Hello i wanted to make sure if my
MX-4 will be enough for this cpu, will be using
*Dark Rock 4 Air Cooler

My goal is to get 4.7GHz full load 65-70c if thats possible?

So i was thinking and reading about Thermal Grizzly Kryonaut . Will this be better then mx-4?


Thanks.

Typically, even between "high-end" and "mid-range" stuff, there's only a 1-2'C swing either way.

Your limiting factor is going to be Intel's TIM between the die & IHS regardless.

As for temps, 4.7GHz across all cores, will depend on the workload specifically.

65-70'C under "normal" mid-range type loads, might be doable. Under workloads that mimic stress-tests (ie 100% usage, AVX instruction set etc), not a chance. High 80's to low 90's I would expect (at least without running the cooler at 100%).
