My 2.4 voron’s motors and drivers are pretty quiet. The electronics bay fans I initially built it with not so much. Those fans are now noctuas, which move more than enough air for this type of application and are very quiet. I recently added bed fans (well, really an under bed filter) and they’re a little louder but still not that bad. I work from home 3-4 days a week with the printer about 12 feet behind me. I spend most of my days on meetings and no one has ever mentioned printer noise, but someone will occasionally comment on the print head moving around.

I’ve never owned a Prusa, but my old i3 clone was way louder.
