Features 1.EXPANSION FAN CONNECTOR: Excellent 1 to 8 splitter 8 way 4 pin 3 pin PWM fan power expansion hub, providing better power solution for motherboard cooling fan inside PC case 2.8 WAY ADJUSTMENT: Through this hub, the governor can power up to 8 fans, and rotary potentiometer can adjust the speed of 8 PWM fans at the same time 3.WIDE COMPATIBILITY: Suitable for 4 pin 3 pin fans. If the fan does not support the PWM speed control function, the speed control function is invalid. The total power of the connected fan should not exceed 300W, so as not to damage the governor 4.LOW RESISTANCE CIRCUIT BOARD: Adopt high performance all black circuit board, possess small wheel hub, easy to use, strong material and low resistance, does not affect performance of fan 5.GLUE FIXATION: Use thickened sponge glue to fix, possess strong adhesion, can be easily put into your computer case, and firmly fix the fan hub inside the case Specification Item Type: Cooling Fan Hub Working Voltage: DC 12V Control Power: Within 60W of a single fan, can bring 8 fans at the same time, the total power is within 300W (note that the total power also depends on the power of the chassis power supply) PWM Fan Speed Regulation: 4 Wire or 3 wire fans with PWM speed control ports can be used in common use. Note that the fan interface sequence is commonly used Quiescent Current: 0.015A(standby state) PWM Duty Cycle: 0%~100% PWM Frequency: 25khz Package List 1 x Cooling Fan Hub
