Which is the ideal temperature board for BitMain S7?

At 60C i get just about full TH/s, about 5-10GH/s "loss". At 45C i lose another 10GH/s. So i like to run mine anywhere between 45C and 60C. I would tolerate 60-65C on bad days, but i really do not want 70C+.

Some people run these at 80C fine, though.

So far I find around 60 is the best for low hw rate and full hashrate.  i get 0.003% error rate at 60-63.  But sometimes it "creeps" up to 0.01%, so I restart it and it goes back down.

At 80c?? For how long? It must run 24/7

I push all my s7s to about or just under 60C and they mostly run at 5Th/s, any faster than that and they either get too hot or fail and I need to do the sd card reset.

Grn, your ambient temps are pretty low. Is that ~5c?
