I'm looking at rebuilding my setup in a Fractal Designs Define R4. I'm looking for keeping things as quiet as possible so I was tossing around the idea of using 2 dual 140mm rads. I know that I can easily mod the front intake to handle one rad but I'm wondering if anyone has mounted one into the top opening. Fractal says that 2 140mm fans will fit but I don't know if the fans + rad will interfere with the ram slots. Has anyone tried? I won't have the case for a few days so I was going to get on ordering the new rads so I have everything at about the same time. I don't have a lot of options for rads here in Canada unless I want to pay ridiculous amounts for shipping. The two I have available to me are the XSPC EX280 and the EK-CoolStream RAD XTC (280). I was thinking of putting the EK in the front and the XSPC in the top since it is slimmer. Thoughts, suggestions, proposals, salutations and sandwiches appreciated.
