You will get much more benefit from the better Graphics Card than the jump from 6 to 8 cores. Yes, basically Planet Coaster can utilize 8 cores/16 threads and even more, but in large parks, you are bound by just a few threads, mainly the "drawcall thread" which is bound to one single core due to the DirectX 11 API used in Planet Coaster.
The 6-core/12-thread CPUs are very capable for any game, even Planet Coaster and you will also outperform my first gen 1700X 8-core ryzen with the newer versions.
Also nothing will break the CPU. The Boxed coolers from AMD are working quite well, not as good as a high end air cooler or even my custom water cooling loop but they are really good for what they are- Boxed Coolers. ;-)
It doesn't matter how long you are playing without any break, the AMD CPUs are as reliable as Intels. The times where the platforms where flawed and instabilities have happened even on out-of-the-box settings are long gone. Not many people are aware of this, but it wasn't that much of AMD's fault but more of the chipset manufacturers. Back in the day, there where mainboard chipsets from VIA or NVidia which worked not that well sometimes. But on todays standards, the CPU manufactures also delivers the chipsets and since memory controller and (if integrated) graphics solutions went from the mainboards so called "north bridge" directly into the CPUs those issues are basically gone.
All thats left on modern platforms is a sort of "south brigde" which is more like a platform controller hub for IO like SATA, additional PCIe lanes, USB connectivity and so on.
So don't worry, if you dont do unstable overclocking without knowing what you are doing, AMD's platforms and CPUs are as reliable as every other manufacturers products.
