Fatal Error: some Fan lost or Fan speed low!

The fan plugged into the outermost socket (the left one if looking from the front) on the controller board is dead, and you must replace it before the miner will hash again.

Yes, there are software fixes like recompiling the firmware, but running the S9 with one fan is a recipe for disaster. Fans are cheap, pick up a few in bulk.
