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!

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 5 225 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。

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

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!

The quietest fans out there.
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.
