You killed that 1070 yourself, I wonder how you could be comfortable with your gpu doing 95°C temp, it's surely going to die very faster, I get worried even if my cards hit 63°C I always have to crank the fan speed up to drag the temp back into 56 to 60°C Max but yes 70°C is the safest temp for nvidia graphic cards
I didn't kill it, it tried to commit suicide.
The fan spun off it's spindle. The the card thought the fan was spinning, as it got hotter it just kept spinning the fan motor, that was attached to nothing, faster and faster.
It hit 95 and shut down. Cooled off and repeated the cycle. I was remote at the time and all the other cards in the system were fine and according to the monitor the fan was working so I figured it was just a sensor error.
When I got in and found the problem I figured that is was dead. But, 1 new fan later it was back up and running for a long time after.
