Noctua NF-A14 PWM 140mm Fan
Product Overview
Conceived for industrial heavy duty applications that require enhanced cooling performance and advanced ingress protection, the NF-A14 industrialPPC (Protected Performance Cooling) is a ruggedised high-speed version of the award-winning retail model. Thanks to the outstanding aerodynamic efficiency of the NF-A14 design and the use of a novel three-phase motor, the industrialPPC version provides superior airflow and pressure capacity while keeping noise levels and power consumption moderate as against comparable high-speed fans. While its fibre-glass reinforced polyamide construction and certified water and dust protection make the NF-A14 industrialPPC suitable for operation in challenging environments, the renowned SSO2 bearing technology guarantees an MTBF of over 150,000hrs. Topped off with Noctua's trusted reliability and six year manufacturer's warranty, the NF-A14 industrialPPC is an ideal choice for highly demanding applications that require superior flow rates and ultimate dependability.

Award-winning NF-A14 design
Having received more than 100 awards and recommendations from the international press, Noctua's NF-A14 has become a proven premium choice for 140mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world.

3000rpm industrialPPC version
Running twice as fast as the 1500rpm retail version, the NF-A14 industrialPPC-3000 provides extreme airflow and pressure performance. Combined with the industrialPPC series’ robust polyamide construction and advanced protection features, this makes the fan ideal for challenging industrial applications.

Three-phase motor design
While most axial fans use single-phase motors with 4 slots, Noctua's industrialPPC fans feature a three-phase design with 6 slots, which provides smoother transitions between the slots and thus allows for even higher running smoothness, further reduced vibrations and unprecedented energy efficiency.

Class-leading energy efficiency
While the standard NF-A14 is one of the most energy efficient 1500rpm 140mm fans on the market, the industrialPPC version's three-phase motor provides a further 10% reduction in power consumption when compared at 2000rpm.

Fibre-glass reinforced polyamide construction
Both the impeller and the frame of Noctua's industrialPPC fans are made entirely from fibre-glass reinforced polyamide. This material can withstand temperatures up to 140°C and makes the fans even more robust and break-proof than Noctua's standard fibre-glass reinforced PBT fans.

Certified IP52 water- and dust protection
Thanks to a special varnish coating that covers the motor and PCB, the NF-A14 industrialPPC complies with the ingress protection rating IP52. This means that it is not only highly dust resistant but also withstands dripping water equivalent to 3mm rainfall per minute.

Flow Acceleration Channels
Designed for pressure demanding applications such as heatsinks and radiators, the Focused Flow™ frame features eleven stator guide vanes that straighten, channel and focus the airflow, which allows the NF-A14 to rival the performance of conventional fans running at much faster speeds.

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.

SSO2 Bearing
The NF-A14 industrialPPC 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 industrialPPC 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 industrialPPC uses Noctua's custom designed NE-FD2 PWM IC for three-phase motors. The NE-FD2 integrates Noctua's proprietary Smooth Commutation Drive (SCD) technology, which suppresses PWM switching noises and thus makes the fan quieter at lower speeds.

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

Customer Reviews
Rated 5 out of 5 by 4 reviewers.
Rated 5 out of 5 by Expensive and OTT but worth it Decided that because they cost less and have a higher RPM these would be a better buy than the slower more expensive IP certified ones as I'm fairly certain if these are in the situation to get wet then I should definitely be more worried about other components within my PC. Noticeable sound when at 1000rpm and loud when over 50% but are keeping my system cool only running at 400rpm at idle on a 280mm radiator. 19 February 2016
Rated 5 out of 5 by The Hurricane In retrospect, complete overkill for my needs but by god it is effective! Not in any way quiet at above half speed, but you shouldn't be expecting it to be, this is the industrial version after all. You will get negative internal case pressure easily using this as a case exhaust fan even at a third the speed it is capable of. 26 September 2015
Rated 5 out of 5 by Great fan Good quality fans and well made.I've bought 4 of them to replace Corsair H110i GT fans however the fans came without long mounting bolts wich was a disappointment consider it's premium price! 24 September 2015
Rated 5 out of 5 by Really high quality fan, a little on the expensive side I bought this fan due to its high airflow, and as expected, this is a really powerful fan! Its fairly quiet, even at max speed (this is probably helped by the rubber mounts on each corner) The only negative that I can see is that its slightly on the expensive side, although thats to be expected with a premium fan. 22 July 2015
