In my experience, do not change tubing diameters unless you have to, if you can, go to a hardware store and get converters, and if you do go water cooling do NOT USE WATER!! can be hazardous and can build mold/fungus/nasty stuff. Get a non-conductive liquid if possible, Fluid XP or Feser one work really really well and they have a higher temperature threshold, and are non-corrosive
