I doubt it's a design issue because we would have had more than just your report of the issue.


Download and run Etrecheck. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support  to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.


IMPORTANT:

Before running Etrecheck assign Full Disk Access to Etrecheck in the Etrecheck's Privacy preference pane so that it can get additional information from the Console and log files for the report:


Also click and read the About info to further permit full disk access.



Copy the report



and use the Additional Text button to include the report in your reply.



Then we can examine the report and see if we can determine what might be causing the problem.

The best antivirus, cleaning app, and overall maintenance app for Mac OS is Mac OS itself. All you need to do with Mac OS to keep it secure and running well is to keep it up-to-date and do periodic (about 1x per week) restarts. Other than that, leave it alone. Adding third party antivirus, cleaning, security and other types of maintenance apps to Mac OS adds no additional level of security. The only thing these apps do is have the opposite affect users want. They make Mac OS slow, unstable, generate odd behavior (much like you are experiencing) and make Mac OS appear buggy. 

 

Please locate the developers uninstall instructions for CleanMyMac and follow to the letter. Then restart in Safe Mode per the directions in Use safe mode to isolate issues with your Mac and then restart normally.

This appears to be an issue Apple doesn't want to deal with. I've had fans running at 3800+ at random times when not under load and cool room temperatures. Apple Diagnostics gives codes PPF004 and PPF003. I took the iMac into the Apple Store "Genius Bar" and after a week had me pick up the computer stating they could not reproduce the fan issue. That's it. Come get your computer, there isn't a problem. Everything's fine for a few days and now the fan is starting to act up again. Apple used to be a reliable company. Now it seems everything is politics and CYA.
