I'm trying to hit the sweet spot in terms of: T° (heat), performance and noise.
In common benches (Cinebench R23, OCCT...) stock is too hot with a CPU package reaching 97°C, and the NH-D15 fans going full speed. I tried what some other sites and posts suggest (see https://www.overclock.net/threads/asus-maximus-z790-extreme-and-intel-i9-13900k-a-tuning-guide-for-b... and https://www.reddit.com/r/intel/comments/11ttj7d/13900k_nhd15_a_small_guide_on/ ) such as setting:
Others are apparently registering lower temps by using these settings and then gradually lowering AC_LL until the stable point. In my case, I observe zero difference in terms of T° (still reaching 90+°C), and what I find weirder is that the VCore is still as high...
My goal is to have ~80-85°C as max T°, as this is where the NH-D15 silently does its job.
Are there other BIOS settings I should be looking at ?

I have a 13900K and a noctua D15 and use these settings:

Thanks for your reply.
Could you please tell what temp does your CPU reach in heavy benchmarks ?
Because with the settings posted initially, I do see some form of weird throttling in CinebenchR23 single core: The core will go to 5.8 Ghz (good) and then drop to 0 (!?), back to 5.8 etc. Perhaps due to reaching power / thermal limit ?
Also, do you play games that are CPU intensive ? At what resolution (1080p, 1440p, 4K) ?

I am happy to help,
I think there is power throttling when 1 core throttles, i had the same issue before i set pl1 253w and pl2 253w.
I play games at 3440x1440, in heavy benchmarks it hits near 100c but the 13900k can run hot with no problems.
