It has never been overclocked or stressed in anyway, the most intensive usage it has seen is from games like World of Warcraft and Diablo 2 Resurrected. The cooler used on this chip was a Noctua NH-D15 which is more than enough. This is an OEM tray CPU which means it did not, and will not, come with a stock cooler or retail packaging.
This means you will need to invest in your own CPU cooler if you do not already have one.
