I am in the process of building a custom water cooling loop and I am wondering if I will have enough cooling capacity for my setup. I have an i7 5820k with two gtx 980s. None of my components are overclocked. Also those are the only three components that I plan to water cool. So my main concern is that two 240mm radiators would not be enough cooling for this setup. Should I be getting bigger radiators or is 480mm enough cooling capacity for three components? Any advice would be greatly appreciated!
