Refining our thermal technology and improving on the overall design is a nonstop process. With each generation, the fan blades take on a new shape – allowing us increase airflow and, with the latest improvement, minimize turbulence.
Within the enclosed, blower-style casing, airflow is trapped between the blades – which enters through the intake and leaves through the exhaust. The new design, however, a serrated edge to reduce noise caused by turbulence when spinning at high speeds.
In our efforts to increase airflow and reduce noise, we decided to look outwards – most notably, towards owls. By mimicking the silent, yet high speed flight mechanics of these animals, we improved on our AeroBlade™ design. Like the wingtip of an owl, the edge of our fan was made serrated to allow small packets of air to pass through.
At high speeds, greater turbulence means greater noise. To reduce this from happening, winglets were added to the top and bottom of each fan blade – resulting in even greater stabilization.
The success of the latest evolution in AeroBlade™ 3D Technology was confirmed with a 45%1 increase in airflow over the generic plastic fan2 – all while spinning at more silent speeds.
In addition to increased airflow, noise, caused by turbulence is also reduced.
