Description: In total four 6mm pure copper heat pipes, through FIN process, make the heat pipe and fins connect closely, and the heat conduction is smooth. The four heat pipes directly contact the CPU and quickly transmit heat to the heat pipe and fins without resistance, which ensures the ventilation space between fins and a smoother heat conduction. Four bright color lamp beads light up the exclusive nameplate pattern on the top, increase the light effect ornament, block the sintering end of the heat pipe, and increase the integrity. PWM speed control, efficiency and quiet can be calmly faced, 5V magic color lamp beads with soft light fan leaf, results in more than 16 million kinds of color changes. The optical effect can realize the ARGB synchronization of the main board, and can also be adjusted by the controller. Specification: For Intel platform: LGA 775 / 1150 / 1151 / 1155 / 1156 For AMD platform: AM4 / AM3 + / AM3 / AM2 + / AM2 / FM2 + / FM2 / FM1 Bearing Type: hydraulic bearing Fan speed: 900-2300rpm (± 10%) Air volume: 15-36cfm Noise: 20-30.5dba Input voltage: DC 12V Fan interface: PWM 4Pin Optical effect interface: 5V 3pin ARGB pin (the main board ARGB is synchronized, which needs to be supported by the main board) Material: copper aluminum alloy ABS Size Chart: 93x78x126mm/3.66x3.07x4.96inch Package Includes: 1 Piece CPU Cooler Radiator Note: 1.
