I'm about the buy a haf x, and at some point i wanna try out watercooling but it'll be a first for me. What I'm wondering is when you mount the radiator in the top of the case, do you use the case fans on the top as the 'pull' fans for the radiator and just have push fans mounted to the bottom of it. or do you have more fans ontop of the radiator pulling then exhausting out through the case fans?
