looks like one of my miners is having problems.
I power it on, it starts hashing just fine, fans work, etc.
At some point, the fans start running slower and slower until they show 0 rpm's and then heat rises. And then temp cutoff. Once it cools below, the fans kick back on and the whole process repeats itself.
Anyone know what to do about this?
Had exactly the same issue - I think it is wrongly wired thermal probe. Solution was to disconnect the probe from the pcb. Obviously not ideal, but works and gets them mining. You could possibly adjust the fan speeds using the various CGMiner configs, but I couldn't get them working.
