i checked the fans and one of them is broke, there is some plastic missing and some broke, so i think thats why,
can be that the problem that doesnt mine ?
OF COURSE, I mean the kernel log is telling you that there is something wrong with the fans, and then you see a broken piece on the fan, what else do you think the problem could be? there is no work around, you need to replace the fans and ONLY then troubleshoot further if the issue persists, but before doing that, you are just wasting your time.
Would you mind to try to flash it with BraiinsOS?
Since when did BO start to support this kind of mining gear?
Well, i buyed a new fan, but for antminer, the same voltage, DC 12V 2.7A 6000RPM de 4-Pin Connector for Antminer S7 S9,
and the fan rotates but it is showing me 0 rpm, i'm trying to find the exactly same as my old one, because as i see, even if it's the same conectors, the antminer fan doesn't work for Aisen A1...now the Cgminer Log is showing this:
