Greetings!
 
I had originally purchased a Ti Founders Edition and bought the Hybrid kit along with it.  After mistakes were made, probably mine, I completed the installation and my card would just not power on, regardless of what I tried to do.  I RMA'ed the card and returned the kit, not wanting to try to build it again, and destroy it...again.  My replacement Founders Ti will soon go up for sale, because I still REALLY wanted the Hybrid for this particular PC build.
 
So, rather than test fate again, I purchased the 1080 Ti SC2 Hybrid.  I finished the install, and just as others have noticed with the Hybrid kit, the SC2 Hybrid is the real deal.  This card is installed in a smaller case with limited airflow.  In benchmarks or gaming I see a max of around 45 C, that's crazy!  I haven't tried overclocking it as of yet, but my assumption is that there is a lot of headroom left in this thing!  Default in benchmarks the GPU core jumps up to around 1860-1950 Mhz, so it is not wound as tightly as the FTW3 is (FTW3 defaults to 1987 Mhz for me).  It is QUIET, no pump noise that I can detect, maybe a little coil whine when benchmarks push FPS past 500, but it is barely audible and can't be detected when my ears are further than 12" from the PC case it is installed in.  I did notice some weird artifacts when I first tried the Superposition Benchmark out, but after the 1st run they went away. 
 
I am not sure how many out there have purchased this particular model, so if there are any questions, feel free to ask!
 
P.S->  I have now owned a EVGA Founders, FTW3 (in a different computer with a lot of air flow), and SC2 Hybrid during this generation of cards, me likey the 1080 Ti!!
 
 

Glad to hear you enjoy the cards! I swear by the Hybrid cards as well, they are my favorites. 45º C under load is really good, I usually see about 50-55º C. Update us on how the overclocking goes. I am curious to see what you can achieve with that.

Also have an SC2 Hybrid, usually average around 52c in my NZXT H440 case, better temps than i was getting on the 1080 Hybrid. I do notice a little bit of extra noise coming from the fan on the GPU itself when i game but it's relativity small so i'm happy.
 
I'd maybe like to experiment with undervolting the card, to further lower the temps.

The cooler the better. GPU Boost 3.0 will downclock slightly starting around 40º C (although this varies per card) but the increments are very slight. You should be getting very solid performance at 52º C!

Excellent, I've actually got a question: I'm trying to build an ultra silent machine, since I do 3D modeling and prefer a quiet and peaceful atmosphere for my work. Since you've got experience with the FTW3 in an air-centric machine and the Hybrid in another, which would you suggest for somebody that places peace and quiet as a huge priority. Fyi: The GPU would be under load with live rendering much of the time, and if I got the hybrid I would definitely be swapping the rad fan and setting a custom fan curve via motherboard. Ty!!
