Well, I can't say how much you'd have to oc your CPU, but I can for sure tell you that it won't be easy to even get it remotely close to not bottleneck it.
You'd have to get a pretty high end air cooler or 240mm AIO watercooler, but then again. Would you really spend that much money on a low end CPU? If you really want to go out and buy a beefier cooler, something like a Noctua nh-d15 or Corsair h100i would be a bet.
