Big Sur and Fans on iMac iMac (Retina 5K, 27-inch, 2019)

Anyone else noticed the fans kick in really early on Big Sur? My 3.6 GHz 8-Core Intel Core i9 turns them on and off with just mail and a browser turned on. Never ever heard them on previous version.

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?

Fan Running on iMac I have a 1 year old iMac running Big Sur 11.3. The last couple of days the fan is coming on from time to time. It's never come on before and I'm not doing anything different on the computer than I ever have. The fan issue seems to correlate with the most recent OS update. I've turned off and unplugged the iMac and then restarted and no change. Any suggestions?
