I linked the specific wiki page section in an edit to the main post. It’s in the troubleshooting part at the end.
I didn’t try the i8k module but looking at a couple things it looks like the issue was more apparent around Linux kernel 4.15 from a few years ago. I also don’t have any specific complaints with temperature control. The fans only ramp up in the 70-80C range which seems to be quite reasonable.
