          • Made from sturdy high-grade glass-fiber-reinforced thermoplasticpolymer
          • Fan geometry optimized for excellent airflow
          • Aerodynamic thin stator struts reduce noise output
          • Strategic blade notches diffuse noise from blade/stator interaction
          • Trip Wire technology reduces blade turbulence
          • Powerful motor reliably maintains stable speed
          • Low-speed adapter included to reduce speed without need for a fan controller
          • Available in 120mm and 140mm fan sizes
          Venturi High Flow Series

          The Venturi High Flow Series fans, HF-12 and HF-14, are optimized for low-restriction airflow environments, making them an excellent choice for computer case fans, or other low-restriction usage scenarios.

          Designed with a variety of performance-increasing and noise-reducing features, these fans can move an amazing amount of air compared to other fans at the same, minimal noise level.

          The HF-14 comes with two sets of solid vibration-dampening rubber corners: one for standard 140mm fan hole spacing (125mm) and one compatible with the standard 120mm hole spacing (105mm). The Venturi High Flow Series fans are ideal for those looking for a perfect balance between high performance and low noise built from sturdy, high quality materials.

          Key features

          • Featuring true FDB-bearings, providing silent operation coupled with a long lifespan
          • Equipped with a counter-balanced magnet that reduces the axial tension on the bearing
          • Features integrated vibration-dampening corners, made from solid high-quality synthetic rubber
          • Dense, sturdy construction, made from high-grade glass fiber reinforced thermoplasticpolymer
          • Fan geometry is optimized for a ground-breaking airflow, perfect for low-restriction usage scenarios such as computer case ventilation and low-density heatsinks or radiators.
          • Aerodynamically shaped thin stator struts reduce noise and unwanted turbulence
          • Strategically placed notches on the blades further reduce and diffuse any humming noise produced when the blades pass the stator struts
          • The trip wire technology introduces a micro-turbulent layer that combats elements that negatively affect performance, resulting in quieter operation
          • Featuring a powerful motor to maintain a reliable speed and a low-speed adapter for reducing the speed without the use of a fan controller
          • 140mm fans come with an additional set of vibration-dampening corners are included that lends compatibility with 120mm fan mounts (105mm screw spacing). This enables the use of 140mm fans on many CPU coolers.
          • Available in 120mm and 140mm fan sizes
          Venturi High Flow Series

          AIRFLOW WITH TRIP WIRE

          Trip wire technology. Commonly found on airplane wing designs. Introduces a micro-turbulent layer that helps to combat the elements that negatively affect performance. By the time the air reaches the end of the blade. The turbulent area will be smaller than without the presence of a trip wire. Giving a quieter and more efficient environment.

          Venturi High Flow Series
          • A. Smaller turbulent area at the end. Resulting in quieter operation
          • B. Trip wire forces early layer separation

          AIRFLOW WITHOUT TRIP WIRE

          Venturi High Flow Series
          • A. Large turbulent area after the layer separation
          • B. Blade has moved too far away. Air can no longer follow the blade. Layer separation occurs
          Venturi High Flow Series
          Venturi High Flow Series
          • A. Trip wire technology
          • B. Optimized blade and stator design
          • C. Counter-pull magent
          • D. FDB-Bearing

          AIRFLOW WITH OPTIMIZED WING PROFILE

          This is the shape of a typical airplane wing. A wide rounded front and pointed narrow rear. This shape allows the cleanest. Smoothest cut through the air resulting in efficient airflow and minimal turbulence.

          Venturi High Flow Series
          • A. Stator struts are angled perpendicular to the blades. Helping to reduce noise commonly emitted when the blades pass the struts.

          QUIET OPERATION

          Venturi High Flow Series
          • A. Screws only pass through rubber. Not through plastic. Therefore eliminating the prospect of noise derived from rattling when in use.
