I5 8600k processor cooling

Solution
You have the wherewithal to try it and see how you do.
If you find the cooler to be insufficient, as I think you will if overclocking, then look for something better.
If you will be overclocking, I would look for a cooler with more capability.
A good starting point is the noctua TDP guide.

NH-U14s or NH-H15s are the recommendations,
