I have a W2 which I love, but am having a quandry about the best cooling set-up. I currently have an AIO front mounted as intake, x2 120mm fans at the bottom, also intake, and a single 120mm at the rear as exhaust. I have a reference 980 so that's exhausting out the back, therefore not dumping any hot air in to the case. This seems to be the optimal cooling config for the W2. My big debate though is with the upcoming 1070/1080 Nvidia cards. I plan to get one of these, but Nvidia have priced the Reference (Founder's Edition) cards sky high, so the non-ref cards are going to be cheaper, faster out the box, quieter and cooler... would getting one of these really be a bad idea for the W2? Has anyone tried a reference GPU vs non-reference in the W2 to see what difference it makes to internal temps?
