I did get lucky mine is still working great.   Sadly power company did a upgrade and I lost electricity during it, turns out they like to work on wires that are not live .  But if was not for that I would have hit 30 day mark of working and not having to change anything.  I think 24 day's was highest I got on getting pictures of it.

And Ferol is right about fixing these.   If you do anything even fan mod you kill your warranty now day's.  So make sure you get bitmains permission before trying to fix it.
