Impeccable
I've had them for 1 year now and the ventilation is much better than before.
I'd recommend it!

120mm PWM silent box fan
Overview
Noctua
Silence is golden
Take cooling and quietness to a new level with the Noctua NF-A12x25 PWM 120 mm fan. This model features an AAO frame, Flow Acceleration Channels and a 0.5 mm blade tip gap thanks to Sterrox liquid crystal polymer combined with a high performance metal hub and motor shaft. Versatile, it will be suitable for various uses thanks to its exceptional performance.
The PWM versionfeatures the proprietary NE-FD1 IC which allows fully automatic speed control via the 4-pin fan connectors. It includes a Low Noise Adaptor (LNA) that caps the maximum speed during PWM drive. It also features SSO2 reference bearings and a 6-year manufacturer's warranty. |
Exclusive PWM IC with SCD The NF-A12x25 features the latest NE-FD1 PWM IC with Smooth Commutation Drive (SCD) technology. By generating less abrupt torque pulses, SCD eliminates the noise associated with PWM switching for quieter fan speeds. |
 |
Extensive wiring options
The first fan cable is a short 20cm (8") cable to minimise space requirements for common applications. The supplied 30cm extension cable will solve any distance problems.
|
 |
Flow Acceleration Channels
The NF-A12x25 impeller is equipped with flow channels on the suction side of the fan. The flow acceleration generated at the tips of the blades creates a more massive, less dispersed suction, thus increasing efficiency.
|
 |
AAO frame
Noctua's AAO(Advanced Acoustic Optimisation) frames are equipped with anti-vibration mounts and benefit from exclusive optimisations to push the limits of performance and silence.
|
 |
Stepped inlet design
Noctua's Stepped Inlet design adds turbulence to the inlet flow, allowing a gradual transition from laminar to turbulent flow. This reduces noise emissions, generates a more massive flow and increases suction power.
|
 |
Microstructured bypass duct
As the blade tips move through a boundary layer influenced by the presence of a Microstructured Inner Surface, the flow separation that takes place at the suction level becomes almost non-existent.
|
 |
Integrated anti-vibration dampers
The integrated anti-vibration mounts, made of extra soft silicone, limit the transmission of vibrations while ensuring perfect compatibility with standard fastening systems.
|
 |
SSO2 Bearing
This is the latest generation of the SSO2 bearing, which is even more optimised. The SSO2 is equipped with a rear magnet closer to the axle for greater precision, durability and stability.
|
 |
6-year manufacturer's warranty
Noctua fans are renowned for their quality and durability. As with all Noctua models, the NF-A12x25 has an MTBF of over 150,000 hours of testing and is backed by a full 6 year manufacturer's warranty.
|
 |
Low Noise Adapter
The NF-A12x25 comes with a Low Noise Adaptator (L.N.A.) that drops the maximum speed from 2000 to 1700 rpm. The L.N.A. is suitable for both fixed speed operation and PWM bridged operation. |

Silence is the order of the day!
Noctua excellence. Quiet and efficient. Well... I would have preferred the Chromax version which will be available soon! After the little brown/beige side, you get used to it. It's even classy in the long run. x)

Great fan
Comes in a sturdy box, this fan exudes quality. Lots of accessories included that I didn't need, but that's a good plus.
LDLC service is really good. Hats off to you!
At this price, you get what you pay for. I've been using it for a while now, and it's really quiet, just what I was looking for.Review automatically translated
