When you installed Windows 10 did you switch off all the intrusive programs?
These are turned off in the non-express install or whatever they call it.
If you failed to turn these off the processor load may be a lot higher than with your Win 7 installation hence aggravating overheating?
As Simon suggested the processor heatsink paste may need renewing if your heatsink looks clean and your fan is running OK.
The graphics chip might be running too hot. Does it have a fan or is it a silent type?

Fortunately, I have my laptop to continue listening to shortwave while
investigating this issue!
