Yes please !
Maybe there is a config file somewhere but I haven't found it.
The RGB color temperature indicator mode would actually be useful (and pretty) if it could be configured so one could select what temperatures shall match specific colors. As it is now, on my 1080 TI STRIX, cooling is so efficient, the color is always green, even under full load. I want to have it blue when idling, green up to 58C and red at 65C for example. Make this configurable in a simple little table.
Another idea would be to add modes to correlate the colors to fan speed or power consumption. That way, we can keep GPU constantly cool (like we should) and still get some indication of activity.
