My 1080SC blew out, started with a black screen and crash a few times then all the card did was the leds flashed off and on then I removed it reinstalled and had nothing, tried with another PC and card was dead, wasn't a PC issue my 980ti works perfectly fine in it. I did the BIOS update but didn't have the thermal pads to do that. Nothing overclocked on it and I even had precision running at aggressive settings.
It's hit or miss on failure I think, I never had any heat issues
