Fedora uses the Performance escalator for the CPU but I don't want escalators, just to save power by keeping the lowest CPU frequency at all times across reboots, permanently.

start terminal

sudo -i
cpupower -c all frequency-info

it will show you the current settings, and the current governor in use. My suggestion is to set the min and max frequency, for the active governor, so it survives the restart and you should not have to set them again. to set the frequency, use the following two commands, but use the frequency you want to have it use. I would suggest that you take the lowest frequency, and add 15% to the setting, just to be comfortable with a decent speed setting.

cpupower -c all frequency-set --min 1800Mhz --max 1800Mhz

to verify that it worked, run cpupower -c all frequency-info to see if it shows the adjustment.

Hope this helps.
