Re: Bitmain launches the Z9 Equihash miner

I think I broke my Z9 Mini.

The fan is not getting recognized anymore:

Oct 11 21:36:21 (none) local0.notice cgminer[1335]: No Fan find, check again
Oct 11 21:36:22 (none) local0.notice cgminer[1335]: No Fan find, check again
Oct 11 21:36:24 (none) local0.notice cgminer[1335]: No Fan find, check again
Oct 11 21:36:25 (none) local0.notice cgminer[1335]: No Fan find, check again

I worked with a fan faker before the miner is not even responding when the original fan is attached.

Is there a work-around to disable the fan check or do I really have to send it in to bitmain?

You have more then one connector on the controllerboard for the fan!

Have you tried other fan connector Huh

any loose cables from fan?
jiggle them little if bad connection in contact or cables.

if nothing else perhaps you can buy controllerboard on ebay or somewhere else Huh

good luck!

Try another fan before looking a new board, the control board is kinda spendy unless your under warranty. Buying though would have you hashing sooner if needed.

Yes, I tried the fan2 connector but still the error. Also I tried other Bitmain fans but still the error occurs.
I also flashed the new firmware and resetted the miner completelly with no change.

I am in contact with Bitmain about a replacement but this can take time and the difficulty is rising Cheesy

Yes, connecting RPM signal from fan to the 12V pin kills the board or at least a part of it and fans are no longer recognized
Did you have any luck with Bitmain?
If you have 4 x Z9 mini, you can connect 12 boards to 3 controllers
