Core X Series in Chassis Posted January 21, 2016 · Report reply Hello, I just got my first Core x2 case. I am attempting to setup my WC but I have questions that are not found in the documentation or otherwise. Helpful things I would like to know.. For starters I will be using 260mm rad on top with 180mm base - but i dont know which thickness to use for this rad. I want to make sure I buy the right one. Also the second rad is 360mm on left side with 120 mm based fans and I too need to know what is the best thickness for the rad. If anyone has any helpful info about this.. I would be most grateful. I will be water cooling the CPU, RAM, GPU, and motherboard. Also a side question. What would be the preferred size of the hard tube size, i was thinking 1/2 in diameter. Also what pump and how many reservoirs would work best as I do want to disperse the cooling among both rads/ I guess to better consolidate my questions. What is the maximum thickness of all the rad layouts for the core x2. This is not listed any where that I can tell. Any thickness will work it depends on what you do after that.I had a xspc 360 with just push fans but there was plenty of room for pull also. but i moved to a core x9 for more room. You need to check the rads to see what fans they need and so on Is this your first WC loop?
