The Introduction of PWM - Antec April 15, 2022
PWM is the acronym for Pulse Width Modulation. It is a way to control analog devices with a digital output. Another way to put it is that you can output a modulating signal from a digital device such as an MCU to drive an analog device. It’s one of the primary means by which MCUs drive analog devices like variable-speed motors, dimmable lights, actuators, and speakers. PWM is not true analog output, however. PWM “fakes” an analog-like result by applying power in pulses, or short bursts of regulated voltage.

Now I believe you know how PWM works now. If you are interested in the fan with the PWM function, you can check our latest case fan, the Prizm X 120 ARGB.
Prizm X 120 ARGB 3+C
- Dual-Ring Design
- 24 Independent RGB LED Beads
- Motherboard Addressable RGB LED Lighting
- Fan controller (included)
- PWM Intelligent Case Fan
- Hydraulic Bearing
The Prizm X 120 ARGB case fan features a dual-ring aperture design, which allows you to display ARGB effects on both sides of the assembly.
