while the 5600x is generally built to run up to 95C... i personally don't like seeing it at or above 80C.
The stock cooler definitely isn't sufficient for doing this as often even in a decently cooled system, will run in the realms of 90C give or take, and that's without PBO doing anything, anything above 80C and it'll throttle itself already too.
A wraith prism or wraith max AMD cool however will drop those peak temps by 20C easily. In fact i've built enough 5600x's with wraith prisms and compared to their original stealth's, that running maximum 67-73C with those heatsinks is guaranteed under absolute maximum loads (again properly cooled case, and running an ambient temp of 24C).
So it's interesting to know a H60 CPU is equivalent to a Wraith Prism/MAX heatsink.
