What do you guys run you cards at in the summer? What is safe 24/7? Mine ran nice and cool in the winter but it's warming up now. Have too many cards for AC, so I use exchange with outside air. For 1070ti's and 1080ti's
Nvidia cards mostly getting high temperature than the AMD cards. Maximum you can allow the Nvidia cards to touch the 79 degree temperature mate not more than that. If you air conditioner in your mining rig set up room then it is much better to maintain the temperature.
I have each 10 cards rig in 3 numbers but they are not going big temperature as you think. I have one 1.5 ton AC alone in my room. Still no issues for me mate.
