Best fans
These are great computer fans, very efficient and very quiet. If you don't care about price or appearance, buy them, because there are no better ones on the market.

The best at a price
Do you hear that? No? That's coz its a noctua fan! Runs dead quiet and my previous issue of vibrations is remedied by the anti vibration 'screw' and pads. To be honest the offset speeds isn't something I can compare, but if the sync up sound has bothered you before, I'm sure they're good. In my opinion they are the absolute best fans you can get, but obviously you pay a premium. They're not the best value, be quiet and fractal are better. You're probably paying for a few decibels better, but if you want absolute best, you pay that premium.

Premium cooling that can't be beat
Works perfectly. Noctua are my go-to for anything air cooling. The amount of air that they can push is amazing, it's like the power of a proper room fan. Moving to these from my previous arctic 212 120mm fans, I've seen ~10c improvements, this is from a 5 fan 120mm setup to a noctua 5 fan setup, with 4 140mm fans (these ones) and a nf-a12x25 G2 at the rear. Noctua aren't cheap, but you definitely get what you pay for.

Whisper quiet and powerful
I read up on these as I wanted a silent PC build. The Fractal case I bought was a little noisy for my taste so decided to replace the in case fans with these and what a difference it made! Temperature wise the CPU dropped around 5 degrees and noise wise they can barely be heard under my desk. They didn't replace the CPU fan directly, so this is purely configuring the ambient air flow so very happy with the results.

Noctua, as you know and expect it
Compared to other fans in it's class it's noise performance is leading with delivering excellent airflow to facilitate the best possible cooling in your rig. As you expect as the fans are able to deliver excellent air flow at lower speed Vs the competition it naturally is quiter at the high noctua quality you expect, of course this comes at a premium but well worth it.

Noctua fans take some beating (in every sense :) )
Noctua fans really are the best. Quiet, reliable, trusted.

Excellent Fans
Set of two, each running at slightly different rpm to avoid noise 'beating' - used with a extra single - to provide three intake fans for my new PC build. Absolutely no vibration, and supremely quiet whilst providing super airflow. Highly recommended.

Silent
Virtually silent below 30% RPM. And, on that setting, nothing in my PC even gets close to 90 degrees, so I just set the fan curve in the BIOS that only ramps up above 90. Very happy. Also, some reviews mentioned some kind of a high pitched noise compared to previous generation - I'm 35 and I can't hear it. 100% recommend.

Best fans and most quiet fans there are.

Noctua, cicha, nieźle wieje, niezniszczalna, brzydka. Fajnie że w pudełku są wszystkie potrzebne dodatki. Niestety bardzo droga.

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.

Die Noctua NF-A14x25 G2-Lüfter gehören sicher nicht zu den günstigsten Optionen, doch sie sind ihr Geld voll und ganz wert. Technisch beeindrucken sie bereits auf dem Papier mit einem maximalen Geräuschpegel von 24,8 Dezibel bei 1.500 U/min, einem hohen statischen Druck von bis zu 2,56 mmH₂O, einer Langlebigkeit von mindestens 150.000 Stunden und einer Herstellergarantie von sechs Jahren. Doch was wirklich zählt, ist die Umsetzung dieser Werte in der Praxis, und hier übertreffen die Lüfter sämtliche Erwartungen. Lieferumfang und Qualität Besonders beeindruckend ist der durchdachte Lieferumfang, der über die zwei Lüfter hinaus je zwei Verlängerungskabel, ein Y-Kabel für den Anschluss beider Lüfter an einem Lüfterport sowie ein Limiter-Kabel enthält, das die maximale Drehzahl auf 1.250 U/min begrenzt und so die Lautstärke auf leise 19,7 Dezibel reduziert. Die Lüfter kommen zudem mit Silikondichtlippen, vibrationsdämpfenden Ecken und einer praktischen Silikonhalterung für ein rundum vibrationsfreies Erlebnis. Diese Details zeigen die hohe Verarbeitungsqualität und den Fokus auf Laufruhe, der sich auch im tatsächlichen Betrieb widerspiegelt. Leistung und Laufruhe im Vergleich Im direkten Vergleich zu den 140mm Silent Wings 4 von be quiet! – ebenfalls exzellente Lüfter – zeigen die A14x25 G2 einen deutlichen Vorteil in der Laufruhe und minimalen Geräuschkulisse, selbst unter Volllast. Während die Silent Wings bereits leise sind, setzen die Noctua-Lüfter in puncto Geräuscharmut nochmals Maßstäbe, was sie ideal für alle macht, die auf höchste Qualität und absolute Ruhe Wert legen. Optik und Fazit Einzige kleine Eigenheit könnte die für Noctua typische Farbgebung sein, die durch das Braun einen eigenen Stil setzt. Für alle, die die außergewöhnliche Leistung und Verarbeitungsqualität schätzen, dürfte dies jedoch kaum ein Manko darstellen. Die A14x25 G2-Lüfter sind ideal für leistungsorientierte Builds, die eine ruhige und zuverlässige Kühlung erfordern, und ich kann sie uneingeschränkt empfehlen. Vorteile: + Außergewöhnlich leise und vibrationsarm + Hochwertige Verarbeitung und umfangreicher Lieferumfang + Beeindruckende Langlebigkeit mit 150.000 Stunden + Vielseitige Anschlussmöglichkeiten (Y-Kabel, Verlängerungskabel, RPM-Limiter) Nachteile: - Bislang keine

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.
