These readings show the miner’s actual condition and can help you act early, saving time and money. In many cases, you can diagnose an issue remotely instead of visiting the miner. For example:
Higher fan speeds may indicate that a miner is overheating; you may need to change its operating mode or conditions.
A drop in hashrate may indicate a faulty board.
A fan stopping may indicate a malfunction. You can then decide whether to address the issue on site or take the miner to a service center.
