Hi Guys I have trouble with my Inno A9 Zmaster fan speed. You can hear it rev up and down then up and down. So I checked the miner logs and it seems that the fan SET speed and Target speed keeps changing. What do you think is going on? Do I have faulty fans or is the miner faulty itself? I contacted Inno themselves but they cant find a solution... I would greatly appreciate if anyone have any sort of a hunch to begin looking at why this is happening. Thank you!!
