You would need an enormous amount of energy to achieve 0 K (-273 °C). See the system here is the atmosphere so you can think about the average outside temperature as the “state of least energy”. So you actually need to use a lot of energy to achieve that because you are going way further (although in the other direction- negative temps). Our system is earth, so 0K ain’t easy chief - check quantum computing (we need almost 0 K to work and those are huuuuge resource intensive machines). If you were in between the emptiness of galaxies, then that would be indeed the “normal default” which entropy would “go towards “. Basically, “our” entropy has a different temperature goal, because we are the system that is fed and bound to the sun. I can’t explain better because I also have limited knowledge, just the basics, sorry. Also the “” is to explain better, do not quote those as scientific.

You can’t output more energy than the one available in a system.

The real solution to cool off cities is trees and less pavement :)

Its not so much the card itself, its the price and false market around it (2 versions to trick the average buyer, one with literally double the memory). Also its a downgrade from previous gen now cheaper 3070. Its corporate greed with purpose misleading. If the card was 100 € cheaper, it would be actually really good. I think that is the census on reviewers like GN but don’t quote a random dude on the Internet ahah
