Hi everyone,

I just received an S9 miner and operated it - no glitch - for about a week.

Now the S9 reports sporadically fan failures and then looses connections.  The chip temperature stays close to 100F and the fans seem to still be running (the machine continues to be its usual noisy).  I haven't seen any thing else out of the ordinary.  

My questions:

Any suggestions to where to get one? or how to find a generic fan? (It seems bitmain S9 fans are sold out.)

The error reported in the log is: "Fatal error: fan lost!"

The fan reports 0 RPMs on the miner status page.  Fan 1 is failing - is that the intake?  Can I flip the fans the test them?
