The heat is absorbed into the mineral oil which is then passed through a radiator to cool it, works pretty well because mineral oil is about 5 times better at conducting heat than air
Didn't know that but did know mineral oil is better at temperature control then water so I guess it's a better option in a way, thanks for the knowledge
I wonder if they only part-way filled the case with mineral oil in order just to get that awesome bubble and vapour effect? Surely it would be better to completely submerge the entire thing for maximum cooling ability?
