What does PWM do for fans?
“PWM” stems from electrical engineering and is short for “pulse width modulation”, which is also known as “pulse-duration modulation”. What it means is that you can use it to almost freely control the RPM of a fan. The speed of regular fans can be modified by voltage regulation.
