i have got the same problem with my batch 3 mini.
Once i install an other firmware the temperature sensors dont seem to work and the fans always spin on 100%.
Does anyone have the same problem and does anyone have a solution?
Thx!
Have you installed firmware for z9 mini ?
Have you installed this firmware version ?

Z9 mini, Batch 1 stock firmware (the first original firmware downloaded from Bitmains support-site), will be permanently available at:
http://releases.broked.net/antminer-z9-mini-201805262047-500m.tar.gzMay 26 version and Aug 31 version are the only versions as far as I am aware that have been able to download for z9 mini from Bitmain's support site !
Have you carefully jiggled fan cables in connector on controllerboard or tested move fan connector to fan connector nr 2 ?
Hi,
it works just fine with the original firmware, so the fan cables are not the problem (nevertheless i checked it and also switched to the second connector).
I tried batch 1 firmware (the one you mentioned), result ----> works, stable overclockable until 681
BUT:
Chip temperature always reads: 0
Fan always spins at 100%
Changing it to 50% works for 10sec then back to 100%
Also tried batch 2 firmware, same results.
I also tried to unplug the fan while the miner was running and connect it to the 2. fan connector of a other Z9 mini but it stops working the moment i unplug the fan.
