GPUS with 3 year warranties have a place in a low power operation. My solar array deal with buysolar is 'free' power So the gpus would earn for as long as they last.
Does an fpga have a 36 month warranty?
not for mining use, its 30 days (or 90?) they reduced it from their standard warranty period. i believe they said you can buy extended warranties however. thier main concern was DIYers ignoring ESM precautions and abuse due to ignoring proper installation (heat, power quality, improper installation etc).
still these are industrial units with a proven reliability record, in wide use in industry (so bittmex says, and i have no reason to doubt them atm) , not bitmain trash. while i am a bit disappointing, i still would buy.
their monitoring software monitors a lot of sensors to keep it in the safe zone, which is the main reliability point imo.
