Features Application for Intel P4 478 Prescott FMB1 2.8GHz and higher required system airflow Low cost LSV (Ultra Low Speed at Low Voltage) Fan

Detail Information
LSV (Ultra Low Speed at Low Voltage) Fan The standard fan speed vs. input voltage curve is almost a linear relation, like the blue line in the picture. For example, the fan speed of a 70 x 70 x 20 mm fan at 12V is 6000 RPM; its 3000 RPM at 6V. When we use this fan on a motherboard with PWM fan speed controlled function, the hardware monitor detect the system is idle, then supply 6V to the fan, the fan speed is 3000 RPM, but we dont need a high speed (3000 RPM) and louder fan in idle mode, because the CPU temperature is so low. How we can get a quiet system in idle mode and cool system in stress mode? The answer is LSV technology. The LSV fan provide a non-linear fan speed vs. input voltage curve, like the red line in the picture. At 12V (Stress mode), it provide the same cooling capability (6000 RPM), at 6V (Idle mode), the fan speed is only 1500 RPM!! Now, you can enjoy the quiet and cool system with LSV technology.
