Noctua NF-A14 PWM 12V 1500RPM 140mm Premium Quality Fan

The fully featured NF-A14 PWM is a 140mm fan that is ideal for use on watercooling radiators or as an upgrade for 140mm case fans.

Features

  1. 4-pin PWM and Noctua’s AAO (Advanced Acoustic Optimisation)
  2. Integrated Anti-Vibration Pads
  3. Flow Acceleration Channels
  4. Improved SS02 bearings
  5. Six year warranty

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.

A successor to the award-winning NF-P14

Noctua’s NF-P14 fan has become a default-choice among PC enthusiasts looking for a premium quality quiet 140mm fan. Thanks to its efficient 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 fans 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 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 Adaptor

The 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.

6 years manufacturer’s warranty

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.

Customer Reviews

It's dead silent.

,

It’s dead silent and doesn’t produce any sort of vibration up to 900 rpm. If you are obsessed with quiet PC, I must concede that Noctua has made quite an achievement.

Best fans for 280mm radiators

,

There aren’t many 140mm radiator fans out there but this new Noctua is enough for any 140mm or 280mm radiators in the market.

The skilled team of Computer Engineers at Quiet PC are leagues ahead of everybody else.

I had been designing and constructing PC's for around 10 years, always after, what seemed the impossible. Having spent thousands of pounds with each consecutive pc build and sticking to large brand names, each time getting close to build of my dreams, I came across Quiet PC. Their range of unique and exquisite components really enlightened me. I wrote to them asking if they could build a system. Ellen, the sales manager there, wrote back to me saying it was currently impossible to create the system I had chosen. Several months had passed and I had constructed another PC, which yet again was near my needs, but still not yet perfect. Then Ellen contacted me saying that the system I had specified earlier was now being sold. I instantly wrote back and agreed to purchase. I'm so happy with my purchase too, for the first time in my life, the perfect system was attainable. When it arrived I proudly showed it off to my colleagues and friends. I now no longer will ever build another system again, I will rely upon Quiet PC for all of PC and Component needs. I now have a system which features the most powerful processor currently on the market, 32GB of RAM, and a intel SSD. It is beautiful to behold. The system has no moving parts, and is total silent. 0db silent. And yet it plays games in full HD even without a graphics card at better frame rates than an XBOX 360 or a PS3. It does 4K out of the box, and 3D, 7.1 surround sound and the fully beautiful experience that is Windows 8 64bit. I can leave my PC on in the front room for the foreseeable future and never even notice it. Some times I forget that its on, it's that silent. I have it control lots of devices, such as my home security cameras and my media centre equipment. Valve this week said they where going to be making a living room PC, even with their credentials, I doubt it will be anything like or half as good as the system being offered by Quiet PC. I have ordered other items from Quiet PC and they have always allowed me to return them if they are not up to my requirements. I can't recommend them enough. I will be making further purchases in the future, but it's nice to be able to ring up any of the team at Quiet PC, be it sales or engineering and discuss my purchase before buying it.
