Feature: 1. High Power: Using sophisticated production technology, the PWM fan hub has high power and long service life. 2. Function: Through this hub, the governor can supply power to up to 8 fans, and the rotating potentiometer can adjust the speed of 8 PWM fans at the same time. 3. Easy Installation: Easy to install, the rubber pad at the bottom of the fan speed controller can be glued to the chassis for fixing. 4. High Quality Materials: Made of high quality PCB materials, the PWM fan hub is sturdy, durable and not easily damaged. 5. Parameter: The power supply voltage is DC12V, the power supply interface is 6pin (2x3) interface, and the maximum current is 17A. Specification: Item Type: PWM Fan Hub Material: PCB Color: Black Product Size: Approx. 42 x 29 x 20mm / 1.7 x 1.1 x 0.8in (Manual Measurement Allows Errors) Power Supply Voltage: DC12V Power Supply Interface: 6pin (2x3) Interface Maximum Current: 17A Number of Fan Seats: 8. Package List: 1 x PWM Fan Hub1 x User Manual Note: Note: The fan base supports 3pin and 4pin fans. If the fan does not support the PWM speed control function, the speed control function is invalid. The total current connected to the fan must not exceed the maximum current value of 17A, so as not to damage the speed controller
