Gelid Radiant-D 120mm Extreme Performance Programmable Digital-RGB PWM Fan GEL-RADIANTD-20

Brewed with top technologies and passion; the Radiant-D RGB LED Fan is a special craft for modders and gaming enthusiasts. It adds programmable Digital-RGB control with individually addressable LEDs that enables variable colour settings for each of the 9 LEDs installed to the fan and fosters a stunningly vivid RGB LED lighting experience. Along with the extreme performance profile and bold design; all that makes the Radiant-D a perfect ingredient for gaming rigs and custom PCs. Just try it; ignite full colours of life inside your PC!

9 Full Colour RGB LEDs - circularly mounted high-bright LEDs for a stunningly vivid RGB Lighting experience. Programmable Digital-RGB Control - limitless colour modes and lighting effects via individually addressable RGB LEDs. Extreme Static Pressure - powerful impeller with the unprecedented static pressure and performance profile. High Precision Shark-Tooth Blade - 3D optimized blade for even higher airflow and lesser noise. Noiseless Motor Drive IC - newly designed and enhanced motor driver to eliminate clicking noise. Ultra-Durable Double Ball Bearing - carefully selected top-quality ball bearings for ultra-durable operation. Wide Range RPM - extended fan speed in the range 500 – 2000 RPM. Broad Compatibility - all modern motherboards with RGB Lighting controls and 5V Addressable headers are supported.
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.

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.
