   Dec 12, 2023 · PWM is a technique used to regulate the speed of electronic devices, including case fans, by controlling the width of the electrical pulses supplied to them. By varying the pulse width, PWM can adjust the fan speed dynamically, responding to changes in temperature and system load.

   WHAT DOES PWM MEAN? PWM stands for Pulse Width Modulation. When it comes to most PC fans, they are powered by a constant load of 12v. The voltage never changes, however, by turning the power off and on, we can modulate (adjust) the speed of the fan.

   What is a PWM fan?

   • PWM ( P ulse W idth M odulation) fans allow motherboards to control fan speeds using rapid power pulses (on-off cycles). Simply put, a PWM fan turns off and on very fast to run at lower speeds. This type of fan requires a 4-pin fan connector like the one shown below:

   What is a PWM fan pin diagram?

   • As you can see in the PWM fan pin diagram above, the 4 th pin (blue) allows the motherboard to send a PWM signal to the fan, which controls its speed. Steady pulses of power are used to vary fan speeds in PWM mode, which means that the fan motor switches from the ON to OFF state and back to ON rapidly.

   What is the difference between PWM and DC fans?

   • While PWM fans rely on sending the same voltage (12V) through a fan but turn the power ‘on and off’ rapidly to achieve lower speeds, DC fans can only change speeds by varying the voltage applied to it. This means that a DC fan will run at full speed when a voltage of 12V is applied to it but will slow down when this voltage is only, say, 7V.

   What is a P14 PWM PST a-RGB fan?

   • The fan thus promises extremely efficient cooling, even with increased air resistance, and is therefore suitable for use on heat sinks, radiators and filters. With a wide speed range and the innovative PWM Sharing Technology (PST), the fan speed of the P14 PWM PST A-RGB can be controlled synchronously with all other fans.
