1. Compatible with Intels Dual Core Pentium, Pentium4, and Celeron D for Socket 775. 2. Low-noise 92mm PWM Control fan for automatic control of the fans RPM according to CPU temperature. 3. Optimized heatsink layout composed of pure copper for maximum heatsink efficiency.4. Innovative, patented, and curved heatpipe design for a heat transfer capacity of up to six heatpipes with just three. 5. 0.2mm ultra-slim fins for minimized weight and reduced airflow resistance. 6. Maintains minimum RPM even when Duty signal supplied by M/B is below 30percent.7. Operates in silence by preventing extreme RPM during initial booting.
