This is exactly one of things I don’t like about PCs: Unnecessary maintainment.
Are you calling proper water-cooling “unnecessary maintainment”?
Yes. Why should I have to care about water-cooling? It should just work.
Do you understand how water-cooling works? It doesn’t matter if you’re using a Mac or a PC, if you don’t do it properly, you’ll probably get all your components wet and your computer will be wasted.
EDIT: I assumed you meant the water-cooling should just work. But yeah, what he said. Water cooling just works better.
