Feature: 1. PWM Fan. The speed of fan will change according to the temperature of CPU to reduce noise and power consumption. 2. Easy to Install. The fan adopts buckle installation, easy to install and remove. And with 4 pads applied on the feet of the fan, it is anti-vibration. 3. 4 Direct Contact Heat Pipes. With 4 stripes of pure copper heat pipes direct contact with CPU, it improves heat-dissipating performance. 4. Through Fin Technology. The heat pipes are designed to pass though aluminium fins, increasing their contacting area, thus improving heat-dissipating efficiency. 5. Wide Compatibility. It is compatible with Intel LGA 775, 115X, 1136, 1200(Core i3/i5/i9 CPU) and AMD AM4, FM2, FM1, AM3+, AM3, AM2+, AM2. Specification: This RGB CPU Cooler is designed with 4 direct contact heatpipes, plus through fin technology, offering great thermal performance. Besides, the rotating speed of fan will change according to the temperature of CPU, consuming lower power. And it is compatible with multi-platforms.
