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

The NF-F12 is the first fan to feature the further optimised second generation of Noctua's famous time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis of rotation to provide even better stabilisation, precision and durability. The NF-F12 is supplied with a Low-Noise Adaptor (L.N.A.) which 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. Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-F12 features an MTBF rating of more than 150,000 hours and comes with a full six years manufacturer warranty. Custom designed for the new Focused Flow frame and to work in tandem with the eleven stator guide vanes, the NF-F12's seven blade Heptaperf impeller has been carefully optimised to achieve a perfect balance between power and quietness.The NF-F12 comes with modular cabling, integrated anti-vibration pads and two speed settings for full flexibility. 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. At the same time, a wide range of advanced aerodynamic design measures, second generation SSO bearings and Noctua's new, custom designed PWM IC for fully automatic control guarantee astounding quietness of operation. 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.

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. Meeting stringent requirements for burst and surge protection, the 24V SP version’s high electrical robustness permits the fan to be used not only in automotive projects but also in other harsh environments with transients from electric motors and other inductive switching loads.The NF-F12 draws only 0.6W, which is less than half many other fans in the same speed range. This not only makes it eco-friendly but also cuts down the electricity bill: Compared to a typical 2W fan, this allows you to save about half the price of the NF-F12 after 5 years of continuous use. 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. 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. This results in reduced blade passing noise and improved airflow and pressure efficiency.

Having received more than 150 awards and recommendations from the international press, Noctua’s NF-F12 has become a proven premium choice for 120mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world.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. This allows the NF-F12 to rival the performance of conventional fans running at much faster speeds.

The industrialPPC 24V SP models use Noctua’s new NE-FD5 high-performance single-phase PWM motor driver IC. Thanks to its excellent commutation efficiency, the NE-FD5 enables the SP versions to achieve exactly the same performance as previous models with three-phase motors. The fan’s voltage-stabilised inrush current suppression provides a smooth power-up and dramatically reduces power line transients that otherwise could affect other electronic components connected to the power line. This makes the fan safe to use in sensitive electronic environments.Ive recently fitted 4 of these fans to my Phanteks Enthoo pro M case 3 on the front as intakes and 1 on the rear as an exhaust. My first impression is there good fans as my idle temps on my components have dropped a few c as have my load temps. on idle my system is near silent I hear my GPU fans over the case fans. Im planning on getting another 2 of these to fit to my Phanteks cpu cooler. The NF-F12 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. Its commanding performance, exhaustive set of features and Noctua's trusted premium quality make it an elite choice for use on air coolers, radiators and other pressure demanding applications. The motor and PCB of the IP67 version are completely cast in a special, highly heat conductive resin that combines thoroughgoing protection and effective motor heat dissipation. Complying with the ingress protection rating IP67, this fan is not only fully dust tight but also completely waterproof up to 1m water depth.
