Noctua NF-A14x25r G2 Fan Review: TOP Performance!

The fresh Noctua NH-D15 G2 cooler uses the new fans from this brand, with model number NF-A14x25r G2. Before the G2’s review, I though to look at the new fan, and check its performance. The results, are nothing less but amazing, as you will soon find out.

With the release of the NH-D15 G2, Noctua also introduced its new fan, the NF-A14x25r G2. It might have a max speed similar to the Noctua NF-A15 HS-PWM that the NH-D15 G1 used, but it outperforms every aspect. Moreover, the new fan has normal dimensions, 140x140mm, while the older model measures 140x150mm. The noise output is slightly higher in the latest model, according to Noctua’s measurements (24.8 dBA vs. 24.6 dBA), and the bearing remains the same, SSO2 type.

A note: the NH-D15 G1 uses the NF-A15 High-Speed version, not the plain one, which is restricted to 1200 RPM. Back to the G2 fan, Noctua states that it is a good upgrade for its existing coolers, and I second that, given that its performance is superior. The only problem is that at 40 dollars per fan, you will need 80 dollars to replace both fans on a previous-generation Noctua cooler. Some could argue that you can get a very good air-cooler or even a decent AIO with this amount.

  1. Does this fan currently only support the newly launched air coolers?
    Can the current mounting screw holes be properly installed on radiators or other positions?

  2. The weak 1500 RPM limit prevents it from being the best 140mm fan IMO

    At low RPM, the top 10 fans will likely perform the same in real world as long there’s no weird motor noise. And that’s pretty much the only thing this fan has to offer. P14 Max already offers this PLUS the ability to scale up to compete against high raw perf fans like Noctua Industrial 3000 RPM—-it’s practically like the Phanteks T30 but in 140mm. P14 Max is still the 140mm fan to beat. I hope Noctua release a higher RPM version to justify the high price.

  3. We always wait the test of the fastest 140mm fan for a versus to the Super Flower Megacool. You have news about Noctua for the nf-a14 industrialppc-3000 pwm ??? Couple month ago you said your contact don’t reply and you will ask again.

      1. In worst case I think for that fan only, it worth that you buy it for the review. I think for that 140mm chart, that fan is a huge missing, because everyone know it was the best performer since a long time. There no others like that one excepted maybe Delta server fan in 38mm but no gamer buy this versus in old time like 2005.

  4. Please send me a solid-works 3D model file for the NF-A6X25 PWM FAN.
    Please let me know if the model is available or send it in a .step file format or any compatible format that is available.
