Tags: Overclocking Build Intel i5 Fractal Design Last response: July 15, 2014 11:31 AM in Overclocking Share Jimbo832 July 14, 2014 8:39:48 PM If the build has a I5 4690k and a R9 290 and i want just those water cooled would a 240 Rad and a 120 rad be okay? otherwise a 2x240 Rads? I will be building in a Fractal design Arc mini R2 and don't want to go overboard .
