Entered BIOS and looked for acoustic/power/performance settings which led me to some way to reduce fan intensity in BIOS.

What I installed and did that helped:

sudo apt install cpufrequtils
sudo cpufreq-set -g powersave

I could’ve used fancontrol + pwmconfig if my server supported it.

I decided to unplug all fans but the CPU fan and just use cpufreq-set to powersave. Check current mode with cpufreq-info to make sure it’s set to powersave.

I think it’s already consistent across boots from the command I tried?

I checked temps with sensors.
