Hey guys!

Yesterday I got my first antminer s9 from ebay and it's been a nightmare lol.
Not going into further detail I guess I just get straight to the point.


I turned it on - one or two boards were at temp 15 at 0 hashrate.
Turned it off - put cable out & in - working properly for 2 hrs

Next morning same problem. Some boards didnt show and i had it working for a short period of time.
I noticed the intake fan stopped working and I'm getting a fatal fan error (get fan speed 5160 loop and then fatal error // before that "bmminer not found"

Today i was trying with a replacement fan from a friend and got the same Issue - intake fan isnt working.
then we tried switching pins from intake and exhaust fan - still intake fan not working? this is where im really lost and it doesnt make too much sense to me.

How can it be, that after replacing the fan with a new one (ruling out that it's an issue with the fan.. or we got really unlucky and had 2 broken fans I guess?!)
AND then switching the input from PCB to broken fan with the working fan pcb connection that it's still the exhaust fan which is not working?

I'm really confused!

Anyone any idea?

Oh, and further then that im trying to get the latest firmware from https://shop.bitmain.com/support.htm?pid=00720161126080548570Q2tDBXAH065D but I cant download it? It seems like the server isnt working. Is there any way to get older firmware maybe? (or at least the newest one .. I heard the Nov 17 Firmware is a little buggy)

Thanks guys. Would really appreciate any information.

edit: did update (again) to newest firmware. still same problem
