6 pure copper heat pipes wear FIN technology. The heat pipe adopts double-row staggered design, the curved part is round and thick, and the top sintering process is exquisite. Increase the fin group, maximize the heat dissipation area, double heat conduction, faster heat dissipation, more effective 4 pin 12CM fan with temperature control, using hydraulic technology and PWM temperature control design, air volume and quiet. The fan speed will change according to the temperature of the CPU, which is more intelligent and more energy efficient. 4PIN CPU cooler 6 heatpipe Single fan cooling 12cm fan LGA775 1151 115x 1366 support AMD Product parameters: Model: MT-6 single fan Product size: 150*123*75mm Product weight: 765g Color: Material: PC & Copper Fan size: 120*120*25mm : hydraulic Speed: 900-1400+/-10% Socket: 4 Pins Noise: 18-20 dB(A) mute Air volume: 48 CFM Min Voltage: 12V DC Current: 0.32+/-10%A Power: 2-4W Life: 50,000 hours Application: Support 150W CPU for LGA1150/1151/1155/1156/1366/775 interface for Core I3/I5/I7/Pentium/Celeron/Xeon.(When installing the CPU heat sink need to assembly base) Fit For AMD FM1/FM2,AM2/AM2+/AM3/AM3+/AM4 For Ryzen/Athlon/Phenom939/940/938,AMDX2/X3/X4/A10/A8/A6/A4/FX8/FX6/FX4 Package Contents: 1* CPU Cooler Fans 1* Installation Kit Only the above package content, other are not included.
