The NF-B9 fan is a class, ultra-quiet cooling system of the highest level. It has long been used and appreciated by fans around the world, winning many tests and awards and prizes. This model has contributed greatly to the current reputation and position of the Noctua brand in the world. Night releases the NF-B9 model in the new Redux series. The NF-B9 Redux-1600 PWM is nothing but the well-known, proven and multi-rewarded NF-B9, but with a more affordable pricing package. The fan itself is the same product of the premium series, only the additional equipment has been reduced. A top class SSO bearing, Noctua patents used, a lifespan of over 150,000 hours and a full 6-year manufacturer's warranty means the NF-B9 Redux is a tried-and-tested high-end cooling at an attractive price, backed by Noctua's trust and quality. 1600 revs. ./min version with automatic PWM regulation (PWM IC NE-FD1 system) is ideal to effectively ventilate the case or other elements and ensure the ideal balance between high cooling efficiency and low noise level in all circumstances. At the same time, Noctua sold all accessories (mounts, discounts, extensions, pins, etc.) as separate products that can be filled and adapted to the Redux series at any time. Proven NF-B9 Design Thousands of silent cooling enthusiasts around the world are loyal to the Nok NF-B9 for its impressive silence, perfect performance and unmatched quality. Redux The Redux range of products is some of the most popular and award-winning models in the most affordable packages (the fan is the same but with less extras) Vortex-Control NotchesSpecial notches on the side of the blade separate the finned centrifuge from several smaller vortices. This spreads the noise over a wider frequency range and is therefore thought to be less taxing on the human ear. Velled Blade Tipship at the shoulder ends increases the distance between the tip of the blade and the frame where the RPM is highest, thereby reducing the critical rotor-stator interaction. ) with ultra low power. Most conventional PWM fans have square-wave waveforms that cause sudden pulses of torque, which is a "cyclic" that is primarily heard when the rotation slows down. Thanks to the NE-FD1 system, signals grow more slowly and are softer. Thus, the "cyclicality" is effectively suppressed. System NE-FD1 that work culture is different from competing PWM fans, especially at low speed. An additional advantage of this arrangement is that the fan.SS O-BearingŁożyska SSO has significantly reduced its power, successfully passed the test of time and passed the exam of silence enthusiasts and industrial customers, preserving its original parameters and working culture after a long period of use. SSO - a combination of hydrodynamic bearings and an additional magnet that helps stabilize the rotor axis.
