no.. this has nothing to do with temperature...
i think reading through this thread that there is enough evidence that sapphire shipped a whole batch of faulty cards somewhere at the beginning of this year.
Yet, I can't find any source on the internet where overclockers or gamers are having the same problems as miners. The cards only seem to break down with mining...
Is that just because mining is more intensive or is there more too it?
My dead gpus had intensity 19.
In Gamers case, they don't play 24/7 and always at 99% gpu load, so i think that they haven't problems by these reason.
