear 6" from the case could I hear anything. Fantastic. I swapped my top exhaust fan for a NF-F12, which is also pretty quiet, but I wish I had spent the extra $10 for another A12. This is not only because the A12's are even quieter, but their minimum PWM setting seems to be closer to 20% and I can't seem to control the F12's with less than 36%. For me this is fine because at anything below 50%, the F12 is also basically inaudible. However, if I was trying to truly build a ZERO noise box, I would want the lowest minimum duty cycle possible on the fans. The short story is this... I am a full Noctua convert now. I will NEVER build a PC with anything but A12's--until Noctua comes out will something better! I hate the color, but love the performance. I was really considering dropping down to a Ryzen7 just because I didn't like the high idle temps I got with fans tuned down to a tolerable whine, but not anymore! Quieter rig and 8C lower idle temps? Yes please! These fans are so worth the $30 each, it sickens me.

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: Noise Right 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.

Se você procura algo durável, que ventila mesmo sem fazer ruido, pensa em algo bom, é esse Fan.... Vai lá, compra sem medo!!!

Excelente en todos los aspectos. Ofrece un rendimiento sobresaliente, manteniendo un nivel de ruido muy bajo incluso a altas revoluciones. La calidad de los materiales y la construcción es claramente premium, y el control PWM permite un ajuste preciso según las necesidades del sistema. Aunque su precio es elevado, la calidad y el silencio que ofrece lo justifican plenamente.

Installed them on a radiator they keep the CPU much cooler, AND they’re much quieter than the ones originally came with it! No humming or loud noise even when they’re at high speeds, and at normal CPU usage you can barely hear them. These fans lowered my CPU’s temps by around 10-15c, I didn’t expect them to be that much better from the previous ones.

Zusammenfassung Der Noctua NF-A12x25 PWM ist ein hochwertiger, leiser und leistungsstarker 120 mm-Lüfter. Top Kühlleistung, langlebig und zuverlässig – klare Empfehlung. ⭐⭐⭐⭐⭐

I was having a big cooling issue with my PC — my GPU kept shutting down because of heat. I replaced two of my old fans with these Noctua fans, and the temperature dropped a lot almost immediately. Now I can game without any problems at all. They’re super quiet, very effective, and easy to install. The quality feels premium, and airflow is excellent. I’m honestly impressed and plan to buy more to replace all the fans in my case.
