mine are flawless. most likely you all over clock them. or over power them via tdp
Many people think 110% and a high clock is okay.
the answer is it is not okay for these cards
what are your tdp settings?
80% = too high
70% = good
They all were at 65 - 70% tdp, never exceeded 75 C. I don't buy this explanation. On the contrary, ASUS 1070 Turbo @ 75% tdp are working fine since almost 2 months.
