PC Chassis Fan Hub Computer Tempreture Regulator 4Pin CPU Cooling Hub Fan Chassis Fan Fan Speed Controller Case Fan for Computer Cases with PWM Cable(SATA)

Address the lack of motherboard interfaces: PC Chassis Fan Hub solves the problem of the lack of motherboard interfaces and focuses on dealing with fan cables.
Two-color interface: The PWM interface is connected to the CPU fan interface of the motherboard and the red interface is a dedicated interface for the CPU fan (with speed measurement function). The black interface is a conventional PWM fan interface (no speed measurement signal). Proper power supply and temperature control: The power supply can be powered directly from the power supply to reduce the load pressure on the motherboard. The PWM of the temperature control line is connected separately to the motherboard so that the power supply and temperature control are correct. Suitable for 12V motherboard 3Pin/4Pin fans: The Computer Tempreture Regulator is suitable for 12V motherboard 3Pin/4Pin fans. (A 3-pole fan can also be used. However since the 3-pole fan has no PWM speed control it runs at full speed when connected.
)Even speed adjustment: Expand the four-pin connector of a single motherboard to multiple connectors for even speed adjustment. (If your fan is a 3-pin fan you can also plug it in but it won't reach the PWM control speed. )
