The Cooljag Falcon 4 Quad Heatpipe PWM CPU Cooler is designed specifically for the new Socket LGA 1366 to cool the new Intel Core i7 processors. Four copper heatpipes pull heat away from the pure copper base to a large array of angled fins cooled by a quiet, integrated 80 mm fan. The PWM connector allows your motherboard to throttle the fan speed from 2500 RPM all the way down to a dawdling 900 RPM to keep your processor cool without hurting your ears.
