Im running windows 11 and have the ryzen 7 7840hs. was running some cpu intensive tasks and noticed that the cpu was thermal throttling even when the agv temp was below the throttling limit. looking further into it, core 6 seemed to be getting much hotter than the rest (about a 6C higher temp average). i looked at the core power draw and frequency and they are all roughly the same across all cores, should i remove the liquid metal and order some phase change thermal pad(s)?
They have a whole thread for that:
TLDR, if you have liquid metal, you can request PTF from Framework for free and you should change LM to PTM as LM is known to cause temperature problems.
You can see Framework’s official announcement here, and the form to apply for PTF is also there. Not sure if they still monitor this form, but you can also request PTM via a support ticket I’m pretty sure.

Contact FW support.
FW was initially designed the FW16 with LM (liquid metal) because in the lab it has excellent performance. However, over time, it has been shown to not stay in position, and thus not cool the cpu evenly.
The solution to this problem is to replace the LM with something called PTM 7950 / 7958.

i got my fw around feb 2025, how do i know if i have PTM or LM?
With these uneven CPU thermals, you probably have liquid metal, but you only really know once you disassemble the laptop (or maybe find a manufacturing date somewhere).
Framework switched to PTM in production around December 2024, but it’s very likely that you got some older laptop from their stock.
This might help
I don’t think the info that they switched to PTM during preorder batches is correct. I got my FW16 in August 2024 when they were already shipping next week, i.e. not a preorder, and there was no talk at all about switch to PTM from Framewok, in fact, they didn’t announce anything until the end of the year. (My serial digits are 421)
But the quoted post has more info than that.
