Pwm Fan Wiring Diagram. In this situation your potentiometer is acting as a resistor between the 12V PWM. Question Converting Laptop Camera to USB.
The second fan will not be PWM controlled. It will be ONOFF only. A resistor to either the 12v or PWM wire on a 4-pin CPU fan to retain the automatic.
3 pin and 4 pin Fan Wire Diagrams.
Automated Logic ZN341v Automated Logic. PWM Pulse Width Modulation or modulation with the width of an impulse is a widespread term in the world of electrical engineering. These are PWM fans which means they need a continuous sequence of pulses timed accordingly to how fast they should be spinning. It has a broad range of application like in the field of telecommunications.
