Rotating at a fast 15,000 RPM, while producing a 21 cubic feet per minute, Jaro's new 40x15mm AG4015 series is claimed to lead the industry in fan conception and performance. With the impeller design, this powerhouse produces high performance. This tightly designed (40x40x15mm) fan provides a static pressure of 0.92inches of water, and maintains low noise levels. The fan is suitable for storage, networking, set-top box, game console, and power applications.When coupled with features like a frequency generator such as a tachometer, rotation detection via alarm, and PWM speed control for power efficiency, the new "Extreme" fan is propelled to the top of its cooling class. Available operating voltages are 5, 12, and 24DC.
