Came home from work today, and the miner had timed itself out. No big deal because I Restarted my miner and it was up and running again no issues. Only thing is now it is starting to make an awful sound every couple seconds. I have a feeling this noise is coming from the fan since it is a moving part. has anyone else run into this issue yet? If so what is the remedy. Should I safely stop the unit from mining and safely shut down the node till i find the culprit or is it safe? Operating temperature is fine. Everything looks great besides this weird sound. have been running in ECO mode since the unit came online. Haven't messed with any settings. Maybe something is coming loose or starting to?? Any help would be greatly appreciated!
