Feature: 1. 1 To 8 PWM fan hub: PC fan controller can connect 2Pin, 3Pin, 4Pin fans to solve the problem of insufficient motherboard interface and provide a better power supply solution for the motherboard cooling fan inside the PC case. 2. Function: Power interface 6Pin power supply. The governor can power to 8 fans, and the rotating potentiometer can adjust the speed of up to 8 fans at the same time. The fan base supports 2Pin, 3Pin and 4Pin fans, and the speed of these three fans can be adjusted. 3. Easy to Use: Chassis fan pressure regulator. No driver required, just plug and play. It can be directly powered by 12V power supply, which can reduce the load pressure of the motherboard. 4. Widely Compatible: Works with 2 pin, 4 pin and 3 pin fans. If the fan does not support the PWM speed regulation function, the speed regulation function is invalid. The total current connected to the fan must not exceed the maximum current value of 13A to avoid damage to the governor. 5. Space Saving: 8 way splitter 12V speed controller. The rotating switch with 30cm cable can be installed anywhere in the PC case. Comes with double sided tape to securely hold the governor inside the chassis.
