I'm kind of surprised at the heat these things put off... I've got three in my garage and this morning they had chip temperatures of mid to upper 70s. Not many HW errors, but still too high for my comfort. I was hoping the cooler autumn/winter temperatures would help, but I may have to address cooling needs now.

Anyone come up with clever solutions for cooling?

I'll look into that. So far, it resolves itself... after about 60 seconds it changes from the socket error to the hardware version info... and the mining commences. Thanks for the update on the latest firmware. I'll try September's.

Yay! Hopefully this addresses my hashboard and "socket connect failed: connection refused" issues. I was considering rolling my firmware back to the September version. Anyone have success either way?

I'm getting the same thing, only with my 2nd board. Actually, it had disappeared for about 4 days... hashrate was still in the 18-19 range. Then two days ago, it reappears... Anyone else with this nonsense?

Is there a minimum amount of NDC for proof of stake?
