Feature: 1. 8 Fan Ports: PC fan hub can power to 8 fans, expand 8 fan ports and rotate potentiometer to adjust the speed of up to 8 PWM fans at the same time. 2. Widely Compatible: Applicable to 4 pin and 3 pin fans. The total current connected to the fan must not exceed the maximum current value of 17 A to avoid damage to the regulator. 3. Strong Adhesion: Thick adhesive at the bottom for fixing, strong adhesion, easy to install inside the computer case, can fix the fan firmly inside the case. 4. Flexibility: 300mm extension cable for easy connection provides greater flexibility between the motherboard and the cooling fan. 5. PCB Material: PWM case fan splitter is made of PCB material, which is not deformed for long time use, thus ensuring long term stability Specification: Item Type: PWM Fan Hub Material: PCB Number of Fan Holders: 8 Maximum Current: 17A Power Supply Voltage: 12V Power Supply Interface: 6pin (2x3) Interface Speed Range: 0 to Full Speed Fan Port Type: for 3pin 4pin Extension Cable Length: Approx. 300mm / 11.8in. Package List: 1 x PWM Fan Hub1 x User Manual Note: 1.If the fan does not support PWM speed control function, the speed control function is invalid.2.Fan base supports 3Pin and 4Pin fans, PWM fans, all three fans can be adjusted for speed
