One of my units experienced temperature cut-out I think.
It was hot to touch and not mining, miner offline and fan not spinning. This is a second time this happened. I power it off, after few minutes plugged back in, it started mining just fine. I am running Eco mode with Auto fan.

I really think we need to get Minimum fan speed option on Auto mode, so temperature is controlled in more stable way.

For now, I changed fans in both units to manual mode at 15%. It's still quiet and stable. Temperatures are 52-52 C instead of 70 C in Auto mode.
