I received my X-1 today. And now the fan doesn't spin up.  Angry

After several months of waiting the only thing I can do with it is playing some Android games.  Undecided

And I thought it can't get worse...

I saw on their forum that sometimes the fan connectors are installed backward.  try flipping it.


Tried it already. But it didn't work. The fan is definitely broken. I connected a CPU fan to the connector on the X-1 and it spinned up. Then I connected the X-1 fan (some Cooler Master 200mm fan) to a motherboard as chassis fan and nothing happened.

You should complain! The unit is obviously faulty!

I have opened a ticket and told them to send me a new fan. I'm currently waiting for a response.

Now you can add that BA didn't had enough time to make proper video, add that proper video is improper and cry more about everything else in the world.

But they had the time to design a new 14nm chip?

This time they're really quick. Not even 12 hours after opening the ticket I got a tracking number for a replacement fan.

I think the only way I will get anything back is by selling it on ebay. Even then it will be a loss. As energy costs are quite high here in Germany it will produce even more losses when switching it on.

Did you try to downclock it? It can work at 0.5w GH. at 40 GH/S total Consumption about 25w, if you remove fan and LCD as well place smaller fan like 20 x 20 mm it will be even less. Best i got was 19 W per 40 GH, and it worked without fan. Just don't forget that you can ruin PSU without any cooling applied.

40GH earns you $2.18 per week at the current difficulty. You pay just over half of that in electricity at current German prices. So not making a loss, correct, but no chance to break even either. A couple more difficulty increases will kill even that meager profit margin.

Thanks to BA's eternal delays, not a single customer will ever have a chance at breaking even on their purchase price, unless the price of BTC skyrockets again.

Half is better than 0 if your electricity is expensive? Well it's up to you anyway if you want to do that or not.

I couldn't make any tests because of the broken fan. I'm waiting till I get the replacement one. But I had planned to undervolt and downclock. I have read the voltage adjustment thread on ecointalk.

It would not have made me rich, but if BA had delivered back in February I could have made more than 600$ (~1.3BTC) (w/o electricity costs) at current prices.

Yes, it is. But I'm never going to break even earning $1 a week.

WTF is your point, anyway? Are you a BA shill, little newbie?

Oh please, I have hawked AsicMiner and Bitmaintech in the last 2 hours on this thread.  Do you honestly believe they are paying me to go after you?  Why would they?  They ship quality products from in stock, and guess what, not a single of their units have ever exploded.  Guess those high quality parts are pretty easy to come by.


Ok, I won't delete your post again and reply you instead.

AM sells only chips and they are lower quality than ours.

Would you please now go away?  You are not our customer, you have no business here.

Your further messages will be deleted.

Shysters?  Pre-orders do not equal 0% financing.  Shysters.

Waiting for a tracking number from BA. Payed 12/08/13 and have gotten nothing but the same old excuses.
