I have been having nothing but dramas with my antminer s7's. For the most part it's just been heat sinks falling off.

The current problem I am having with them is that one by one over time they just die. It starts with a miner mining for a few days and then randomly it will just stop mining.

I restart it, then it will happen the next day again. The the day after that it will happen about 3 times. Then the day after that I am lucky to get it to mine maybe 2 times for an hr or 2 and then after that it's dead for good.

I have lossed a total of 5 hashing boards this way.

It seems like I am the only on having this trouble.

I have tried the hashing boards on another controller with the same result. I have tried a different PSU. The temperatures are fine.

When I attempt to start the miner after this, this is what it looks like.

you are not alone in this. i'm searching everywhere for an answer to the same problem.

Both my S7s i purchased on batch 5 are doing the same thing. I have them running with 100% fan speed, and there is no way they are overheating as the whole area is very well ventilated (warehouse space). I'm running the miners on the EVGA supernova 1600 G2. And i'm not getting a temp reading on any of the 3 boards. Then the miner drops off, keeps beeping and the red light's on. WHen i check the miner status, i now get a temp reading of 127. I don't know if the heatsinks are falling off of not, everything looks in perfect condition inside. At this point now, i'm not capable of turning one of the miners back on unless i unplug the 3rd board. Then i get about 3TH out of it instead of 4.8.

I don't know what to make of it, customer service is slow on email, but i'm waiting to hear back from them after submitting as many screenshots as i could of the miner status.
