Noctua NF-A14x25 G2 PWM, Premium-Quality Quiet 140mm PC Fan, 4-pin (Brown)

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. Combine with a "matched" pair 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. A little on the pricier side, but their performance makes them very, very worth the cost.

Perfect fan for the fractal north xl front intake. Just make sure you remove the rubber gasket or it will make a lot noise due to the distance between the fan and the front panel. It’s a poor design by fractal, not Noctua. These fans are the best if you want the most quiet and performance within their RPM range. Sure there are faster fans that are better at moving air but they will not be as quiet or as efficient within this RPM range. Only con is they are stupidly expensive but they are excellent fans.

Noctua has been making cooling solutions for computers over 20 years, and they're quite good at what they do. The packaging is impeccable (which I should hope for, considering the price premium). Plenty of included accessories reduces the need to purchase additional cables or adapters. These are quiet, extremely well built and engineered, and move copious amounts of air at all fan speeds. I also am a fan of the color, which is a polarizing point for many. I have no doubt these fans will continue on into other builds in the future, which I can't say about fans I've used in the past.

I bought this to use with my NH-C14S heatsink, which included the G1 version of this fan. I then reused that fan to replace a 140 mm fan that was included with my case. This gave me an opportunity to do a direct comparison, which I did using a sustained 117W workload. Ambient was about 25° C and mean, steady-state CPU temperature dropped from 69.7° C to 68.7° C. I didn't find the new fan to be any quieter, at max RPMs, but this matches the results found by hwcooling.net, in their comprehensive review. So, I knew not to expect an improvement, in that regard. The fan is indeed very quiet to a point, but it's certainly not silent at max RPMs. The fan included the usual set of accessories, although I was a little disappointed the gasket didn't have more lip on it, like the one that was included with a NF-A12x25 (G1) fan I bought, earlier this year. The main downside of this fan is the price, but I guess that's how things are going these days. The other significant negative is probably the fact that there are fans that produce higher static pressure, even at the same noise levels. Refer to the review on hwcooling.net, to see which ones. In summary, it's a well-designed, well-built fan that met all my expectations. I expect it will easily last for the life of my machine. I've never had a Noctua fan fail on me.

Definitely the best fans to exist. Very quiet and even hits 1900 RPM at full blast which isn’t too loud. The price is a bit high but overall I say it’s worth it with everything that it comes with. I wish it came in any color but brown, but cosmetics isn’t what I was looking for and it is a sacrifice well made. For context: I have a MSI 5070 Ti Shadow 3x OC GPU with an AMD Ryzen 9 9900X CPU. I used these on the front of my case and it took the temps down 2C. I do AI workloads and game on ultra graphics where it keeps a max of 85F. It put my prebuilt CyberPower PC fans to shame, that’s for sure.

These are essentially silent at low speeds. They come with mounting screws and fan cable extensions. I like the 140mm vs 120 — I feel that it moves more air. Works great!

Great product. Certainly expensive, but also very worth it. I purchased several of these as case fans for a new PC build. Color goes great with a wood-accented case. Installation was easy, box comes with everything needed to daisy-chain. Would buy again

If you are someone that strives for the best quality fans & want to squeeze the most out of your PC then Noctua is the answer. Although the price for these are on the high end when buying PC fans, the material quality & noise level make up for it. I run my fans on Full blast & still don't notice the noise unlike various other brands I've tested. I wanted an improvement on case temperature & GPU temps during gaming & these are the ones that work best with my case (NZXT H9). Under full-load I dropped my GPU temps by around 5C & surprisingly saw a decrease in my CPU temps as well. I eventually plan on having only noctua fans in my system because the performance and power is hard to beat. If you want the best longevity & lowest Temps & have the money to spare, you will not be disappointed.

Silenciosos, mi sistema está bastante fresquito, adoro los colores de noctua. Lo malo es el precio, pero es lo que tiene comprar una marca premium.

Noctua NF-A12x15では静圧風量が足らず、ちょっとした負荷でMB温度やSSD温度が上がりがちだった。 結果、ファン回転数を上げざるを得ず、少し騒音が大きめとなっていた。 Noctua最新世代である、NF-A14x25 G2ならば静圧風量共に期待できると考えての導入。 構成。 CPU Intel Core Ultra 5 225 CPUクーラー Noctua NH-L9i‐17xx ケースファン Noctua NF-A12x15 PWM → NF-A14x25 G2 PWM ケース SilverStone SST-ML10B MB ASRock B860i wifi RAM Crucial DDR5 6000 16GBx2 電源 RGEEK 200W PSU ＋ 12V 20A ACアダプタ SSD Samsung 980Pro 500GB＆2TB 性能等。 A12x15では冷却に不安があった、RGEEK 200W PSUもうまく冷却できているようで安心。 同じファンカーブでも風量静圧ともにA12x15とは雲泥の差のようで、CPU温度-2℃、MB温度-4℃という結果。 騒音値もスマホアプリでの簡易計測ではあるが、負荷時で-3dBとなった。 実際、ファンの風切音が減ったような気がする。 総評。 Arctic P14 MAXと迷ったが、CPUクーラーと統一したかったのと、迷ったらNoctuaということでこれにした。 ファンとしてはかなり高価ではあるものの、パッケージの高級感や実際の性能、Noctuaのファンは今まで壊れたことがない実績から考えると、それに見合うものだと思う。

If I could give the NF-A14x25 G2 1000 stars, I would! This is hands down the best cooling fan I’ve ever used. Sure, the price is a bit higher than other options, but it delivers results that set it apart from the rest. It does an amazing job keeping my PC cool, and honestly, it’s not even that loud pretty impressive! I’ve stuffed my PC with as many of these as I could fit, and I couldn’t be happier with the performance. Absolutely love it!

Noctua fans never disappoint when it comes the performance, noise and build quality. Better air flow and much quieter than the stock fans in my Fractal R5. They're pricey but imo they're worth it.

Installed as an exhaust fan in my PC. Better than my old fan in both noise and air flow.
