Dude, set aside an evening and skim through the s9 thread. You have questions? ALL been answered multiple time in there....
Hey sorry about that - I did searched a lot, but all posts I have discussed the PCB temp, and I don't have that on my antminer. Similarily, they said around 60 degrees was better but I don't have chip 1. Other than that, I am concerned about fans running at 6,000 RPM at all time.
Anyway, thank you all the answers!
