Re: Antminer S9 Fatal Error: some Fan lost or Fan speed low! (on ghost? fan)
Glad you could fix it. Sometimes when the S9 has a faulty fan you will see two speed outputs from it.
Side note, if you ever see the speed 30600 you have a faulty fan; the tachometer has crossed with positive voltage, giving you the max speed reading 255 * 120 = 30600. The newer firmwares are set to stop mining when this happens.

thanks Tim, that is interesting! I have actually been seeing 30600 RPMs for about couple of month on one of the fans (must have been the same one) but it continued on mining and temps were fine, so I didn't research it
This is good to know!
