1、Computer fan PWM hub-1 divided into10 interfaces, solving the problem that motherboard fan interface is not enough! 2、The 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. 3、High quality materials and smooth operation, direct connection to large 4PIN power supply line. Double-sided tape is available for installation on the back. 4、Firm wire connection and clean casing. Be careful to avoid bending pins and capacitors when installing hubs. 5、Since 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.
