Lamptron, the specialist in PC fan controllers, rolled out the CL420, a combination of a fan-controller, and an RGB LED lighting controller. The unit fits into a 5.25-inch drive bay, and gives you four domains, with two selectors, each - fan-speed, and color spectrum. In the fan-speed mode, you can adjust speed of up to four 4-pin PWM fans per domain. In the color mode, you turn the same knob to adjust color from across the 16.7 million-color RGB spectrum. It's not just fans, you can also directly plug in your RGB LED strips. The company didn't mention pricing, but announced that the CL420 will go on sale some time this August.
