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.
People don’t water-cool their Macs.
I’ve never had the urge to overclock or water-cool or whatever in the recent past. No urge.
