You can see my Troubleshooting guide for older Avalons for reference (link is in my signature space). Good cpu paste will do.
Great, thanks a lot. I was waiting to hear back from Canaan before opening anything up, as I followed up with them with latest logs showing that same ASIC running at 120C... well...
Latest update:
That same chip is now showing 180C+ (Sometimes 198C!) for same voltage in the miner logs, and Canaan replied back that it is most likely a false positive and everything is fine (but pretty sparse details on their end).
Could this be a false positive? Wouldn't 180C melt the PCB?
