Hey
Got a z11 used , it worked fine 2 month but now keep giving me a to hig temp on chip 111 close pic need reboot and stop mining until i reboot , after 2 min it will stop again.
Does it just need to be open op and maby remove dust?
If there is dust, then it is better to clean it, but I doubt that the fans do a poor job. Check the operating frequencies, if the ASIC is overclocked, then restore the factory settings and set up the mining pool again. Try to lower the frequencies, use an interval from 650 to 700.
