I know this is a noob question so be kind but I want to watercool my CPU but custom water cooling loops look intimidating and I have no experience with them so my question is about stock water coolers like the Corsair H100i CPU cooler for instance, are they tough to install? Do you have to fill and bleed them or do they come with the liquid in them? Can someone who knows more about water cooling than me explain the installation and set up process of a cooler like this? Again I know this is a total noob question, I've built a dozen or so rigs but I've always avoided water cooling because it seems complicated.
