“Our testing is showing that NF-A12x25 G2 PWM fans have roughly 0.8ᵒC better cooling performance and 1.2 dB(A) better sound output compared to the NF-A12x25 PWM fans. This is an incremental performance gain. However, compared to the Silent Wings 4 fans, this is a drastic performance gain with a sound difference of a whopping 4.6 dB(A) for similar performance.Noctua is back in the 120mm fans segment with NF-A12x25 G2 PWM, providing an incremental improvement over the regular NF-A12x25 PWM fans but a substantial difference compared to the performance in the sound department.”

“The best overall: The NF-A12x25 G2 excels in testing. At 1200, 800, and 450 RPM, it outperformed all other fans we tested. There are faster fans, but few others can compete on as many metrics as this one.”

“The new fans are definitely the best you can buy in stores. They’re not cheap, but if you plan on building a PC and forget about the fans for long years, then Noctua is the answer. I won’t hide that we have reviewed and used Noctua fans for over ten years, and we haven’t had a single issue with them.”

“The Noctua NF-A12x25 G2 (PWM) is the most efficient fan we’ve ever tested. It clearly outperforms its predecessor (NF-A12x25 “G1”), as well as the Phanteks T30 and all competing 120 mm fans in the extensive database we’ve built so far. The NF-A12x25 G2 consistently comes out on top, making it an uncompromising choice for the most demanding PC builds.”

“Noctuas neuer NF-A12x25 G2 kann sich im Test als neue Evolutionsstufe beweisen. Wie das größere 140-mm-Modell macht auch der kleine Bruder einen deutlichen Leistungssprung und überzeugt auf ganzer Linie. Lediglich die geringe maximale Drehzahl schränkt das Modell auf die Nutzung im Silent-Bereich ein und kostet ein paar Notenpunkte. ”

“Noctua hat beim NF-A12x25 G2 wirksame Optimierungsmaßnahmen umgesetzt und so tatsächlich einen Fortschritt gegenüber dem Vorgänger erzielt. Wer einen vielseitig nutzbaren Premiumlüfter mit überschaubarer Maximaldrehzahl sucht, ist entsprechend gut bedient. Damit verdient sich der NF-A12x25 G2 unseren Excellent-Hardware-Award.”

“This is a second-generation release of the NF-A12x25 that we reviewed back in 2018 and is by far one of the best fans I have ever used. The G2 takes things to the next level with only a few minor tweaks to the design.”

“Après une longue attente, Noctua frappe fort sur le segment haut de gamme. Avec son NF-A12x25 G2, la marque propose un ventilateur bon à tout faire qui fonctionne particulièrement bien, et ce malgré une vitesse de rotation faible sur le papier si on regarde les anciennes versions ou la concurrence. Pas de doute, voici le ventilateur à avoir si on veut un refroidissement au top avec des nuisances sonores contenues.”

“Through swapping to NF-A12x25 G2, my system is quieter and cooler, just as I wanted. Knowing my Ryzen 7 7800X3D is running ever-so-slightly faster is a welcome bonus too.”
