So since I built my pc back in 2016, I've used air cooling to take care of my cpu. Recently however, I've put some thought into switching over to liquid cooling, mostly due to the low profile and softer noise. I always thought they were a hassle in the past, but honestly I know almost nothing about them. So all im asking for is the need-to-knows of liquid cooling. Specifically: what is a good model to sit on an i7 8700k w/slight OC, what sorts of fluids are used in water cooling, maintenance, and all the basic components that go into it.
