Any info on problems with fan speeds on the s9? Got 3 hooked up today, been running 4.5hours now, and one of them likes to ramp up the fans to 6k rpm even though the temps are fine. Maybe a bad firmware? Also one of them is throwing .266% invalid/stale shares but this is below the pool avg so from what I understand thats pretty normal and will level out as I complete the ramp up period. Thanks for the help
