This my second build in a Nano S so wanted to see how much I could get into the small case. Being said, space vs. air flow was a challenge with two AIOs and their radiators. Originally, I planned to top mount the kraken and rear mount the hybrid cooler (both on exhaust) but the tubes where under too much tension (at least I felt like it) and I didn't want to come home to a soaked Titan. Putting the Hybrid cooler as a front intake cools the Titan VERY well and doesn't introduce too much heat into the case (CPU idles at 29c and 61c under load, a little warm, but fine IMO) CPU is OC to 4.5 GHz. With all six fans and two AIO pumps churning, this case is still quiet.
Titan X pascal Mod: Really not much of a mod, as I just removed the front/bottom? face, took out the screws holding the stock cooler, and slapped the GTX 1080/1070 Hybrid cooler on (super quick and easy) with the intention of taking out as few screws as possible (really, I didn't take the card apart at all, not even the backplate). I did attach copper heat sinks over the accessible VRAM areas to give them some added cooling as the card now doesn't tunnel air at all (it's wide open). VRM still cooled by blower and remaining housing. Attached the heat sinks with thermal tape (not permanent epoxy). It idles at 21c and maxes out at 47c under full load (huge difference from stock). This does make me nervous, messing with the card at all given the steep 1200$ price, but I'm hoping (wishful thinking maybe) that I can put it all back together and they wont ever know what I did if I had to RMA (although I'm not not counting on it). I haven't even tried to OC this card yet as I know it hits voltage limits and need to learn/study more about doing it. Haven't had the need to at this point.
Other than that, just made it look "pretty" with the Hue+ lighting, white paint, sleeved cables, etc.
To me, it looks good and runs even better. I got most ideas primarily from this site and took what I liked from various builds. Will likely get a big 4K monitor at some point, but got to space out the spending
