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 ?

Permanent LINK:
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.gz

May 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.

Which version is "original firmware" ?

When you install other firmware have you UNchecked "keep settings" ? ? ?
