NF-A12x25 PWM

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've been using Noctua fans for years in my PC builds. I just upgraded from my old i7-6700K to a Ryzen 3900X, and with the all-core overclocking and a 2080 Super FTW3 I needed some extra cooling in the case and for the CPU. With the standard 3 120mm fans on a NZXT Kraken X72, CPU temps at 4.2GHz/1.2v VCore were way up in the 97C range using the default fan profile. Ramping that up to a higher speed brought temps down to ~93C under Prime95 "Blend" torture tests, I'm not usually happy until it sits in the 60s or 70s. My radiator is mounted in an exhaust position at the top of a Thermaltake Core V71 case with two Noctua 140mm 3000RPM fans as intake in the front and another one in the usual rear exhaust location. With the 140mms running around 600rpm and the default NZXTs wide open, I just could not get it down out of the 90s under load. I replaced the three NZXT fans with 6 of these NF-A12x25 fans and the 3900X will not get above 73C for ~15 minutes with the fans at nearly inaudible levels (~900 RPM). With the fans set to ramp almost linearly up to 100% (2000RPM) at 80C, I now see a max temp of about 83C with the GPU at 100% load with MSI Kombustor, and about 77C with the GPU at idle. It's just not even the same setup anymore. Granted, it needs a fan header hub to support all those fans but the MSI MEG X570 ACE does a great job at controlling all the speeds and keeping things very reasonable now. I had some original NF-A12 fans that were doing OK, but the newer A12x25 blade design appears to have a marked improvement over the previous simple straight-bladed design. These are expensive, but you also don't need as many fans as I use to achieve a significant reduction in noise from your PC. And they work for the case, air and AIO water coolers, etc. Just love these things.

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.

1. Praxiseindruck Ich nutze den Noctua NF-A12x25 Lüfter als Ventilator beim Löten. Der Lüfter lässt sich über PWM präzise steuern, arbeitet sehr leise und liefert dennoch eine hervorragende Luftzirkulation. Selbst unter Last bleibt er angenehm leise und sorgt für stabile Temperaturen. 2. Qualität Die Verarbeitung ist erstklassig: hochwertiges Material, langlebige Lagertechnik und präzise gefertigte Lüfterblätter. Die Kühlleistung ist konstant und zuverlässig, die Montage gestaltet sich einfach und stabil. 3. Positiv / Negativ Positiv: Sehr leise, auch unter Last Hohe Kühlleistung und stabile Temperaturkontrolle Hochwertige Verarbeitung und langlebige Lager PWM-Steuerung für individuelle Anpassung Negativ: Design in Braun/Beige passt nicht zu jedem, rein optisches Manko 4. 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.
