Vortex-Control Notch
Vortex-Control notch columns turbulence at the rear edge of the fan blades is divided into several particle currents, thus distributing the noise emission of the fan over a wider frequency spectrum. This makes the fan's running sound more comfortable for the human ear.
Bevelled Blade Tips
Beveled Blade Tips (beveled Blade Tips) reduce critical rotor-stator interaction and allow a larger blade surface to be combined with excellent smoothness. They thus contribute significantly to the excellent efficiency of the fan.
PWM IC WITH SCD
The fan supports fully automatic speed control via PWM and uses Noctua's specially designed NE-FD1 chip for this purpose. This unique PWM IC integrates Noctua's smooth commutation Drive (SCD) technology, which minimizes PWM switching noise and makes the fan even quieter at low speeds.
Single Sign-on Storage
Noctuas SSO-bearing combines the proven concept of hydrodynamic bearing with an additional magnet that supports the self-stabilization of the rotor axis. Over the years, this technology has become synonymous with superb smoothness and excellent long-term stability.
