Expand Fan Interfaces: 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 the PWM cooling fan hub, the governor can provide power for up to 8 fans, and the rotating potentiometer can adjust the speed of 8 PWM fans at the same time. Application: 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 powerful full black board is adopted, the hub is small in size and convenient to use, the material is .

Can be used with a motherboard to limit the fan's maximum PWM duty cycle/maximum speed; within the limit range, the motherboard can still freely adjust the fan speed. Even with an external motherboard PWM signal, the fan speed can still be freely adjusted within this limit range to achieve speed limiting.

PWM frequency: 25KHZ (± 1KHZ). PWM signal amplitude: 5V (no-load). Support low-temperature shutdown of fans within 3A, and support reverse timing fans. Circuit self consumption: less than 40mA (test value at 12V, for reference only).
eBay
The PWM frequency is 25KHZ, which can adapt to most 12V adjustable speed fans on the market. Short-circuit the PF pad to reverse the duty cycle. The duty cycle can be adjusted from 0% to 97%, with a wide speed range.
