The classic NF-B9 is a long-standing favourite among enthusiast users around the world and helped to found Noctuas reputation as a top-tier manufacturer of premium quality quiet cooling components. The new redux edition reissues this award-winning model in a streamlined package that has been reduced to the essential core: the NF-B9 premium fan. Its industry grade SSO-Bearing bearing and over 150.000 hours MTBF rating make the NF-B9 redux a proven premium choice that provides trusted Noctua quality. The 1600rpm version is ideal for efficient case ventilation or other applications that demand an even balance of performance and quietness.
Noctua's signature Vortex-Control Notches split up trailing edge vortices and thus spread the fan's noise emission over a wider range of frequencies. This measure makes the fan sound more pleasant to the human ear.
