Keeping this in consideration, how does a fan speed controller work?
In a capacitive type fan regulator, various combinations of capacitors is used to control the speed of the fan. (or voltage across capacitor is inversely proportional to the capacitance). Hence, if capacitance is increased then the voltage across the capacitor decreases allowing more voltage across the fan motor.
is fan controller necessary? Fan controllers aren't necessary, more of a personal preference to slow down fans which are loud at full speed. I've never heard of fan controllers making them louder unless it's a weird situation where pwm fans are clicking at lower speeds.
People also ask, what do fan controllers do?
Having a PC fan controller in your system makes it much easier to monitor temperatures. Most feature software and allow you to manually adjust fan speeds and make your system the perfect balance of cool and quiet.
How a capacitor works in a fan?
The fan has an AC single phase motor. Now when capacitor is added to the additional auxiliary winding of stator it creates field which leads by 90 degree to main winding field so we get two field which are 90 degrees to each other, resulting a rotating field responsible for start of the fan motor.
