Quick question:
Is it normal for an S7 to run hotter (~8C) than an S5, given the same operating environment?
Crash
Yes, I would call this normal. The S5 uses ~600 watts, the S7 uses ~1200-1400watts.
Thats twice the heat output from a same size miner. The S7 is then going to be hotter, given the same input/ambient temperature
