I use a RGBW stip with my Farbwerk. That is a strip that not only has the RGB, but also a 4th set of LEDs that are white.
I use one channel of the Farbwerk to control the RGB, and a second channel to control the White LEDs.
I have it programmed so that the white LEDs are on during normal operation, but if the system (I monitor CPU temperature) begins to heat above a predetermined setting, the white LEDs switch off and the RGB LEDs come on. First Blue, then green as the temperatures increase, and finally red when I approach the maximum temperature setting.

Thanks, Could you please tell me which brand is that RGBW strip you are using?
