After long time one of my AMD cards crashed.
I had -tt 55 -fanmin 55 -fanmax 85
And log crashed shows me that fan was 0
I suspect that temperature was too high (though was night) like 58-60 degrees and having fanmax 85 coupled with undervot made the miner crash. Is it possible ?
It is a pity that you deleted the logs of the miner. You must first understand the reason for stopping the cooler. Since the miner was set quite low limit temperature (tt 55), but the graphic card still overheated 85+C means the miner has not worked out the setting for the turnover of the cooler. I recommend using a third-party program to adjust the speed of the cooler. For example, OpenHardwareMonitor. MSI Afterburner not recommend because often he himself crashes.
