I purchased a ASIC Block Erupter Cube from this company for $1800 about a month ago and the cube is defective. I has not worked since the day I got it. I have 3 other cubes that have been working great that had been purchased from a different company. I have sent multiple support emails through their web site trying to get the issue taken care of and they do not respond back. Has anyone else had any issue with them? Also does anyone know where I can get a replacement main board for the cube. The Cube will run from anywhere from 1min - 45 min then one of the two power ports turns off. I have tried multiple power supplies with no change. I have looked around on the forums and tried everything other then adding a bigger capacitor inline with the power plug, I have not done that because I am not sure what exactly they mean and I can not find any photos of it done.

Hi, Id be willing to take a screwdriver to it, if its running but failing it could be a hotspot / dry joint on the board somewhere.

Open it up, test one board at a time, push lots of air at it and watch the temps.

I have tried everything. I actually found the problem, there is some issue you with the fan. I hooked up a small fan and it turns on and runs fine. So I went and got a brand new replacement fan and the problem is back. I have to hook the small fan up and leave it out of the erupter cube case, I installed the new fan and also ran the power wire out of the side of the case to the power supply. so far so good the block has been running for over 10 hours now. I have also found out that not only do android phones cause an issue with the Cubes but so do the google chrome books. If I have my cell phone or the chrome book connected to the wifi the cubes wont hash more then 1-2 GH if that.
