Cougar Vortex Fans: the Secret of Success

Nowadays a lot of hardware developers employ Vortex fans from Cougar in the design of various PC components, including CPU coolers and graphics cards. Such demand is primarily explained by an elaborate approach to the fans' framework construction. Profound testing is not the last thing to contribute to the company's success. Indeed, since the launch date in 2011, Vortex line has been enjoying great popularity throughout the world and, especially, on American and European markets.

Therefore, Cougar has designed unique fan impellers that ensure a balanced correlation between such parameters as static pressure, noise level and airflow. The implementation of aerodynamic elements on the internal part of the frame in combination with the grooves on the impellers are able to promote for an improved airflow focusing; this is achieved due to the acceleration of airflow in edge area.

All Vortex fans are based on a hydrodynamic bearing that provides for the prolonged lifetime and …
