In the last several days I have noticed my laptop CPU fan blowing constantly. The culprit seems to be 4 identical processes using the same amount of CPU as each other continuously hovering at about 8-12%. This keeps the fan blowing 24/7.
The Task Manager shows the Process name as "Microsoft 365 and Office (32 bit)" and no Office applications are running. When I view the details the executable names are "odt____.tmp.exe" with the underscores representing some 3- 4-character hex value, e.g. C67A.
I can end the tasks but they come back after a time and the CPU fan turns on again.
What are these processes and can I turn them off?
TIA
BTW, I tried to include a screenshot, but the image upload doesn't work.

Thank you for the suggestion, but I don't see that process or task.
I had the same issue but when I killed them they didn't seem to come back.
See if you have a process called CacheTask, it was the only task running and something is starting them. I couldn't test because they didn't come back.
Get-ScheduledTask -TaskName CacheTask
To stop it
Get-ScheduledTask -TaskName CacheTask | Stop-ScheduledTask
I'm seeing the same thing. 2-4 processes, each consuming ~12% CPU. The files are living in C:\Windows\Temp. I can delete those (with seemingly no impact to functionality) but they will return after a reboot.
EDIT: One of these processes returned before a restart.
