I decided to test the mini 1 last time before sending it to Bitmain. I tested 1 hashboard at a time and and it turned out 1 of the board was causing the PSU to trip. After opening it up, found the burned hashboard. Mini is hashing fine with 2 good boards now. 3 other Z9s and 2 A9s in the same server case are running fine.





Server Case, it is vented on top with a 1500 CFM QC-ES-1500 fan.
