Glen, I'm not sure how much this will help, but my old Acer laptop running Jessie seems to be fine out of the box.

A quick search will give you some clues: https://duckduckgo.com/?q=site%3Adebian.org+fan+control&t=debian Also some packages may help, check out fancontrol and thinkfan. There are others. Keep us posted. And please reply below this post so discussion flows logically. Good luck!
