I am running an EK Waterblock, so that most likely is helping, but I was able to get a stable (2 hours stress testing) clock of 2126MHz and Memory @ 5500MHz with my SC. I only had it installed for a day to test it, as I am in the middle of a new build, but plan on playing with the voltage a bit more once completed to see if I can kick the clocks a tad bit higher. Temps never got above 45C.
I have more info, pics, and benchmarks on this tread I started last week.

that does, indeed, look pretty awesome. makes me want to consider watercooling my 1080 FE.
i'm a first time OC'er, so still learning from reading u guys' posts. i just downloaded MSI Afterburner this morning and started to mess around with my Founders Edition 1080 for a bit. i wanted to push it for a little bit with the Unigene Heaven benchmarks because of some of the temp horror stories i've been reading.
right out of the box, on stock settings, the card boosted right up to 1911 during the first benchmarks. i was able to get the card's clock speed up to 2139 and about +350 (i forgot the actual offset) on the memory. the benchmarks started crashing after i put the memory up to around +400. with the fans on 100% (for benching purposes), the card hovered around 60*c to 63*c. i'm pretty happy about that because of some bad reviews stating temps in the 80's+.
my MoBo already auto OC'd my CPU to 4.6GHz, so i'll probably be gaming with my GPU @ around +50 to +75 on the clock speeds and about +100 to +125 on the memory clocks. i've already set a custom fan curve in Afterburner and it's keeping my temps in the 60's while staying fairly quiet. the GPU doesn't really get noticeable until the fans ramp up over 75%.
all in all, i'm pretty happy with the purchase. i just hate the damn green lettering because it's throwing off my white color scheme!!!
