I have a burnt pcb too but mine can still work. I fix back in leaving a small gag without touching the heatsink.
I suspect that burnt portion is cause by the heatsink. The temp should be around. 48 to 58'c no more than. 59
Put a box fan or household fan right in front of the coincraftdesk where they are sucking the air . It shild be stable when. You got your replacement.
Thanks, Bitmine.ch are already sending out a replacement PCB / backplane for the one that is totally burnt out which is a really good turn around (Already received the tracking number from UPS).
I'm waiting to hear on the other broken PCB as I don't think the ticket updated last night so have opened a separate ticket.
On another note, the final miner out of my order only has four out of five working ASICs and crashes with a segmentation fault after a few minutes.
