This is known as pulse width modulation (PWM). The remaining fan headers on the motherboard should be CHA_FAN, PUMP, or M.2. These can be used for various parts, depending on what you have to ...

This is a dead-simple PWM fan controller that simply lowers the speed of the ... The output signal from the logic level shifter is sent through the 1N4001 power blocking diode to the fan header. The ...

Of course, the standard way of controlling CPU fans these days is with PWM, so he built a circuit which essentially converts the PWM signal from the motherboard into a phantom thermistor.

Then you can stick the connector on the GPIO header, connecting the YELLOW cable to PIN 4, BLACK on 6 and BLUE on pin 8: doing so, you will have to use GPIO 14 to control the speed of your fan. I ...

This hub provides four USB 2.0 headers, supporting up to eight downstream ports with a total output of 2.5 A, and includes six 4-pin PWM connectors, each capable of handling up to 2 A for UNI FAN ...
