[coreboot] Lenovo T420 Question

[i1w5d7gf38keg at tutanota.com]

Could you try out "Thermal Grizzly Kryonaut" or even liquid metal based products and report about the temperatures? It would be great if you could try out first the Thermal Grizzly Kryonaut and later then for example the Thermal Grizzly Conductonaut and report here.

Please clean up the surface before applying when possible with https://en.wikipedia.org/wiki/Isopropyl_alcohol (its cheap and easy to get).

>> used to have a 2720m which worked without any issues AFAIR, but the 3740qm effectively gives me double the cores that are a little faster.
