Features: ARGB PWM 2 in 1 fan Hubs: Each port of the ARGB PWM fan Hubs PWM function, which can adjust fan speed synchronization and easily expand computer case fan to cooling capacity. Supports 5V 3pin ARGB PC fan and ARGB light strips. the lighting effects of 5V 3Pin interfaces devices. Magnetic fixed back computer fan Hubs: 1 to 8 fan hubs adopt magnetic fixed, which to the surfaces of the PC shell without double-sided tape, making it very convenient to place anywhere in the computer case. PSUs SATAs power input PWM fan Hubs: The fan is directly input into the computer power SATAs interfaces power supply, which can work with 8 fan. The fan Hubs prevents strays current and no voltages loss, ensuring smooth and efficient fan speed. 5.24inches (approx. 14.9cm) long ARGB fan Hubs: The size of the PWM fan Hubs is 5.24x1.89x0.56 inches, and its small and shape makes the wiring inside computer case neat. Widely compatible ARGB PWM fan Hubs: The fan Hubs distributor supports up to 8 fan, including 8 4pin PWM port and 8 ARGB port for ARGB fan and ARGB LED strips. Installation is very convenient. The 4pin PWM port supports both 3pin and 4pin fan, but the PWM function depends on the computer fan, so the 3pin fan connection Hubs not have PWM function. Specifications: Materials: Plastic Styles: Regular, Remote Controls(optional) Package Includes: 1PC ARGB PWM Fan Hubs note: Please allow 0.5-1cm error due to manual measurement. please make sure you not mind before you bid.
