This is driving me nuts! The default setting for the TT Riing Trio 12 rgb fans is so bright. I setup all the fans, downloaded the software and it worked! First try flawlessly. I set the fans to what i wanted ( was super impressed by the way) and I turned down their brightness. Then I turned off my computer and went to bed. The very next morning I turned it on to find them in their default stage again. I said fine and went to turn them back to how i had them but now, TT RGB PLUS won’t open D
