[coreboot] Lenovo T420 Question

[qma ster]

Actually there is an even better non-conductive thermal paste (not liquid
metal) than "Grizzly" --- it is called " Gelid GC-Extreme ". Here is a
comparison from one review website that I screenshotted -

between them is not big, but I think in your case every degree counts.
Also, there is a packaging of Gelid GC-Extreme that is 10g -

, this larger packaging gives a very affordable price per 1g and will last
for a long time ;)
