Hello everyone,
 
    So I got my GTX 1080 FTW two days ago and to start off I would like to say its pretty neat. So I threw some benchmarks against it so I could see how it was performing out of the box. From running Valley Benchmark for about 20-30 mins yesterday my temperature were about 71-74c which it mostly hovered around 72-73c with the fan speed ~40%. From playing Rise of the Tomb Raider and Dying Light my temperature it was about 74-76c with the fan speed ~50%. As a result of my temps, my clock speed drop from 2025 and settles at 1949 Mhz which is kind of expected. Though I have notice it might go back up to 1962 Mhz. I haven't over-clocked or tweaked the fan curve yet but I was interested in knowing what other owner's temperature and / or fan speeds are. 
 
Sadly I don't know the ambient temperature of my room but my case is Corsair 750D Airflow Edition and I don't have any cables blocking any of the fans. Nevertheless thank you for taking a look at this post!

Your temperatures seem quite good. I didn't try the default fan profile for my card, I just determined what fan level is unhearable for me (68%) and set my card up to operate around this level.
 
My temps are usually 66-72°C with the fans spinning at 66-71%. I got the Nanoxia Deep Silence 5 case packed up with fans (4*140mm case fans @1100 rpm (one at 800) and a watercooled CPU with 2*120mm with fans at 900-1200 rpm), almost no cables blocking the airflow. I got it overclocked a bit (45 GPU / 150 memory, 115% Power Target) and my clock speed is between 2012-2063. Oh, and it is almost completely silent, I only notice it when I close the window and listen for it.
 
Hmm I'll just run some Valley now to get a good reference point for you ;) It's also a bit more warm than it was yesterday when I checked my temps with the Firestrike benchmark that also gets really close to the temps (maybe 1-2 degrees difference) I get while gaming.
 
Oh, pictures of my build are at my mods rigs page ;)

Ahh cool, I'm going to try to over-clock my card over the weekend. Hopefully I'll be able to get my clock speeds above 2 Ghz. Fingers crossed.

/edit : Just finished 30 minutes of Valley and it seems to be the least demanding benchmark I ever ran xD 61-67°C, with a maximum fan speed of 68% and a  maximum TDP of 83%. Clock speed settled at 2038, sometimes dipping to 2025 MHz after reaching 67°C. I think Heaven is better for temp testing, it gets 1-2 degrees below Firestrike, and thus gaming performance, IIRC.
