Currently I cannot find any guides or examples of undervolting (outside of XTU) for the XPS 15 9560 (kaby lake 7700) from within Linux / Ubuntu.
Using TLP or other programs, is it possible to undervolt the CPU to reduce temperature / fan usage?

So your question is about methods to use to lower the voltage going to the CPU that what it's rated for, etc.? – Vomit IT - Chunky Mess Style Sep 04 '17 at 14:02

Correct, artificially through software / bios lower the voltage going to the CPU in order to reduce fan and temperature. Commonly known as undervolting – Ray C Sep 04 '17 at 15:51

Have you figured this out? I'm also trying. – Oscar Smith Nov 27 '17 at 18:34

I've found this project through arch pacman. It's also on Github and apparently allows the setting of the max temperature, max TDP and changing of the voltage. I have not yet checked the code yet and because it's fairly new and no comments around it I wouldn't install it on my production machine without checking the code first.
The whole thing is based on this

Interesting I'll have to give that a shot. Even though my OS is expendable on my spare XPS, it may damage hardware from what I can tell so would need someone with more expert knowledge to test – Ray C Jul 06 '18 at 23:11

Afaik, undervolting can't damage your hardware. Otherwise running out of battery would do the same. – pascalwhoop Jul 08 '18 at 00:42
