Best to have the rad for the GPU as an intake though since Pascal deals with boost clocks via temps and that would net a few degrees cooler at the expense of a few degrees on the CPU.
I was thinking about getting a h75 and then because its a 120mm rad fan size & putting that as an intake on the bottom 120mm fan intake. So did you have your gtx 1080 on an aio? what kind of temps were you getting?
