Watercooling Overclocking Help
Watercooling Overclocking Help
The situation suggests a 240mm radiator intake and exhaust, which should suffice for cooling a Ryzen processor along with two graphics cards.
2 x 240mm rads are sufficient for a Ryzen 7 and two 1060s in SLI + overclocking. Avoid slim rads and low FPI. You'll need to be ready to hear your fans, as you won't be able to run a silent system.
What Ryzen CPU model are you considering? Which type of GPU should you have? Will you be increasing the clock speed? Are you concerned about the sound output?
This approach is fairly reasonable for building loops, often getting you close enough, but the optimal method is to determine the total loop TDP and assess what you can realistically produce in total power.
