I have a Corsair 600t. This is the first cutom loop i've ever done so i dont have much to go on. My plan was to place a 240mm in the top, a 200mm in the front and if needed a 120mm in the back(although i'm not sure if that will fit without putting the fan on the outside). Summer is killing my 290s with them hitting 95c in Xfire even with the custom MSI twinFrozr fans at max. Also can anyone hazard a guess of temperatures i could expect. My Fx8350 would also be in this loop, but its not massively overclocked (4.3ghz bad OC chip) thanks
