It’s accurate to lower the AVX settings on your CPU, as it can help reduce temperatures. Many applications don’t fully utilize AVX, so the benefit may be limited. With your i5-9600K running at 5GHz, adjusting AVX could still offer some cooling advantages.

If the app doesn’t rely on AVX, it’s fine. If it does, performance will likely suffer. Your CPU temperature seems normal—no need to be concerned.

It wouldn't be wise to turn off AVX. It's safer to keep it enabled.

Setting an AVX offset in your BIOS causes the CPU to downclock during AVX operations. This reduces performance for those instructions, but if your temperatures remain acceptable, you can keep it unchanged. Tools like cinebench R20 and R23 are suitable for measuring AVX performance during such loads.

AVX adoption keeps rising, particularly after AMD enhanced support starting with Zen 2. The advantage of AVX is that it increases CPU performance, but it also raises heat generation. With careful fixed-frequency overclocking, you can initially adjust for non-AVX tasks before applying the ratio to maintain stability under tougher conditions. Keep in mind that downclocking AVX impacts non-AVX programs simultaneously. On the positive side, since Zen 2 and later, manufacturers opt for power limiting rather than fixed offsets, allowing clocks to reduce adaptively based on the actual workload. If you use an Intel processor with a realistic power cap, it can manage this better; however, most users enable unlimited limits, making offset management more critical.
