高価だがそれに見合う。
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 225CPU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-ML10BMB ASRock B860i wifiRAM 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。

低速から高速まで不快な音を一切排除
140mmファン特有の「ブーン」という低い風切り音や耳障りな高周波を徹底的に抑え込み、風の音だけがスムーズに通り抜けるような、上質で静かな音響特性を実現しています。

ハードディスクのファン交換で快適性アップ
ハードディスクのファンを交換しましたら、かなりファンの音を低減できました。完全に静かではないですが、気にならない程度となりました。交換してよかったパーツです。

Dropped my CPU temperatures about 1° C from the G1 fan
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.

Absolutely Incredible!
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!

Extremt bra och tysta!
Väldigt dyra fläktar men i min mening värda varenda krona.Jag har 9st av dessa i min lilla hemmaserver och vid vila så snurrar de i 25% av maxvarvtalet och då hörs de inte alls, min ventilation i sovrummet som är nästintill knäpptyst låter mer. Vid 100% varvtal så är fläkten fortfarande knäpptyst i sig, det man hör är bara luften som flyttas och den flyttar galet mycket luft!Självklart låter det rätt mycket när luften flyttas men det är inget störande ljud i min mening och det är egentligen helt onödigt att köra dem på max då de presterar extremt bra redan vid låga varvtal.Om man bara mentalt kan komma förbi prislappen så är de helt klart värda pengarna!

El mejor ventilador para PC
El mejor ventilador que se puede comprar actualmente. Eso si el precio también es muy alto. Muy poco ruido, alto rendimiento y sonido agradable. Acabados impresionantes. El color ya depende de cada uno.
