Dispatch to this address when you check out . -PWM Fan HubComputer fan PWM hub-1 divided into10 interfaces, solving the problem that motherboard fan interface is not enough . -InterfaceThe PWM interface is connected to the motherboard CPU fan interface, and the red interface is dedicated to CPU fan. The black interface is PWM conventional fan interface. . -Durable MaterialsHigh quality materials and smooth operation, direct connection to large 4PIN power supply line. . -Simple installationFirm wire connection and clean casing. Be careful to avoid bending pins and capacitors when installing hubs.Double-sided tape is available for installation on the back. . -TipSince the main board/fan controller board can only receive one speed signal, the other nine traditional fan interfaces have PWM function but no speed signal.
