what thermal paste did you use?
I only remember it was a beryllium oxide thermal paste as was mentioned on it's tube.

A white one, an "usual" one not cheap and nor expensive, bought ten years ago for this purpose.

Could be a good quality thermal compound that doesn't age quickly.
Maybe the need to replace thermal paste over time depends on the quality of a paste.

Certainly it's a good idea to apply a new layer if a heatsink was removed for any reason, otherwise a lot of air will be trapped.

Thanks for your measurements. Now you can test the same SBC when lying flat and standing upright like I did with M1.

Thank you for the idea, could be done!

And applauds for your investigation, interesting and very useful!

PS. And yes after detaching the heatsink from the chip its good to "redo", wiping the old and applying a new compound :-)
