STANDARD RGB AND INDIVIDUALLY ADDRESSABLE RGB EXPLAINED

In standard RGB applications, this type of fans uses the standard RGB LED header with 4-wiring: 12V, R, G, B. All the LEDs integrated with the fan are then connected onto the same 4 busses, they are all controlled as a whole, so they each will output exactly the same colour.

It’s like you set colour for an object in your graphics editor, for example, Red: 25, Green: 50 and Blue: 125, an external RGB controller or motherboard drives the standard RGB LED fan in the same way by altering power on the colour busses at a proper duty cycle – the Red, Green and Blue bus, respectively – to output the desired RGB colour.

Of course, colours can be managed dynamically, with numerous lighting effects in series. But uniformity of the LEDs – one colour for all the LEDs at a time – limits RGB lighting effects to some degree.

RGB Fan Headers

Radiant-D Individually Addressable RGB

Unlike the standard RGB fans, controls of the individually addressable RGB fans are digital in nature. For this case, the fans use the addressable RGB LED header with 3-wiring: 5V, D, Ground. And the LEDs integrated with the fan have a special companion IC which drives each of them individually: it resides on a one-wire serial bus and sends commands like “LEDs number 3, 5 and 6: switch to green” to set the desired colour per individual LED. So, each of the LEDs has its own ID and is controlled independently from the others. In turn, an external app can be used to program the IC giving virtually unlimited options of colour modes and effects. Rainbow-circle, rotating colours, multipoint pulsating colours and some other stunningly vivid RGB lighting effects are available only with the individually addressable RGB fans. But, as far as this type of fans supports digital RGB controls only, it’s up to your motherboard to provide a full-featured RGB app to discover the excellence of RGB lighting.

Please refer to your motherboard manual before connecting the individually addressable RGB fans.
