This build started simple enough and then morphed into what it is today. Cooling the dual 1080ti's offered a bit of a challenge until I put together the dual loop, separating the cpu and gpu custom loops. I also encountered plenty of opportunity with the Corsair 570x case and adequate airflow. The original layout, even with the two separate cooling loops, still resulted in some serious heat issues. I ended up setting all fans to exhaust and created a completely negative airflow design. I have researched positive versus negative airflow, and have plenty of experience with this setup, there is no need to comment on the fact my front fans are backwards. I understand, but sometimes you simply have to do what it takes to keep your rig temps at bay. I am happy to say the system runs cool, quiet, and is a pretty nice over-clocker.
