Fan loud with Safari use

My iMac's fan is running like crazy lately (maybe last week or so). I'm on macOS 11.4, 2019, 27-inch. It seems like it might be Safari-related, so I quit Safari and a few other apps (like Word, Excel, Notes, and Teams) and the fan has now stopped. I'm not doing anything even remotely intensive on any of these apps, and my iMac feels cool to the touch (front and back) regardless if the fan is running or not. Any ideas about what has changed? Any reports of issues like this with 11.4?

I got on chat with apple. The fan has only been doing this since I updated to 11.4. She had me reset the SMC by shutting down the computer, unplugging it for 15 seconds, plugging it back, wait 5 seconds and turn it back on. I think that may have fixed it. If not, I'll run through these steps you outlined and report back. Thanks Luis!
