Dear all,

I would like to water cool my HD 7990 (GPU only, cpu cooling unnecessary) with a big external radiator, because my case (Corsair 200R) cannot mount a decent radiator inside. The radiator has to be big (at least 360mm) because I might add another 7990/7970 later, and becaues 7990 has two GPUs.

Other requirements are to minimize the cost (best below 500$), and to achieve a quiet cooling system with the temperature below 75 degrees at full speed. I plan to order this

What else do I need? Could you recommend the other components? I intend to build a loop by myself. Thanks a lot.
