I have a Class Action Filled against CT, their equipment is sucks and has engineering  flaws that don't allow the miner to maintenance the equipment without void their warranty .

there are no user serviceable parts inside your system which is why they dont want you to open it up.  there's powerful electronics in there... running at high currents  - do the math if you dont believe me - (2100 watts at 0.7 volts = 3000 amps!) - ok, i simplified, and its less watts devoted to the asics and some go to the fans and cooling system, but still, there's some huge amperage in there and you shouldnt open it up.

you cant sue them because they wont let you open it up, as you risk electrocuting yourself.  its not a feeble battery powered device and you shouldnt go poking around in there as it wasnt built to be tinkered with.

sorry you think it sucks, but its a powerful miner and in use by plenty of people (most of whom probably dont think it sucks).  if you're having problems suggest contacting their support team and see if they cant help you.

LOL.. thats just a joke. iff your running 3000A i guess you got a very very expensive welder.. no way a curcuitboard can handle those amounts of amparage.

as i said, i was over simplifying for dramatic effect...  here's a revision with a bit more accuracy.

we all know that the box consumes 2100 at the wall...  but in reality some of that is power supply inefficiency, then some must run the fans and cooling system...    then some will go through their dc/dc conversion circuitry (to drop from 12 volts dc that the power supply provides, down to < 0.7 volts that the asics want)... and its here where (cointerra admitted) is why their power consumption is so high (the dc/dc conversion circuit they used, wasn't efficient enough), which limits the performance of their product and is why they designed it to hit 2 TH/s for the model that comes out shortly...    anyway.. so allowing for inefficient dc/dc conversion, lets assume that the asics get 1600 watts out of the 2100 watts that it consumes at the wall... and lets also assume that the voltage is 0.68v ...   then the actual amperage that the asics are being provided is about 2300 amps (!).   and there's four asics, each one containing four dies...  so 16 dies in total, so each one is being fed almost 150 amps !
