Those are some nice temps. How long has the miner been running in that screen shot and what is the ambient temp?
The unit has nine delta fans running at full speed 10 watts a fan or 90 watts.
If 70% works. Power would drop to maybe 60 watts.
Since my evga 1600 g2 does 1060 watts and 1730 h. With full speed fans I would drop to
1030 watts and get the 1730h
