So I re build the bracket that holds the minors inside the furnace.
It now holds x2 S9's and the results are good.
Sadly myb2nd s9 only has 2 functional boards, but performance was good.
Infact my basement where the test machine is normally quite cool, and after running 1 day, my wife was complaining that it was too hot 🥵
So room temperature was elevated to 27°C/81°F
Have a look at the video, would love everyone's feedback
