The majority of motherboard manufacturers have stuck with a standard 4-pin 12v connector for RGB LED strips which can usually be found right next to the similar ARGB connector. To keep things simple, when describing the different forms of lighting we'll stick to describing what an LED 'strip' does, if you see an RGB fan the way the lighting works remains the same but they may have proprietary forms of connectivity. You can still do different lighting modes with RGB such as strobing, a gradually fading rainbow between colours, but you can't do some of the more impressive lighting effects that ARGB can do. Although you can change what that colour is, if an RGB LED strip is made up of 50 LEDs, and you want the colour set to purple, then every LED has to be purple at the same time. RGB lighting in a case fan or an LED strip has to be a constant colour. RGB stands for 'Red, 'Green' and 'Blue', each little LED in an RGB strip (alongside practically anything to do with lighting in screens) uses these primary colours as mixing them together can comprise any colour we can conceive. This makes ARGB more controllable and desirable for PC customization. With ARGB, if you want 50 different colours on an LED strip with 50 LEDs, you can do it. TLDR: RGB lighting requires every LED to be the same colour whereas ARGB lighting allows for individual LED control. Its common for lighting choices to get confusing given the way a lot of them are marketed, so what are the differences between the popular options? This article will dive into the differences between 2 of the more common choices, RGB and ARGB. Sometimes it can be hard to decipher what each type of lighting actually does with the huge amounts of lighting options available. It feels like you can't look anywhere in the gaming PC world without spotting some kind of colourful lighting these days.
