CPU Cooler Heatpipe Single Fan Cooling Fan 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, 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*75mm Product weight: 765g Color: Black Material: PC & Copper Fan size: 120*120*25mm Bearing: hydraulic bearing 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 below 150W CPU for inter 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) Note: Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
