Have the same overheating problem last night. I have two Apollo miners, the newest of them have been running for 30 hours this week and got overheated, FAN and LED in red stayed on all night but not mining and it was flaming hot until this morning. I pull power off and let it cool,

It is back up and running now. I have not changed any settings still running on the factory ECO settings. Should I leave the fan on at 25% or so all the time? any recommendations?

Thanks!
