Oh ok will check that then 
thanks!
I’m preparing to replace LM and do PTM sandwich. the easiest way to check that LM does not work is to install hardware monitor and cinebench R23. when I run Cinebench multicore test, I can eailsy check that I cannot excceed APU STAPM > 25W which is very low and it is caused by thermal limit hitting 100C

Jep definitly you are affected. And when you have it open, you should also consider the ptm sandwich.

I was wondering whether there is a way to scientifically test the efficiency of the heat sink.
If we had a temp sensor on the heat pipe, we could measure the relative temps at the CPU and the heat pipe and the rates of rise etc. and get to some measure of efficiency.
We don’t have that, so I was thinking maybe we could do it the opposite way.
Heat up the CPU (with stress-ng or similar), and leave it there for a few minutes so it reaches a steady state. Then turn off stress-ng and see how long it takes to cool down again.
I think we could do that without needing a temp sensor on the heat sink.
I am not a heat/cooling expert, so I was just wondering whether it is worth a try.
Maybe create a script that loads up the CPU and the unloads it and measure the temps through the whole process. Then look at the graphs of the temps and see if one can see differences between good heat sink vs bad heat sink ?
Maybe even tell if the problem is the PTM on the CPU, or the solder on the heat sink itself ?
Ummmm for those people how don’t happen to know what the ‘PTM sandwich’ is. ( you know who you are…. 
) what is it ?
[edited to delete my incredibly bad guess…LOL]
you need to remove one part of the heatsink and replace it with
PTM
copper shim
PTM
here is post related to removing that extra part which should be replaced by PTM copper shim Uneven CPU thermals! - #156 by Alex_Uta

Riiight… Errrrr….. ok that seems to be a little more extreme than I was thinking I would do..
Also seems I have to get the PTM from elsewhere as framework seems to be all out.
and for a hot country like Australia is.. it seems very hard to find any of the Thermal conductive or insulative products that I want.. you would think things to make thing cool better or prevent heating up should be all over the place!!! oh well..
thanks guys for all this info.. seems I’m like 2 years late in discovering it was affecting my laptops.
The sandwich is optional, simply replacing the liquid metal with the PTM pad should get you back to expected performance. The copper shim sandwich mod is for achieving better-than-expected performance. It’s also not the complicated tbh. You just remove the aluminum shim with some plyers and replace it with a 0.8mm copper shim (available on Amazon) using another PTM sheet to hold it in place.
Ideally, you also polish the copper to a mirror like super flat surface, but I suspect that even without this step it’s still an improvement from the aluminum shim.

ModDIY and LTTstore.com sell genuine PTM7950 and LTT ships internationally. Idk if ModDIY does

And also the Thermal Grizzly Phase Sheet is Genuine PTM and should be available nearly Worldwide.

Sooo seems framework had a couple of pads left and even with the shipping cost came up as cheapest option for me
sooo in a few days time the adventure begins! Lol

I had a tough time removing the solder remains of the aluminum shim and in the end the vapor chamber surface was bent inwards a bit so I couldnt reach the last bit of the aluminum shim solder with my sanding stone…
But it seems like that wasnt a problem at all
I bought both the PTM and copper shim from ModDIY

A little unrelated, but thought this was the best place for it.
After using ectool to up the power output from my power brick for a while, it seems like the PSU can overheat and turn off for a moment if I lay it on the wide-side. So, I went and got some heatsinks for the outside and after a 2hr burn-in test it doesn’t seem to overheat anymore. If that changes, I’ll try to update my post.
Before anyone asks, this is what I used: Amazon.com

Hey all, Just wanted to say that I have just completed my LM replacement with PTM7950.
it was not among the top 10 fun activities that I have done, when did everything get so Small… about the only connector that was comfortable to reconnect (disconnection is always easy) was the speaker cable.. and the hardest was the fingerprint reader..
prying off the heat sink was interesting they did not want to come apart easy, but thanks to the others in this thread having walked the steps before me it was to so bad. Thank you to the first person to do it that must have been nervracking.
but the guide that FW has is good.. the comments people have done help…
so all up worth doing for sure.. my laptop is now sitting at the coolest it has ever been with LM it was sitting at 60c but with this new pad its in the 40s. and so much quieter.
ok I guess I should go re-run the bench marks and see what I get..
but thanks again everyone for all the info, made the walk so much easier.
Well… with the new PTM inplace things look better…
also seems that the r23 benchmark is +2000 however seems I don’t have the results from the LM
so have to go by memory.. and yeah seems to be 2k more points.also some of the games that used to push the temp into the 90s now only get to 80s so overall the machine is way quieter.
and did my wife’s machine as well… she does not believe in benchmark nonsense, I can hear its less noisy so running cooler

Glad you got it all sorted then! Performance will continue to improve minutely until it’s had a few thermal cycles, and then it should settle in and be good for as long as you use it if the fates allow it.
