>>714129481Unless you plan to keep a CPU for well over a decade, it doesn't hurt longevity enough to matter.
Even then, the degradation just means you can't hit your original overclock anymore and you have to drop down to stock.
My Ryzen 1700X still works and it has still been pushed right up to its limit since 2017.
