I am working on the fan problem at the moment. I have 3 fans plugged in. When it works it says 54 asic per board, but when not working on this controller it says 48 and 0 temp... On another controller it says 30 asic and 0 temp and all dashes instead of 0's

Its possible spaghetti code doesn't like more than 2 fans plugged into the controller.

doggie- do not write another BS comment.

I have eight double size S7 and they all show  four fan speeds.

FAN 40%

I ended up getting the 3 fans to show by plugging the 3rd fan in between the other two plugs. so plugs 1,2 & 3.

It is hashing now... but I am a bit sceptical because it doesn't explain how they just drop out randomly...

Fingers crossed... I have sent back a total of 7 hashing boards now... Not keen on another 3..

Cheers, I will keep you posted

Also showing temps at 0 and the wrong number of chips?

your photo shows a fan not two fans.

why ?  if your fans don't show the gear won't hash.

i had this issue as one of my fans was not plugged in.

once i plugged both fans in the gear worked.

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.
