Noctua NF-A14x25 G2 PWM Sx2-PP, High-Performance Quiet Fans 2x140mm

Something I did not realize until doing extensive testing for 3-4 weeks after building my new PC last year is that these are wickedly quiet, like, quieter at the same RPMs than the single Noctua that I have on the back of the case and quieter than the Noctua heatsink fan on my CPU. This means that I can set FanControl curves to keep these running a bit higher than expected while remaining completely silent, dump extra air as a response to sharp temp increases before any other fan speeds up. In other words, these are my 'first responders' in my FanControl settings. I never expected the front fans (which are closer to my ear!) to be the absolute quietest part of the build. Unbelievably good engineering from this company, like, stunningly good. I can certainly say these have probably brought me the most happiness per dollar compared to any other component in the PC, if you exclude the GPU... not that that's a real metric or anything.

Noctua is second to none when it comes to the construction of their fans. They blow a lot of air, keep the noise reasonably low, and cool down sweaty components. Noctua have thought of every way to optimize airflow at the quietest decibel level imaginable. I get the lowest temps with their fans compared to anybody else’s. They’re super reliable, even though the color isn’t exactly what most would consider ideal.

-Pricier than it's competitors. However, you definitely get what you paid for in terms of quality and funcitonality -Very quiet fans on all levels of computer (idle, low, medium, high). On idle and low loads, any noise from the fans are immediately drowned out by background noise. On medium and higher loads, the fans start to become audible but barely -Mounting is very straightforward. Fans come with other seals/gaskets depending on it's application on your PC setup. How the fans come out of the box should be good for 70% of most PC applications, but it's great that you have options to customize the fans if need be -Overall, would definitely buy this product again.

I bought 4 (2 packs of 2) of these and paired them with the Noctua 360 AIO. Man what a difference they have made in my rig. My old rig was so loud when it was under even a fairly light load. My system was kept cool but it's much cooler now, much quieter, and I've even overclocked my CPU a bit to improve performance. Highly recommend!!!!

In my Opinion the Noctua NF-A12x25 G2 are the Greatest, Performance, Quiet fans on the Market. They have the power to cool the most powerful components currently on the market while staying some of the quietest fans you can purchase. They come with vibration Pads for the front and rear of the fans, Rubber Mounting Studs, Cable extensions, and a Y-Splitter making for simple installation without having to purchase anything additional. They have only two negative issues In my opinion. The are not available in Reverse Blade configuration, and they do not have an RGB option. So if your looking for awesome Performance, and an ultra quiet PC system look no further.

Super easy to install any way you choose, I went with the rubber plugs for even quieter operation. The fans cool very well and provide a great amount of airflow at all speeds. They're incredibly quiet to the point where I cant tell if my PC is on without looking at it. The "matched" pair is nice as well, avoiding any possibility of beat frequencies. Pair with a solo fan on a 420mm radiator or for the main intakes/exhaust like I did on my H9 flow. Incredible performance out of these fans. Wish I needed more.

Great fans, high quality company, upgraded to the new g2 fans. I'm using this in a pull config for a 420mm rad and fans move air evenly over threw the rad. I used the gasket on the rad side for extra pull. There good noise level I keep them at 20% and they cool good. I have them hooked to a SATA power to 3 4 pin cable with pwm hooked to a Corsair commander core xt.

1. They can be whisper quiet and do a decent job; although, I'd recommend setting a fan curve for optimal balance between airflow during peak CPU utilization and quiet during light workloads. 2. They are effective at airflow and pressure making them a true jack of all trades. 3. Significantly more powerful than the 120mm fans but at the cost of a bit of noise when ramping up but bottom end is still whisper quiet. I'm currently running these in a push config on a water-cooled CPU radiator. Mind you I barely notice these fans even with open back headphones, massively better than the ones that came with the radiator.

Best fans and most quiet fans there are.

quiet and efficient

Quiet, hope it lasts as long as the previous Noctual A-series fans Pretty pricey though

These are amazing! I put these as front intake, rear exhaust and for a push-pull setup on my radiator! They push an incredible amount of air and the noise they make is a “pleasant” experience.

Si quieres tener lo mejor y que sea sin lucecitas, éstos son los mejores ventiladores. No quiero refrigeración líquida, no tenía otra opción para tener la máxima potencia siendo silenciosos y sin tener que poner los ventiladores al máximo ya que no es necesario. Quería el mayor flujo de aire con carga (gaming sobre todo) pero con los ventiladores al 50% como mucho para evitar que parezcan un avión, jaja. Así el procesador y la gráfica los mantengo más frescos. Es una gran inversión pero con una buena torre tienes ya los componentes para muchísimos años. Cuanto menos temperatura tengas, mejor trabaja todo sin que parezca el ordenador una freidora. Mucha gente compra componentes caros sin pensar bien primero en cómo va a ser la ventilación y es un error. Noctua es calidad y lleva muchos años conmigo sin defraudarme. No necesito que sean RGB para nada ya que lo que quiero es ventilación EXTREMA y que sean silenciosos. Hay gente a la que no le gustan los colores marrones pero a mí me encantan ya que conozco de sobra su rendimiento. Aun poniéndolos al máximo, claro que suenan algo porque es lógico con ese tamaño a 1500rpm. Pero la suavidad es lo importante en comparación con otras marcas. Recomiendo su compra sin ninguna duda.
