i received my Z9 mini 3 days ago, overclocked it to 743 about 5 hours ago, fan 100% (i dont care about the noise), temp of the cells is 58 celcius

so far i have an average of around 17 KH/s with peaks at up to 25KH/S


edit: also without overlocking it was around 11 KH/S, so it was pretty good even though it was running at 500
