Hi I have recently purchased the NZXT Phantom 530 and the Corsair H80i CPU Water Cooling solution however I'm a little unsure about the installation process for the Corsair H80i. Should the radiator (120mm) be installed at the top of the case or somewhere else in the case? I have been reading the manual and its very thin on information but mentions that the top of the case supports 120mm * 3 or 140mm * 2. However looking at the youtube videos, I have noticed that everyone seems to be installing these AIO coolers at the back of the case? (but they are using different cases). Some guidance/recommendations would be greatly appreciated, as this is all new to me and I have never installed a water cooling setup before.
