So i have recently gotten into bitcoin mining and i have 1 6970 and whilest mining it runs at 90-92 degrees (the max safe temp is around 110) and i was wondering how long is it safe to run the card at those temps continuously?
More aboutrunning card long periods time
Until it fails... I doubt anyone knows the answer to your question. It may outlive it's useful life or fail in a few months, no one really knows.
But will it be harmful to the card to run it at 90 degrees for 24+ hours straght?
It's not expanding it's lifetime i think. Can't you speed up the fan ?
