I bought a miner from these guys in Nov of 2013, a year later this is what they JUST sent me. They are still collecting peoples money at this site http://amtminers.com/ We all have made complaints to the FTC, FBI and any other agency that would listen. They also send me this miner with "NO POWER SUPPLY", it was supposed to be an AMT miner, but what they send me was a "no name" knockoff. Believer it or not, many of us paid them $6,000 for this, and at the time of delivery they were selling them $899. It is a VERY VERY high probability these guys are going away to jail for a VERY VERY long time. The miner also says it hashes at 1.28 Th/s in the mining interface, but the reality is its hashing at 900Gh/s on BTC Guild.

You were clearly see these were used and very dirty fans that squeak as well. They are three COMPLETELY different fans. I would go as far to say, these fans are so dirty they must have been used in something other than a computer. The miner was also filthy with black soot all over it (as you can see), It's pretty scary. The green fan you see in this photo, it just BARELY spins, its almost dead. Useless... The green fan is so slow because the "RPM Sense" white wire has been cut and that is why it doesn't work properly.... I guess I really got the naughty list special miner...

3 different brand fans, very dirty and used looking. The green one hardly pushes air because of the wire that was cut.

White wire cut right in the middle of the run. wires cut and then put heat shrink on them. Beyond a hack job...

mis-matched connectors, showing 3 pin and 4 pin. Different wiring, but were all in the same type of 4 pin socket. Surely not wired correctly. This is a hack job.

what the web interface says its hashing at (temps always this high on everyone' miner) also miner ALWAYS says 1.27 or 1.28, no matter what. Also the 256G on each card also doesn't move. It's obviously a fraud.

the reality of what it hashes at: (often drops to 900Gh/s)

Seems like they've run the miner for as long as possible to get their money out of it before shipping - seems to be a common complaint with some of the companies who manufacture mining kit. Looks like a friday afternoon job to me.

have you tried fitting 3 reasonably high CFM fans in replacement of those dodgy 3? I wonder if theyre not moving enough air and the miners are being downclocked due to heat - also have you tried blowing through the system with an air compressor to shift any build up of dust?
