No, but really, i cant imagine running cards for more than 6 months 24/7 at that temp, i dont do over 60, and thats just the "one hot card" that usually happens.
50° is my usual, makes for long life, is 7% hash really worth almost 30°? DAMN :/
I have 280x that are still running @ 80c after all those years (yes, 24/24, 7/7)
And if you take a look at the back of the box of some 1080Ti FE, it says they are built to run 24/24 7/7 @ 70c for ... 10 years (maybe 12 , I have the boxes somewhere). I doubt the fan would hold ten years but Im pretty sure the memory and the processor can last 10 years with proper cooling (aka replacing the blower after a few years).
Good but have you free electricity?
and your point is ?
