I reviewed the 13900k assessment from TechSpot (https://www.techspot.com/review/2552-int...i9-13900k/) and noted they tested several top-tier AIOs, including premium 420mm models. They mentioned attempting the Arctic Liquid Freezer II 420mm as well, hoping it would improve performance, but found it didn’t make a noticeable difference.
I’d begin with a manual under-voltage, open the XTU and apply prime 95 or switch to r23. You can gradually lower the voltage while keeping stock clocks at 1.25V as observed. Setting a P1 power target around 180W should work well for gaming. For more demanding tasks, it may slightly reduce clock speeds to maintain stable temperatures.
