I'd like to get Airplex rads in the future. I want my upper and lower Rad to be unified, without stacking them by interconnection plates. Instead, I want to use hard-tubes between both rads. My question is should I connect both Ins/Outs of both (facing) Rads with eachother? Or should I have one 'line' between them?
Im asking this because Im confused how the inner-Rad works; explained at pureoverclock.
