Just bought the EVGA GTX 1080TI , sold my 1080ti founders in hopes for better temps and noise
i am hitting over 70C playing ffxiv and the noise is almost on par with the FE but a bit quieter.
 
also doing unigen i am almost if not at 80C

I feel that the temps and noise levels are too high for the type of card it is. Unless thats perfectly normal . I did try custom fan curve and went back to normal adjusted my case fans a bit.
The core clock hits anywhere from 1920 to 1999hz and the temps are 72-75c in unigen is that normal?

Don't own a 1080 Ti FTW, I have a 1080 Ti SC and my card runs max at around 67 C after 3 rounds of Haven on extreme preset. 67 C is also the temp I get while playing BF1 at 1440p @144 MHz on ultra preset for about 2+ hours straight. I have a full tower case, a Coolermaster HAF X, that has  a 200 mm side panel fan blowing right onto my GPU. Also ambient temps in my house is like like 67 - 69 C. My CPU is watercooled with the radiator being a top mount (blowing hot air out of the case, if front mounted, AIO will usually blow hot air into your case). So your FTW temps might be a tad high but factors like case airflow, room ambient temps will affect your GPU temp a LOT. For all I know you like in Phoenix (seen the weather news there lately??) 

Cool GTX

I'm never going over to your place 67C        - I think you meant 67-69 F

 
HA! you are correct, 67 - 69 F, lol. 

I've got a GTX 1080ti SC Black Edition. With the load over 90 percent my temps are about 69 degrees C. While gaming the temps never go this high. I have a Corsair 780T case which provides a lot of circulating air.
