Could be an issue with the temp sensor. It's weird that I've tested seventy of these things and not seen any problem and you've got two of them doing the same thing. Usually when multiple anomalies coincide I start to question the user before I do the hardware.
I'm guessing you power-cycled the miners and the issue persisted, otherwise it'd be barely worth mentioning...
Yes, I power-cycled the miners. I'm not an expert in mining hardware by any stretch but my line of work is electronics, specifically avionics systems. If there is known voltage/amperage/resistance at specific points that I can check for that will perhaps help in identifying the issue just let me know.
I know my way around test equipment, just not code or command line. Nine of ten times I suspect PEBKAC as well, just because I know me. I'm still hitting ~2.8T with all four I just want to make sure that I'm not causing damage to the units.
I ordered the temperature sensor that @phillipma1957 suggested so I'll have some definitive data on temps tomorrow evening.
