I thought there was a video some where from BA showing/saying to break off those capacitors on that board. I could be wrong. I'll see if I can find it.
Those were the green caps that were at fault. This pics do not show them and it looks like it's a newer revision. Wondering if that hashboard is faulty, in which case it can be pulled. i've got a better idea. don't plug it in. |

So I recently purchased some X3 Units, and 2/4 boxes burnt down. One was burnt to complete rubbish (picture below), worst part was the blade was burnt from one end to the other so the machine stayed on causing quiet the smoke and an awful smell of burnt plastic, spoiled eggs, and burnt electronics. LUCKILY I was home..I was able to unplug em and throw the unit outside in my shed.  As for my second unit, it kept going on and off and hashing extremely low. The smell of burnt plastic kept coming and going. Opened it up and saw it begging to blacken/char on the metal of the blade; needless to say I threw it outside as well as the major fire hazard wasn't worth the cost of my home and my other mining gear or better yet my life.  Neither of the units were at default frequency; in fact all my units were under clocked and on its own dedicated 20 amp breaker. So yeah..not sure I'll be using Black Arrow products anymore. I tuned into this thread again to see how the BA fire boxes were going... seems there is no shortage of smoke or fire and that these units are probably the worst miners ever made. Lucky that you were home and awake when the units caught fire, could have been a terrible story otherwise.  |

The worst they can do is melt, which is what is show in the pictures above. |

oh, that's OK then your miners MELT. Just to be clear. I am not saying it is ok that they melt. It is a very serious problem and frankly unacceptable. However having the actual unit catch fire and light other things on fire is not possible. |

However having the actual unit catch fire and light other things on fire is not possible. and if it ever does, what will be your statement then? i'm unsure if your statement above shows ignorance, lack of knowledge, or simple criminal negligence. You know who i fear for? it's those people who have received units and have listed them on ebay, knowing full well that by doing so, they are endangering the lives of those who buy them. Just as Black Arrow have endangered the lives of those who purchased from them in the first place. if there is propensity for the units' parts to melt, then there is also propensity for them to set on fire. the pictures already posted on this thread show scorch marks, and not melted components. Scorch marks are an after effect of overheating, as are flames. I will go so far to say that your ignorance is deceiving people into thinking that there is no way these units will ever produce a flame when they overheat. I will also go so far to say, that the propensity to catch fire, is there. you cannot spin it any other way - The overheating of components HAS the propensity to catch fire. It's as simple as that. |

The guy who originally had the fire was due to the blown caps. They removed the caps from shipping units. The current reason the units burn out is apparently due to a bad mosfet that causes a short which then melts the connector between the hash board and the backplane. The components here aren't "burning".
In truth, any electronic component can catch on fire. Take some lighter fluid and pour it into the case and toss a match in there. Flames!
Ultimately what David was saying is that the internals do not create flames. They do however release toxic fumes that will cause you to grow a third eye on the palm of your hand. Which is fun at parties...

An electric heater cannot catch fire. However, it can START one. Same goes for anything else if it gets hot enough, including a badly designed miner.

@bobsag3 Dear Matt, you have been answering us well, thank you! But since the 29th of August we believe you have been very busy, but we need you to answer our emails!
Thank you!
I've been waiting for a promised refund from Minersource for more then 6 months now. They gladly take your money and ignore the laws of their own country. |

What complete tools these people are. No, wait - tools can be useful. They are mites on a flea on a pimple on an abscess on a baboon's ass.
Wear that negative rating by BA as a badge of honor. It's not like anyone in their right mind would have them in their trusted ratings network.
Great thread btw - I wish it had been around when I ordered my 3 X-1s from BA in November 2013 (and still haven't received, of course - not that I want them at this point).
I would have posted my thanks directly there (to bump the thread, too), but it's locked.

That is a good indication that what I published really affects who is behind blackarrow forum user. Otherwise, why would anyone be so concerned with a buried thread published 106 days ago when there are more important matters to solve? I mean, while there are countless customers issues to be addressed, leave negative feedback for an inactive forum user is top priority!
Sent you a positive trust rating to help counter balance the BA crap. |
