and again Linus completely fails to explain what water cooling is and why its used, and uses misleading research and results to give the impression that water cooling is bad.
there's 2 things to water cooling. "series vs parallel" this refers to how the loop is setup
"Location" this refers to were you have your fans and radiator
in more detail: when water cooling what you'r trying to do is 2 things, A: MOVE heat away from the computer, and B: dissipate that heat in a timely manner at an optimal location.
firstly if you just need to cool normally, a normal computer then by any means use 1 water radiator or just radiator with fans.(even in that setup water is better, especially for gaming were hardware is not always working at 100%, meaning the temperature is stabilized, and fans can then work much better at dissipating the heat instead of regular radiator without water)
but lets say you are crazy enough to want OPTIMAL cooling, then you'd need to A: use long pipes that lead the cooling either outside or for those that live on the sun, in a cooling room.
secondly, dont make a fucking pipe and put each radiator in front of each other, put them in a grid next to each other so fans can work together.
and regardless of setup, water is always slightly better, but yes, setup matters but whoever wrote this episode(i apologize for being angry) is a fucking moron for not outlining this very clearly.
i want to see an episode were this is utilized to some extreme extend, or at least prove me wrong, because you cant.
