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.
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.
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.
Stator struts are angled perpendicular to the blades. Helping to reduce noise commonly emitted when the blades pass the struts.
