Probability ZERO as long as it is the current "top gaming card".
Be happy it's back in the $700 or a bit under range again, where it was in January.
Where dude?
Newegg - but I'm in the US, you EU types seem to get shafted on pricing due to your generally very high taxes like VAT.
My Aorus in the gaming machine runs at 65-66C under full ZEC mining load, not "about 70" - but it's in a case with good cooling in an air-conditioned environment.
I DO have it set up for 100% TDP, a mild core overclock, and my usual fan profile in Afterburner.
The Zotac 1080 and 1070 mini cards run reasonably cool, but they're at a lot lower TDP than a 1080ti has to deal with and all 3 models appear to use the SAME identical cooler.
I'd expect the 1080ti model to run quite a bit hotter.
