The following screenshots are of MacFanControl my 2018 Mac mini.

The 2018 has been on all day playing Music in the background.

I have come and gone numerous times during the day to use Safari and Photos.

Not to mention that it runs dual displays, a 2.1 speaker system and several external drives.
