Fan runs constantly on 2021 Macbook Pro M1

After not hearing the fan at all since I bought the device, the fan started running at top speed today. No new software loaded, no visits to questionable web sites, no new hardware, no video editing involved.


Reboot didn't work. Turning off for a few minutes, then back on, didn't work.


Any ideas? Thanks.

MacBook Pro 13″, macOS 12.1

I have this same issue except on my iMac Pro. The problem seems to have started at some point after updating OS Monterey 12.2. I have also tried rebooting, holding the power button for 10 seconds and then turning on, as well as shutting down the Mac, unplugging power cord for at least 15 seconds and then powering it up again - still the problem persist. I have also started up in safe mode.


Anyone else have similar issue? Is it an issue with the OS update to Monterey 12.2?


thanks much
