For a little while, the AC in my apartment was out, thanks to a fuse on the roof. :/ During that time, I set my rig outside, because the first evening the inside went to 125F / 51C, and everyone inside was camping out in our rooms with a balmy 105F / 40C. Mind you, I’m in Las Vegas, one of US’s deserts. The outside temp was measured to be 115F / 45C during this time. My cards would rise very quickly, and I had fans on 100% during mining. Cutoff was at 90C after everything was said and done, as it still gave me a 2500 Kh/s average, as opposed to a 1900 at 85C.
Thankfully, it was only outside for 3 days, and it only halted once because my ISP was and still is having overloaded peer relays. My rig is now sitting nicely at 2900 Kh in a 75-80F / 25-28C room throwing 73-83C. :) I’m going to get a better fan as it is.
