I’ve had this fan running at high speed for … years using 18.04 lts. It is not 6280 db, but it is annoying and probably not great for my fan. Did screw up the fan settings?
I recently thought that using a new fresh Ubuntu version would fix the issue. I backed up all my data and reinstalled Cinnamon wiping all. 
I think at one time I played in the terminal and might have screwed up entering the numbers or I did not put a space or did not take out one of the numbers: 62 and 80. I remember it took me weeks to find a solution and that solution made it worse.
Is there an easy solution? No, use ear plugs for life! 
I would be so grateful if someone had a solution.
PS: I know very little about the terminal commands, but I can copy and paste well.
