The Zen of Python has answers for this conundrum.

With the Wraith Prism heatsink fan included with many modern AMD Ryzen processors there is configurable RGB lighting, which unfortunately AMD hadn't publicly documented or offered a Linux utility for manipulating the RGBs under Linux. Fortunately, there is now a straight-forward solution for dealing with those Wraith Prism RGB LEDs thanks to the open-source and independent CM-RGB project...
