Thinking about putting the Coolit Domino into the Antec 902, but it would take the back 120mm fan along with it. I don't think it would make much of a difference, and I might add a fan to the side panel. Just wondering if that back 120mm makes a huge difference, especially with that huge exhaust fan on the top. Thanks for your thoughts/help.
It will not effect the cooling performance of the Antec 902. It simply replaces the back 120mm fan with the radiator, which contains a 120mm fan. It performs in the same manner by sucking air though the radiator (cooling it/CPU) and blowing it out the back. This is the same thing the case's 120mm fan did with the help of an air cooled HSF.
