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
