Have been playing with OS+ tuning. Anybody know the most efficient setting for temperature and power. I can get close to 75w/th with 1050w setting at 75C target temperature. This is with my best hashboards. I find higher temps I start to lose efficiency, but I do like the lower sound around 80C or 85C target temp.

I find with the power setting of 900w or less, efficiency isn't that great.
