Very efficient and quiet
Used for a low-profile CPU heatsink to replace the original fan, it does the job very well with a noticeable gain in silence!

Quiet case fan 120mm PWM
Overview
Silence is golden
Take your cooling and quietness to the next level with the Noctua NF-A12x25 PWM chromax.black.swap
120mm fan. Featuring an AAO frame, Flow Acceleration Channels and a 0.5mm blade tip gap thanks to Sterrox liquid crystal polymer combined with a high performance metal hub and motor shaft, this versatile model will be suitable for a variety of uses thanks to its exceptional performance.
The PWM version features 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, SSO2 reference bearings and a 6-year manufacturer's warranty.
chromax.black.swap series: Capable of offering a wide range of colours, theNF-A12x25 PWM chromax.black.swap fan can be customised as required using the self-adhesive anti-vibration pads supplied or optional coloured cables. It is the ideal model for users looking for a high-end fan that can be aesthetically customised to match popular colour themes: 100% black, black and white or black and red.

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 20 cm (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. |

Very good fan but...
The Noctua are very good fans but beware of what it says, there is no cable included with it as stated on the site to my surprise, a bit disappointed to have to add 4-pin Y cable behind when I was assured it was included with it.

The case Fan
Simply perfect.
The price may seem high, but the bundle is complete. The quality is obvious when you unpack it.
The fans do their job perfectly even at low rpm, and very quiet. I recommend it.Review automatically translated -

Very efficient and quiet fan!
Very efficient and quiet fan, used to replace two rather noisy and inefficient NZXT fans.
The anti-vibration system works perfectly.
Very happy with my purchase.Review automatically translated
