This technology delivers exceptional cooling performance, low noise and a long lifespan of up to 400,000 hours.           Fan-Blade Grooves   Precision-engineered grooves on the fan blades direct and focus air to flow smoothly along the blades for reduced flow separation. This increases fan performance and reduces vortex noise, improving overall acoustics.           Direct-Flow Frame   The angle and curvature of the frame struts are carefully designed to direct and channel airflow in a unidirectional, highly focused stream. This design minimizes turbulence and the focused airflow enhances static pressure.           Dynamic Balance Pre-Calibration   The balance of each fan is manually tuned to minimize inefficiency and ensure optimal performance.           Precise, Flexible PWM Speed Control   An extensive operating range of 250 - 1800 rpm offers the precision and flexibility to maximize cooling performance across various workloads, and the fan automatically turns off when set to 0% PWM duty cycle for an ultralow noise profile when handling lighter workloads.
