i7 8700k OC temperature

It'll depend greatly on the chip - some need less than 1.3V to be stable at 5GHz while overs need over 1.4V, and voltage pretty much dictates what temps will look like.

That said, that cooler is decent but on benches it's usually a bit hotter than a Noctua NH-D14. Would a Dark Rock 3 at 1.3V perform better than a Noctua NH-D14 at 1.4V? Very possible. That's kinda why this will all boil down to your specific chip.

If you haven't bought it yet, you might wanna just grab an NH-D14 because it's probably the best air cooler out there, and it's always better to have the best cooler possible and just reduce any chance of not having thermal overhead.
