Вентилатор 140mm, Noctua NF-A14 PWM, 1500rpm

The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua’s AAO (Advanced Acoustic Optimisation) standard. Its square shape
and 140mm mounting holes (124.5mm spacing) make it ideal for use on
watercooling radiators or as an upgrade for 140mm case fans. Featuring
sophisticated aerodynamic design measures such as Flow Acceleration Channels,
the NF-A14 further improves the renowned quiet cooling performance of
the award-winning NF-P14. The PWM version sports Noctua’s custom
designed NE-FD1 IC
for fully automatic speed control via 4-pin fan headers and comes with a
Low-Noise-Adaptor to reduce the maximum speed during PWM control from
1500rpm to 1200rpm. Its performance-oriented 1500rpm top speed and
comprehensive speed control options make the NF-A14 PWM an elite choice
for users who strive to strike a perfect balance between excellent
cooling capacity and superb quietness of operation, be it on
watercooling radiators, on heatsinks or in case ventilation.

Succeeding the award-winning NF-P14Noctua’s
NF-P14 fan has become a default-choice among PC enthusiasts looking for
a premium quality quiet 140mm fan. Thanks to its thoroughgoing
aerodynamic optimisations, the NF-A14 provides higher static pressure
and an even better airflow/noise ratio than its much acclaimed
predecessor.

Square 140mm frame

The NF-A14’s square 140mm frame with 140mm mounting holes (124.5mm spacing)
makes it a premium grade replacement for common 140mm case fans and
perfect for use on 140mm water cooling radiators, where its square shape
will ensure full coverage and best pressure performance.

Flow Acceleration Channels
The NF-A14 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 DesignNoctua’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 MicrostructuresWith
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 PadsIntegrated
Anti-Vibration Pads made from extra-soft silicone minimise the
transmission of minute vibrations while maintaining full compatibility
with all standard screws and other mounting systems.

SSO2 Bearing
The NF-A14 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.

Metal bearing shell
In order to guarantee the highest possible degree of manufacturing
precision, minimum tolerance and excellent long-term stability, the
NF-A14 sports a CNC milled bearing shell made entirely from brass.

Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NF-A14 PWM uses Noctua’s novel,
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.

Low-Noise AdaptorThe
NF-A14 PWM is supplied with a Low-Noise Adaptor (L.N.A.) that reduces
the maximum fan speed from 1500 to 1200rpm. The L.N.A can be used either
to run the fan at a fixed speed of 1200rpm 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
to connect a second NF-A14 PWM fan to the same PWM fan header for
automatic control.

Noctua fans are renowned for their impeccable quality and outstanding
longevity. Like all Noctua fans, the NF-A14 features an MTBF of more
than 150.000 hours rating and comes with a full 6 years manufacturer’s
warranty.
