GELID debuted the Radiant and Radiant D series case fans at the 2018 Computex, in their 120 mm avatars. These fans are characterized by an innovative new impeller design with sawtooth edges along the business end of the blades, which act as chevrons, and work to minimize noise from the whiplash of the blades; and RGB LED illumination using 9 diodes. What sets the Radiant apart from the Radiant D is the latter's programmable lighting. There are sub-variants of both that include a black frame, or translucent, frost-white plastic. Both feature double ball-bearing hubs. The two also take 4-pin PWM input. The company didn't put out specifications such as speeds, air-flow, or noise outputs, yet.
