Have you looked at your kernel log? You can post it here for us to look at. Please use the # feature when posting code.

More times then not, if the miner is mining for a short time and stopping it has something to do with your power supply. Please give us some information on your power supply and the circuit.

Both fans will spin on a S9 due to suction. This does not mean they are both working properly. Unplug one fan and then the other and find out which one is not registering. Swap the two fans connectors to find out if it is the board or the fan. It should be showing 2 fans. I have had miners only show one fan and/or 0 hash rate due to insufficient power.


In the logs its saying that the temp was too high. Even though the unit was never hot. But I wondered if that was due to it only having 1 fan.
I swapped the fans and both seem to be functioning now. Not sure why or how. But they're both actually working and both actually showing up now.

Just wondering. Why was it shutting off before from just being in the high 90s and low 100s? I thought the shut-off temp was like 115. As far as I know, it never hit that high.

Anyway, I changed things up a bit. I put a AC unit in the room with the antminer. Now everythings sitting around 76 - 82~.

Everything it seems to be working fine now with the ac and now that both fans are working. It's been mining constantly for 15mins now. So I think everything is good Smiley

Thank you!

You realize those temps are in Celsius right? The poor thing was burning up!
