CPU er pipe Double Fans ing Fan 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 exqui . 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, 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. Product parameters: Product size: 150*123*103mm Product weight: 877g : Material: PC & Fan size: 120*120*25mm ing: hydraulic bearing Speed: 900-1400+/-10% Socket: 4 pins : 18-20 dB(A) mute volume: 100 CFM Min Voltage: 12V Current: 0.32+/-10%A : 4-6W : 50,000 hours Application: below 150W CPU for inter A1150/1151/1155/1156/1366/775 interface for Core I3/I5/I7/Pentium/Celeron/Xeon.( 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/FX4 Note: shooting and different displays may cause the color of the item in the picture a little different from the real thing.
