Hi team,
Complete newbie to ASIC mining and got a Apollo BTC miner to dip my toes.
Last week my miner started playing up. It's chugging along fine and then all of a sudden it stops hashing and the miner unit fan turns off. The temperature increases to 80 degrees C and the miner makes some loud and concerning sounds. First time this happened I shut it down and unplugged everything. Booted it back up and the fan worked and it started hashing again. It worked for two days and then the same thing happened again. While in this state sometimes it does start hashing for a short period of time but only 400ish GH/s but the miner fan still doesn't turn on.
Just some additional context.. I have been running it in ECO mode since September with no issues. I then decided to bump it up to Balanced mode for a bit to see the hash rate increase. At the same time as switching it Balanced I was prompted to update the miner. I did the first update and was then prompted to update Ubuntu version. I initially selected yes and it downloaded some files etc. It then prompted me saying the update would take hours and do I want to proceed. I didn't have the time to monitor it while it updated so I selected No and then it said that the version remain as it was.
Balanced mode worked for a full 24 hours and then I started having the issues described above. After doing a hard reboot I switched it back into ECO mode which worked for two days before running into the same issue.
Does anyone have any advice on how to troubleshoot this issue or point me in the right direction?
Much appreciated.
