The NF-A12x25 is a highly optimised next-generation 120mm fan that integrates Noctua’s latest innovations in aerodynamic engineering in order to achieve an unprecedented level of quiet cooling performance. It takes state-of-the-art technologies such as the AAO (Advanced Acoustic Optimisation) frame or Flow Acceleration Channels and combines them with a record tight tip clearance of only 0.5mm, which is made possible by using the novel Sterrox® liquid-crystal polymer (LCP) compound as well as a metal-reinforced motor hub and axis for ultimate precision. Following the approach of Noctua’s A-series, the NF-A12x25 is a true all-rounder that yields superb results in all types of usage, regardless of whether it’s in low-impedance, airflow-oriented applications such as case cooling, or high-impedance, pressure-demanding scenarios such as on heatsinks and watercooling radiators. The 3-pin FLX version provides 2000/1700/1350rpm speed settings via the supplied Low-Noise Adaptors so as to give full flexibility in configuring the fan for maximum cooling capacity or near-silent acoustics. Topped off with exceptional running smoothness, Noctua’s reference-class SSO2 bearing, a rich bundle of accessories and 6-year manufacturer’s warranty, the NF-A12x25 is a premium-quality product through and through. Its superior efficiency, cutting-edge construction and pioneering materials make it an elite choice for the most discerning demands.

Great option for a case fan 7/27/2020 3:05:41 PM

Pros: - Quiet, even at high speeds
- Comes with dampeners and rubber mounts
- No RGB

Cons: - Higher priced
- Color scheme
- No RGB

Overall Review: If you're looking for a no-frills case fan that's reliable and effective, this is a great option. This is the same fan on the NH-U12S, and I see why Noctua is sought after for the quality and cooling efficiency. I didn't realize that Chromax existed at the time of purchase, but I'm happy having this in my rig. I did purchase the white Chromax heatsink cover, and that's made the two-tone-tan-fans more tolerable to see through the glass panel.

Keeping this until it fails.

Pricey, but dead quiet, pushes a lot of air, comes with a number of adapters 6/27/2020 2:13:01 PM

It's a great exhaust fan, too!! 6/10/2020 11:39:31 PM

Pros: everything, wonderfully packaged with many accessories and nicely written manual.

Cons: Expensive

Overall Review: I had a dual SLI rtx 2080ti build that ran crazy, crazy hot. like 84c with all fans at 100%. Under load with all the fnas going my build sounded like a 747 jet. My case had premium large intake fans and a mesh front. But the exhaust fan was a flimsy stock fan. But how important are exhaust fans anyway? Doesn't convection do half the work anyway? Well I figured it wouldn't hurt to put a premium fan in for exhaust, so in goes the NF-A12x25. Man, what a difference - max temps were in low 70's and even 60's, and thi is under full, sustained load (gpu rendering). the fan speed on the cards, formerlly 100% under full load, now in the low 60%. Completely changed how my rendering machine performs. So happy with my purchase.

Turns out there are 5V and 12V Noctua fans.... 5/21/2020 1:21:55 AM

Pros: Good Quality Fan

Cons: Seems useless? A PWM fan that plugs into your USB ports but NOT your PWM motherboard fan headers!?

Overall Review: Did not realize this fan was a USB fan not a motherboard fan. Not really sure what the point of this fan is since I can't plug it into my motherboard.... would have been nicer to be warned about the 5V implication on the product page rather than from the instruction manual upon opening it!
