I downloaded coconutBattery to get some info, but not sure what to make of it:

Any ideas what might be the problem? Thanks.

I am adding this screenshot of Activity Monitor, which shows that kernel_task is running at over 700% CPU capacity, whatever that means.

EDIT 2:
Here are two screenshots of the app “TG Pro." Everything looks green except for the fans, which probably just adds to the mystery…
