Noctua NF-B9 PWM Fan 92x92x25mm Bevelled Tips Vortex-Control SSO Bearing

The Noctua NF-B9 PWM is a high-performance cooling fan designed for quiet operation and efficient heat dissipation. It features a 92mm diameter and is ideal for users who prioritize noise reduction without compromising on cooling efficiency. The fan is particularly suited for PC builds, servers, and other systems where thermal management and acoustic comfort are important.

The fan uses beveled blade tips to reduce noise and improve airflow efficiency by minimizing turbulence. Vortex-control notches further enhance this by spreading out noise across a broader frequency range, making the fan quieter during operation. The inclusion of SSO bearing technology ensures long-lasting durability and smooth operation, even under continuous use.

The NF-B9 PWM supports fully automatic speed control via a custom-designed NE-FD1 IC, which integrates Smooth Commutation Drive (SCD) technology for precise performance. It comes with a Low-Noise Adaptor (L.N.A.) that allows users to cap the maximum speed at 1300rpm or set a fixed speed, reducing noise even further in quieter environments.

The fan is compatible with most standard cooling systems and motherboards that support PWM control. Its compact size and efficient design make it suitable for both small form factor builds and larger systems requiring reliable cooling solutions. The 6-year warranty adds to its appeal as a premium product.
