Features: 1.Expansion Fan Connector: Excellent 1 to 8 splitter 8 way 4 pin and 3 pin PWM fan power expansion hub, providing a better power solution for motherboard cooling fans inside PC case. 2.Function: Up to 8 fans can be powered by this hub speed controller, and the rotating potentiometer can adjust the speed of 8 PWM fans at the same time. Also comes with a potentiometer extension 30CM. 3.Widely Compatible: Works with 4 pin and 3 pin 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 to avoid damage to the governor. 4.High Performance: High performance all black circuit board is adopted, the hub is small in size, easy to use, and the material is strong and has low resistance, which does not affect the performance of the fan. 5.Strong Sticker Fixation: Use thickened strong sticker to fix, with strong adhesion, it can be easily put into your computer case, and firmly fix the fan hub inside the case. specification:Item Type: PC Fan Controller Product Material: Plastic, Metal Supply Voltage: DC12V Power Supply Interface: 6PIN(2 x 3) Interface Maximum Current: 17A Number Of Fan Seats: 8 PackageList: 2 x Hub Governor and Extension Cord 2 x Chinese and English User Manual NoteThe fan base supports 3PIN and 4PIN fans.
