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 effective4 pin 12CM fan with temperature control, using hydraulic technology and PWM temperature control design, large air volume and quiet.The fan speed will change according to the temperature of the CPU, which is more intelligent and more energy efficient.SNOWMAN 4PIN CPU cooler 6 heatpipe Single fan cooling 12cm fan LGA775 1151 115x 1366 support Intel AMDProduct parameters:Model: MT-6 single fanProduct size: 150*123*75mmProduct weight: 765gColor: Black and WhiteMaterial: PC & CopperFan size: 120*120*25mmBearing: hydraulic bearingSpeed: 900-1400+/-10%Socket: 4 PinsNoise: 18-20 dB(A) muteAir volume: 48 CFM MinVoltage: 12V DCCurrent: 0.32+/-10%APower: 2-4WLife: 50,000 hoursApplication:Support below 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 add 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/FX4Package Contents:1* CPU Cooler Fans1* Installation KitOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
