Just so everyone is aware of what they're looking at, Kryonaut currently holds the tile for best performing conventional non-liquid metal TIM. It even outperforms the fabled GELID Solutions GC-Extreme: the newest "recommend for every build" TIM.
To quote Overclocking.guide:
"After almost 6 years in lead of the market, GC-Extreme lost the battle against the new Kryonaut from Thermal Grizzly (talking about conventional paste)."
This stuff is very, very good and very, very hard to get a hold of.
Here are the results of the top five TIMs tested out of around 50 of the most common/less common TIMs on the market.
