[Expand Fan Interfaces] - Excellent 1 to 8 splitter 8 way 4-pin and 3-pin PWM fan power supply extension hub, it provide a better power supply solution for PC computer case internal motherboard cooling fans. [Function] - Through this hub, the governor can supply power to up to , and the rotating potentiometer can adjust the speed of 8 PWM fans at the same time. [Widely Compatible] - For both 4-Pin and 3-Pin fans. If the fan does not support PWM speed regulation function, the speed regulation function is invalid. The total current connected to the fan shall not exceed the maximum current value of 17A to avoid damage to the governor. [High Performance] - The high-performance fully black circuit board is adopted, the hub is small in size and convenient to use, the material is strong and the resistance is small, which does not affect the fan performance. [Glue Fixation] - The thickened glue is used to fix it, which has strong adhesion, easily fits inside your pc case and can firmly fix the fan hub inside the chassis. colour: black Material: Metal+Plastic Size: 4.2x2.9cm Package Contents: 1 x fan hub Only the above package content, other products are not included.
