If you're using it to overclock your CPU then Ryzen Master is a much better option. Everything that it can do for you can be done in bios with much more control and infinitely better results. Dragon Center is a notoriously terrible app and unless you specifically need it for something then I really wouldn't advise using it at all. In my case on x570 it's the only way to access Mystic Light for RGB control. In his case he didn't really need Dragon Center and decided to just uninstall it. You can increase the time until each fan system changes state to seconds (3 or 5 I think) and if you do this on the down turn for each fan it will stay at a higher RPM for that amount of time before even considering going slower.

At stock it's set to do this very rapidly (maybe 0.1 seconds) so especially with Ryzen and especially in idle your fans will be going up and down constantly. What I do and what also worked for him is to add time into how long it will take the fans to adjust down. My advice to him that he said worked was to just control your fans through Hardware Monitor in the bios. I just ran into someone with this very issue the other day.
