Until you accumulate a fair amount of general Zen3 knowledge I'd recommend staying away from CTR. It's not a tutorial program for overclocking, and what CTR attempts to do is provide you with a manual, multi-core overclock over the base ~3.8GHz clockspeed of the CPU while at the same time allowing you to do so on less voltage than the CPU consistently modulates while under load. It works OK at doing that...but I'd wade into things before trying to use this. Most people are very happy with their CPU's stock performance for gaming or other load conditions, as you have said. This program is basically for those who like to tinker--one thing about the manual overclocking mode you need to be aware of--when you manually overclock--even by 1MHz--you automatically lose your single-threaded boost capability--that can help performance in some games that don't do multithreading very well or very much or both (which really is the case for the majority of games on the market today.) Max safe operating temp for your CPU is 90/95C, according to AMD. The CPU is designed to run 24/7/365 at those temps or lower without a problem. Running under load at 80C or 85C or even 90C is absolutely nothing to worry about--but people want to worry about many things, it seems, anyway... (My Zen 2 3900X, air-cooled with the stock AMD-supplied cooler has never seen 90C, much less 95C, and typically runs under load at temps no higher than 65C-80C, depending on the software being run.) Your 5900X automatically clocks its cores, on a core-by-core basis, according to the loads you ask it to bear. IE, when running light tasks your single-threaded boost comes into play and the CPU runs differently under light loads--runs cooler and with less voltage. It already does that--automatically. CTR not required. Your Zen 3 CPU is even more advanced at auto-overclocking than my Zen 2 3900X is--and my Zen 2 does a great job. It's only because of the way that Zen2/Zen3 CPUs are designed--to auto-overclock and auto-regulate voltage per-core in response to demand (anything over base clock being an overclock) that a program like CTR can be written in the first place. Old style monolithic designs can't do these things and a CTR program wouldn't work on the current Intel CPU architectures, for instance, for that reason, AFAIK. Basically, CTR allows you to take the current capabilities and operating characteristics of your 5900X and organize them and refine them in certain ways so as to provide you with the result you prefer, or think you might prefer, etc. One size does not fit all, etc.
