Fan Curves?

[ifsr]

I just swapped out my i5 8400 for a 7700x, i slapped a ThermalRight some something assassin 120 on it. I was wondering if i should tweak the fans in bios, I haven't really messed with it before since cpu cooler wasnt a issue. I know this cpu will run a bit hotter.

You always should adjust your fancurves, but mostly to mitigate the noise, and then to get ahead of a temp spike. But usually handling the temp is done a lot better through adjusting your core voltage. What I usually do is adjust the fan curve so the noise under 60-70c is as little as possible and also in a way that I can't really hear it when the PC is on idle and light scenarios.

 

Don't secessarily adjust it based on Cinebench temps, but do it based on what  it sounds like when you're browsing or playing games on avrage. But that's how I personally do it, I value acustics a lot more than temps when it comes to fancurves.

Awesome, mine kicks up to 70 but then cools down in seconds back to 40-50, it's not even loud tbh so im going to up it a bit more.

I would say don't, if you're just a 70c max. You'd just be adding noise to your environment in return for nothing substantial. There isn't any difference between temps under 70c. Unless what you're doing is overclocking, then it would be a different discussion. I would only make the fans more aggressive if I'm getting hot temps all the times, hotter than 80c. Only time you should be worried generally is when your processor is sticking to 80c and above in most situations and games. But even then it means something else is not right in there, like the cooler being not a good match for the CPU, or a lack of airflow, themal paste shenanigans and such issues.

yeah, me too, which ironically means being super aggressive... 70c is what i consider absolutely max too to be tolerable.

yep, as long the chip is capable always uv first thing.

you're probably fine
