Good day to everybody,
my test was done on my Framework Laptop 13 AMD (delivered 1st week of January 2024).
To be honest, I was a bit skeptical, but the test results speak for themselves (2 pictures say more than a thousand words 
I bought the PTM 7950 pad (30x20*0.25mm) over ebay for €11.52 inclusive postage (a Polish dealer delivered very fast to Germany within 4 days).
The most work was to clean the processor; wasn’t sure whether leftovers of the stock paste hanging at the capacitors could influence the stability, so I used Isopropyl alcohol, Q-tips and the included brush to clean the top of the processor. BTW, its die size (AMD 7840U) is 16mm x 11,5mm. This means, the (smallest) 30x20 size of the pad is enough for 2 applications.
with stock paste:
with PTM 7950 pad:
So to make it short: The pad works! 
And I got the impression, that the fan operates less.
Because everybody knows that the lifespan of electronic components increases with lower operating temperatures, I can’t understand why Framework isn’t using that pads in its production as a standard (like another big laptop manufacturer is it already doing).
