The RGB of my CPU cooler turn off before I turn off my PC

I recently bought a gaming PC and wanted the RGB of my computer to be synched, but since I installed signal rgb I got problem with my CPU cooler RGB, when I set the color of it, it turn off before I turn off my pc, to solve this problem I disinstalled signal rgb, thinking it would get his standard rgb, but no, it set himself as a solid color and It would not turn off even when I turn off my pc completely, any way to solve this problem?
