that's a S7, this is S9 thread, let's stay on topic as much as we can but much thx for sharing.
will monitor the miners closely.
Do you really believe that this can not happen with S9 ? I already sent one S9 B1 blade to China. Costs for me 70 euro.
Blade works maximum 2-3 hours since the arrival with lower hasheate. Fortunately, he was not burned. But I have some S7 boards with fallen off chips with radiators.
