Features 【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 controller 【LOW RESISTANCE CIRCUIT BOARD】: use high performance all-black circuit board, own small wheel hub, easy to use, strong material and low resistance, will not affect fan performance 【ADHESIVE MOUNTING】: Use thickened sponge glue to attach, have strong adhesion, easy to insert into your computer case, and fix the fan hub firmly in the case 【8-WAY ADJUSTMENT】: Through this hub, the controller can drive up to 8 fans, and the turning potentiometer can adjust the speed of 8 PWM fans at the same time 【EXPANSION FAN CONNECTOR】: Excellent 1 to 8 Splitter 8-Way 4-Pin 3-Pin PWM Fan Power Extension Hub, which provides better power solution for motherboard cooling fan in PC case Specification: Item Type: Cooling Fan Hub Working Voltage: DC 12V Control power: within 60W of a single fan, 8 fans can be supplied 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 control: 4-wire or 3-wire fans with PWM speed control ports can be commonly used. Note that the order of the fan interface is often used Rusting current: 0.015A (standby status) PWM work cycle: 0%~100% PWM frequency: 25 khz Package List: 1 x Cooling Fan Hub Package List 1 x Cooling Fan Hub
