Repasting - do I dare it?

Linus & Alex fun with liquid metal makes sense with desktops it really is just not a good idea on a laptop - Any!

Apples failure here is not really there's, it's Intel's! This CPU chip just runs too hot for the cooling solution Apple offered in this system when you are running heavy process or graphical loads. Repasting the CPU and GPU really won't fix this. You need to focus on the exhausting of the heat making sure the fins are clear of debris as well as the vents are not blocked and pump up the fans more aggressively.

I would not repaste it with liquid metal, as I've read it would eat up the surface of the cpu over time. I would just repaste it with very good normal paste.

The game I'm running, as in the post, is World of Warcraft - a game that requires CPU power. I am running it on fairly low settings, in able to sustain 100 fps. But after like 10 minutes of play time, my CPU throttles to unacceptable levels and stays there. Here is an Intel Power Gadget screenshot of it in action. https://imgur.com/a/h3YN4Ok

I've also tried turning off Turbo Boost, in order for the power/temperature to not spike up as much. I also run fans on max speeds at all times.

Without Turbo Boost, core max is 2,3 - and there are plenty of temperature "space" for it to be 2,3 at all times. But when it goes down to 1,6 etc, it just stays there when I'm in World of Warcraft - no matter the temps. If I exit WoW, it goes back to normal max 2,3.

You might be encountering throttling from current limiting due to the GPU also working hard, or potentially heat spill from the GPU causing the Heatsink to saturate.

There's such small thermal margins on a thin laptop like this that it's likely coming from other components than the CPU that you're not directly getting Temp measurements from.

To me, this seems particularly likely considering you have Turbo off.
