The other one I tried was Kryonaut…that peaked at 52.8w for me.
Mind you, I’m not sure if the ‘freshness’ of the paste from their factory plays a part. My tube of MX-4 is approaching 18 months-20 months old (since purchase):
I would assume there’s some shelf-life involved…but not as short as 18 months (stored in a draw, under 21c). MX-4 has a 7 years applied / functional life span IIRC.
Also, I’ve since used the Framework tube on two of my other laptops…and that lowered the CPU temp in both cases as well (with no lapping nor increase pressure).
