Fan noise since upgrading to Big Sur on iMac Pro

Since Upgrading to Big Sur my fan is running almost all of the time. Even when running only Safari and Mail. This was never an issue before. Is anyone else having this issue? Any suggestions?

Hello


Welcome to Apple Support Communities!

If we understand your post correctly, since upgrading to Big Sur the fan is running almost all of the time. We're happy to help!


Let's try an SMC reset.

You may also want to try an NVRAM reset.

We also recommend starting in safe mode. Sometimes just starting in this mode and then restarting normally can resolve issues like this: How to use safe mode on your Mac


Let us know if you have any questions.
