Noctua NF-A14x25 G2 PWM, High-Performance Quiet Fan 140mm

I have the meshyfy xl 3 case. My processor is an i9 14900kf. The graphics card is the msi 5090 vanguard. Prior to installing this as a rear exhaust fan I was getting CPU temperature average in a modded cyberpunk of 78C. Without a rear fan. Now the same game is giving me 66C. Yes sounds amazing but most likely due to the extra fan and the amazing performance of this noctura fan. When my current Atmos ninja AIO is ready to be replaced I will also be adding their 420mm AIO to my setup as I am super impressed by the quality and performance of noctura. It's quiet and does the job. Should have bought this a while ago but glad I did now

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.

I've been waiting for these fans for so long, and am happy they've finally been released! ... and they're as good as I expected. They're replacing Thermalright TL-B14 fans on a 280mm rad. The TL-B14s are by no means bad (and admittedly "clones" of Noctua's 120mm fans in a way), but the engineering from Noctua shows: more static pressure at a lower noise. Higher quality. Better mounting and noise profile. You get what you pay for with Noctua fans.

Whisper quiet missing bracket in the box not bothered because used for my case not radiator super quiet fan zero noise.

I like the performance of these fans. I am after mostly quiet but occasional power. The amount of research & development that went into these fans is impressive. I used them to replace my NF-A14s when one of them died (within the six year warranty). I have the same level of system noise (aka none with headphones on) and my coolant temperature is lower; which with modern CPUs and GPUs means more performance. I have my fans set to ramp up @36'c water temperature (summer time) and have 10'c to go, at virtual silence. I bought a spacer: Noctua NA-IS1-14 Sx2; and have used it on one of my 3 140mm radiator fans as space permitted. I've watched a youtube review which said that the fans can perform better with the spacer in this pull scenario with a radiator. Did I mention the six year warranty?

Well I've always been a fan of Noctua fans, hence I bought 6 to replace the fans from my Fractal North XL Case. My whole system comprises of Noctua along with ND-15 Cromax air cooler. These fans keep my whole system so cool and that includes rtx 5090 gpu. Buy with confidence they aren't cheap but the rolls Royce of fans. Just buy them you won't regret it.

Swapped my case to Antec Flux and fit 4x NF-A14x25 G2 PWM Sx2-PP at the same time, 3x at the front and 1 in the rear, used 1 NF-A14x25 for PSU shroud intake, really impressed with how you can't hear these fans under 800 RPM, even at 400 RPM the amount of air they move is impressive, they can be heard once you start increasing the RPM however with the amount of air they move I don't have to have them above 600 RPM. As in Noctua fashion you get a very nice unboxing experience and they come with all the usual accessories you'd expect, one thing to note is by default the fans ship with the radiator rubber gasket preinstalled unlike previous Noctua fans that come with the 4x corners preinstalled so you'll have to swap them over. Expensive when compared to other fans on the market however I'm more than happy with my purchase.

These fans are the pinnacle of quiet efficient cooling.

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.

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!

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

Easy to install plenty of cable length nice and quiet good airflow.
