Since they are authorized by zeusbtc then I would still trust them, what the main branch says does not really contradict with what the branch in your country told you, it only weakens the probability of the latter, also I must make clear that it's not just because I tend to trust the main branch more - I base my points on that alone, it's more like common sense, what the Chinese branch said has much higher probability of happening.


Indeed, you are right, it's very possible, however, it's unlikely, the way the board is designed should not let a single sensor stop the other 3, the proof is we are aware of some hash boards that work with less than 4 sensors, which means the probability of a single sensor stopping all others is kind of low.


Yup, your problem is power related, I am 99% sure it is, and let me explain why:

Reason 1:

You now have a total of 12 (3*4) broken sensors, does that make sense? NO

Reason 2:

You have at least 1 bad chip/heat sink on all 3 boards, how possible is this scnerio? i would give it  1% at best, provided they all failed at the same time.

Reason 3:

Something that has an effect on every aspect of the miner, we have two things, the control board and PSU, from the various reports and personal experience I doubt the control board will cause such an issue, so what is left? the power supply.

I would still suggest that you flash the recovery file using an SDcard, and then flash another firmware, see if that helps,


This actually adds more strength to the power supply being the issue, the sensors are designed to work at temps between -40c to 125c, it doesn't make sense that  10 or 15 degrees change in the ambient temp will make them work or not work, however, a 10 degrees change makes a world of difference to the PSU and the chips, I am suspecting that your PSU is overheating at noontime and fails to deliver the DC voltage needed by the boards, also during peak hours the voltage at your house/farm might actually drop to below 200v and thus causes the miner to not hash, make sure you measure that too.

If you have a spare PSU, I suggest you try it, or at least measure the DC voltage coming into the boards from the PSU



4 sensors 1 board, the other two boards were fine and reading all sensors, so it's a bit of a different issue from yours.


overclocking has more effect on the chips than on the temp sensor IMO, so it's more likely that some of the chips got toasted, you can test them with a multimeter by the way.


That's an excellent idea, even when the PSU is having some issues, going with a lower frequency might fix it.
