Noctua NF-A14 FLX 12V 1200RPM 140mm Premium Quality Fan

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

Features

  1. 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 FLX version provides 1200/1050/900rpm speed settings via the supplied Low-Noise Adaptors in order to provide full flexibility in fine-tuning the fan for maximum ventilation performance or near-silent operation. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.

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.

Smooth Commutation Drive 2

The latest version of Noctua’s advanced Smooth Commutation Drive system ensures superb running smoothness by eliminating torque variations and switching noises. This makes the NF-A14 remarkably quiet even at very close distances.

3 Speed Settings for full flexibility

Providing 1200, 1050 and 900 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adaptors, the NF-A14 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness.

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 the supplied 3 to 4 pin adaptor allows you to connect the fan directly to the power supply.

Ultra-Low Power Consumption

Despite its improved performance, the NF-A14 FLX consumes only 0.96 Watts of power, which amounts to a reduction of about 20% as compared to its predecessor. This doesn’t only make it eco-friendly but also helps to cut down the electricity bill!

6 years manufacturers 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.

Top Ultra-Quiet 140mm fans

Top Quality Service and Product

I purchased this fanless Media Centre PC or HTPC from Quiet PC as I wanted to reduce the amount of noise my previous media centre produced with all the fans and it was approaching it's end of life. I didn't know these guys existed until a quick google search presented them to me. At first the price of the product, I thought was is quiet high, and I usually like to build my PC's from scratch. But as I'm getting older and less patient to fiddle with thermal paste, I found this purchase and the whole experience well worth it. The PC itself is as you would expect; COMPLETELY quiet to the point I thought it was faulty!! That's how good it is. Now the buzz from the TV is the only annoying thing I hear (my next project!!). As to the company, Quiet PC, I was reluctant at first since I've never used them before and as I mentioned I prefer to do my own PC builds so I know what has gone into the machine, can ensure nothing is missing and is done properly. I had been burnt in the past, with companies that don't give you the manuals, drivers, spares, cables, etc... and skimp on the screws when putting together. However I was pleasantly surprised that the product was assembled to an extremely high standard (and yes I checked it thoroughly). Everything secured and cables neatly tied together appropriately. All manuals, accessories and spares (even the box!) was sent with the product. Any future upgrades or changes means I don't have mess about finding screws. So this is a big plus for me and shows how professional Quiet PC is. PC was delivered on time as they said it would be and packaged very safely. Therefore I have no hesitation to recommend these guys to anyone who is looking for that top end noiseless PC.
