This was my first real small form factor build. For context, my first build was in an NZXT H440, then I moved to a slightly smaller Phanteks Enthoo Evolv ITX, and with this build, my goal was to have a more powerful system in the Node than what I had in the Evolv. The spacing was very tight with the GPU and especially the cables as you'll see in the pictures. I have yet to test the GPU under load however the Asus card does have two 4 pin fan headers on the end of the card that the two corsair fans are connected to which lets the gpu control these fans since they only affect the gpu which so far has resulted in a very quiet, yet still high performing 1070 doing very well. I've tried putting the gpu under load playing GTA V and The Witcher and even with synthetic benchmarks and have yet to see the gpu go over 73 degrees even maxing out games and all without me being able to hear it with headphones on while playing. The two corsair fans controlled by the gpu seem to be really helping. At idle, my cpu sits around 35/38 degrees (Celsius). and never goes above 70 from what I have seen. I have the cpu set to the Quiet profile in the bios and it's also running at stock speeds for now so it stays very quiet and and at very good temperatures. Cable management is a pain with the flat, ribbon cables that are included in the corsair PSU. I guess they really want you to buy their custom sleeved cables now instead. With a pair of headphones on while gaming i don't hear a thing and the system is only about a foot and a half from me on the desk. Very pleased with how powerful yet quiet this build turned out to be while being able to fit in a large backpack for LAN parties. Maxing out all my games at 2560x1080 60fps no problem with the CPU fan being the loudest component and overall the whole system stays very cool and inaudible with headphones on playing games about a foot and a half from the system.
UPDATE (7-21-16) So my first 1070 from Asus had a problem where the fans would only go to 0% or 100% and i couldn't control them, so I sent it back thinking it was the card, as my Gigabyte 980 G1 worked fine before that. I got my replacement in today and had the same problem so i tried taking out the motherboard and installing the gpu without the riser card and sure enough, it worked, i can control the fans as normal so i then tried re-installing the riser card it works fine now!
UPDATE (8-16-16) So now that I've had the system together for a while I've got a pretty good idea of how this gpu performs. I was optimistic for this gpu but it still surprises me. Idle, it sits at about 54 degrees with the fans off.In games after playing for a while, letting the card heat up, the gpu clock sits around 2ghz, somewhere between 1980-2012mhz, absolutely insane. Like I said never even going above 71 degrees. This card is near silent and I haven't even done any custom fan curves or anything. The Asus gpu for this build was perfect for to the two fan headers that allowed me to have the two case fans against the GPU for more cooling directly through the side ventilation.
