Noctua Housing fan nf-a12x25 pwm

The NF-A12x25 is a high-performance, next-generation 120 mm lead that sets new records in terms of silent cooling performance thanks to innovative aerodynamic design measures. It combines trend-setting Noctua technologies such as the AAO (Advanced Acoustic Optimization) frame or Flow Acceleration Channels with an unprecedentedly narrow impeller gap of just 0.5mm. The required manufacturing precision is ensured by the use of the new Sterrox liquid crystal polymer and metal reinforcements on the hub and axle mount.

In keeping with Noctua's A-Series concept, the NF-A12x25 is a real all-rounder, with excellent results in all applications - whether it's low-backlash-driven, low-pressure, low-pressure applications or pressure-sensitive high-drag scenarios how the use goes on coolers and water cooling radiators. The 4-pin PWM version supports fully automatic speed control ?? r PWM connections and comes with a low-noise adapter, which can reduce the maximum speed in PWM operation from 2000 to 1700rpm.

The impeller of the NF-A12x25 is equipped on the suction side with so-called flow acceleration channels. By accelerating the air flow in the critical outer regions of the leaves, suction side vortex shedding is reduced, resulting in higher efficiency and lower turbulence noise.

Noctua's Advanced Acoustic Optimization (AAO) frames feature built-in vibration buffers, a stepped inlet area (Stepped Inlet Design), and an interior microstructure (Inner Surface Microstructures) for even greater performance / noise efficiency.

The NF-A12x25 is equipped with the further optimized second generation of Noctua's proven SSO storage system. For SSO2, the backside magnet sits closer to the axis of the axis, providing even better stabilization, resulting in further improved precision and durability.

The NF-A12x25 comes with a silicone sealing lip that can be used on installation on water cooling radiators and other applications that benefit from a tighter seal. The sealing lip contributes to the damping of minimal vibrations as well as the reduction of leakage currents between the cooler and the radiator for optimum cooling performance.

The NF-A12x25 PWM comes with a (LNA) that reduces the maximum speed from 2000 to 1700rpm. This allows you to either operate the fan at a constant 1700rpm or limit the maximum speed in PWM operation.

While the 20cm short primary cable in typical applications helps to avoid cable clutter, the included 30cm extension provides extra reach for all occasions. Both cables are fully sheathed and a 4-pin Y cable allows you to control a second PWM connector on the same connector.

This housing ermöglicht ter allows the control of the speed by pulse width modulation with the help of a PWM-capable motherboard. As a result, the idler speed is dynamically adapted to the respective operating conditions and unnecessary noise development is avoided.
