Fan coming on frequently and rather loudly

I have an iMac with Intel i9 chip & running OS Monterey 12.6, so fairly new. Not doing anything particularly industrious with it and its not in use for hours on end. Just lately have noticed the fan coming on almost as soon as the computer is powered on. It seems to be staying on too. Will shut off if an application is closed, but so long as something is in use, the fan is on. Any suggestions as to why all of a sudden this is occurring?

1 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.


2 - Does the issue present in this mode ?


3 - Sometimes a Safe Boot followed by a Normal Boot will just put things right.


4 - If not - there could be something in the main User Account playing up. To further isolate this - Set up users, guests, and groups on Mac. Then log out of the Main User account and log into the dummy account and test again if the issue persists.


5 - If the issue is present in the dummy account - then, this appears to be a System Wide issue on the computer.


6 - Download the Application Etrecheck directly from the Developer.


The application is free or paid from added features. 


It will take a Snap Shot -  both the hardware and software.
