I already knew all of what you said.
Maybe we can contact AMD & Intel and ask them if they can make their CPUs get as hot as a gas engine LOLOLOL (Joking)
Yeah water coolant for lower temps. Glycol for higher temps or mixed metals.
eventhough just jokingly.. good point though..
I wonder will there come a day where some SUPER chip will require some more serious cooling. well, they need a breakthrough on silicate technology to raise the melting point first.. but for some reason.. I actually see that a possibility in the next decade or something. hehe.
