OK i am new to water cooling and i wanted to do a dual loop system. Although i do not wish to mod my case and wish to keep it all interior. However the only setup i can figure out using the corsair 800D is a triple 120 in top section of case and a 120 in rear of case. I'm wanting to cool cpu and 2 sapphire HD 5870 video cards. Anyone have any recommendations on what i can do?
Read that link thoroughly. Read read read read read. I've been looking at watercooling since 2006, and I still managed to screw it up. Google around, get some ideas, then post back with your findings. It's a very different beast than air cooling, and you have to be very well prepared for it.
