The NF-A12X15 is a high quality, quiet Noctua fan in 120mm format that meets Noctua's AAO (Advanced Acoustic Optimisation) standard. The NF-A12X15 features the latest technological advances in aerodynamics, including Flow Acceleration Channels.
The NF-A12X15 is a high-quality, quiet Noctua fan in 120mm format that meets Noctua's AAO (Advanced Acoustic Optimisation) standard and is 15mm thick instead of the traditional 25mm. Featuring the latest aerodynamic technology, including Flow Acceleration Channels
, the NF-A12X15 takes the cooling performance for which they are famous to the next level.
The PWM versionfeatures the proprietary NE-FD1 IC that allows fully automatic speed adjustment via the 4-pin fan connectors. It includes a Low Noise Adaptor (LNA) that caps the maximum speed during PWM drive. The NF-A12X15's amazing discretion, the presence of SSO2 reference bearings and Noctua's guaranteed quality level make it the ideal fan for the most demanding users.
Exclusive PWM IC with SCD
The NF-A12X15 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-A12X15 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.
Inner Surface Microstructures
As the blade tips move in a boundary layer influenced by the presence of an Inner Surface Microstructure, 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-A12X15 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-A12X15 comes with a Low Noise Adaptator (L.N.A.) that lowers the maximum speed from 1850 to 1400rpm. The L.N.A. is suitable for both fixed speed operation and PWM clamped operation.
I think this is the case with all fans, but especially small ones like this. If you use it to PULL (not push) air through a perforated grille, there's a fair amount of noise/whirring (regardless of rpm).
The solution is to move it away from the grid by at least 0.5cm, which is not easy, especially as it kills the point of the small size.
You have been warned. It's not necessarily noctua's fault, but the problem is there.

Perfection...
Easy to install
The colour can be a hindrance to many, but if you have a minimum of RGB in your case, it doesn't bother you at all, on the contrary, it gives a very special look.
The accessory kit is very complete.
Bought a venti-rad and later a fan, this brand is simply excellent...
I was missing fan ports on my motherboard...
Well, thanks to Noctua, this is not a problem, they provide :
Y cable (connects two fans on one cable)
Cable extension (handy after a Y to store your cables properly)
Traditional cable
Low Noise cable (limits the maximum speed of the fans for noise)
No need to recommend anything...
Mounting is done with rubber pads, or screws, also provided, I recommend the pads...
Whether it's the noise or the mounting:
The assembly is super easy, and they also allow you to change the fan location in 10 seconds, and without tools. The manual is detailed and clear.
The package is abusively provided... In short
About ventilation...
Some do RGB, some do efficient, and some do silent.
Noctua is efficient, silent and complete... What more can you ask for?

Good flow, but noisy
The airflow, even at 1000rpm is really good and far superior to other 120mm fans from other brands.
But around 1500rpm it gets really noisy (higher than a gamer graphics card) and at 2000rpm the noise becomes unbearable.
When properly installed, it does not generate audible vibrations.
Expect to pick them up at 1500 RPM

Muffler
Used to ventilate my case more efficiently after the beast's power increase. Fulfilled its function perfectly, it silently keeps my case cool even in gaming mode.
