15mm slim design
Having a thickness of only 15mm, the NF-A12x15 is much slimmer than standard
120x25mm fans. This makes it ideal for typical slim fan applications such as
low-profile CPU coolers as well as for freeing up space by replacing standard
120x25mm fans on tower coolers, radiators or in PC cases.
Metal-reinforced motor hub
With many larger-diameter slim fan designs, the shorter axis and bearing lead
to a reduced running stability and lifespan. The NF-A12x15 uses a
metal-reinforced motor hub, a measure typically found in high-speed industrial
fans, in order to guarantee Noctuas signature stability and longevity.
Flow Acceleration Channels
The NF-A12x15 impeller features suction side Flow Acceleration Channels. By
speeding up the airflow at the crucial outer blade regions, this measure reduces
suction side flow separation and thus leads to better efficiency and lower
vortex noise.
AAO frame
Noctua's AAO (Advanced Acoustic Optimisation) frames feature integrated
anti-vibration pads as well as Noctua's proprietary Stepped Inlet Design and
Inner Surface Microstructures, both of which further refine the fan's
performance/noise efficiency.
Stepped Inlet Design
Noctua's Stepped Inlet Design adds turbulence to the influx in order to
facilitate the transition from laminar flow to turbulent flow, which reduces
tonal intake noise, improves flow attachment and increases suction capacity,
especially in space-restricted environments.
Inner Surface Microstructures
With the tips of the fan blades ploughing through the boundary layer created
by the Inner Surface Microstructures, flow separation from the suction side of
the blades is significantly suppressed, which results in reduced blade passing
noise and improved airflow and pressure efficiency.
Integrated Anti-Vibration Pads
Integrated Anti-Vibration Pads made from extra-soft silicone minimise the
transmission of minute vibrations while maintaining full compatibility with all
standard mounting systems and fan clips used on heatsinks.
Custom-designed PWM IC with SCD
Supporting fully automatic PWM speed control, the fan uses Noctua's
custom-designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD)
technology. By providing smoother torque impulses, SCD suppresses PWM switching
noises and thus makes the fan quieter at low speeds.
Stops at 0% PWM
When the fan is set to 0% PWM duty cycle by the motherboard or PWM fan
controller, it will stop. This makes it ideal for creating setups with
semi-passive cooling that automatically turn the fans off and thus run
completely silent at idle if thermals allow.
Low-Noise Adaptor
The NF-A12x15 PWM is supplied with a (L.N.A.) that reduces the maximum fan
speed from 1850 to 1400rpm. The L.N.A. can be used either to run the fan at a
fixed speed of 1400rpm or to cap the maximum speed when using automatic PWM
control.
Extensive cabling options
The fan's short 20cm primary cable minimises cable clutter in typical
applications while the supplied 30cm extension provides extended reach when
necessary. Both cables are fully sleeved and a 4-pin y-cable allows the
connection of a second fan to the same PWM fan header for automatic control.
SSO2 bearing
The NF-A12x15 features the further optimised second generation of Noctua's
renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer
to the axis to provide even better stabilisation, precision and durability.
6-year manufacturers warranty
Noctua fans are renowned for their impeccable quality and outstanding
longevity. Like all Noctua fans, the NF-A12x15 features an MTTF of more than
150.000 hours rating and comes with a full 6-year manufacturers
warranty.
