What voltage would you recommend and what All Core Clock for the cpu?
I have no plans for water cooling as I bought the Noctua for £100 and I'm just not wanting liquid cooling.
Go lower from what it's currently running, not all CPUs are the same. It would probably do 1.2V at 4.8GHz but not all CPUs are equal
Also turn up the loadline calibration to the middle setting (whatever actually is at the middle, since there are different ways to call them) if you use manual mode. Keep it to.auto if you use other modes like adaptive
