They've started charging for shipping to us now. I think they mean the units that have been shipped from China to them have been "recalled". As always I think they say they have stock when quite often they do not.

And now on the website we have:
"As of last week, manufacture has swithed factory and the new batch we received on Monday(9th June) had some issue with misplaced resistors , Manufacture decided to callback this batch, the shipped items are called back and requires some modifications on the miner. we will start shipping around next Tuesday (17th June)
This only affect the batch on 9th June, and A2BOX is manufactured in a different factory therefore not affected. "
Still no email from MinerEU.....
This doesn't sound very promising, modifications on the PCB after manufacturing. Hopefully they will send us miners from another batch. I've got two emails from them about the issue: A2MINI will be dispatched next week due to a manufacture callback . there has been some quality issues that needs to be addressed. we will send another email to A2MINI buyers regarding how we plan to address the delay shipping B.t.w. Did you already use the MX-2 on the blades? |

I don't care much for a batch number. I bought 2 at the same time, and both were different. Both cheap PSU, but the light on the blade is blue on one and green on another. If they both came out of the same batch, I don't want to know what happens in china... And just to scare you (or not): The one with the blue light is still running, the other one is defective  |

Yes I put the MX-2 on, one of them has loads on, and the other I ran out of. Both are cooler and seem fine but are running at 33 and 35 degrees at the moment. But we have had a couple of days of almost 30 degrees here, so that wouldn't help  The blade that has the controller board attached could do with being flipped so the heatsink is in the airflow better, I need to find somewhere to stick the controller though JPS2K5 - Lights on my blades are both green. |

Mine has green LED's on both blades and it is still running.
Only thing I notice is that some of the voltage regulators are much warmer then the others. Must be bad heat transfer.
I will glue some of these small heat sinks for memory chips on top, just have to buy some.

bobsag3 - What PSU did you fit? Did you put it in the case or is it external?
External. Using Corsair HX1050 with 2 CPU 8 pins for power |

My email was replied within ours explaining my A2MINI was not among the 'defective' ones. But I am always very nice in my E-mails |

I'm guessing that whilst they wee "testing" them over the weekend that the faults became evident.
I am also nice in my emails, just waiting for a response......

I wouldn't use that thermal paste if I were you unless you are very careful applying it. It is electrically conductive. I used Artic MX2 (about £10 for 30g), yes more expensive, but it is non-conductive.
Heatsinks look OK though.
I'm convinced though that better airflow across the units is the solution to the heat. Really need to check out reconfiguring the blade positions properly

I will take that into consideration thanks! edit: I haven't taken them apart yet but I can at least put it between the conductive sheet and the heat sink, no risk of shorting anything there. |

These heat sinks looks the same as the ones from Zalman, this is probably where they get them from. With the thermal paste I would be more careful, there is a lot of junk sold out there. Arctic MX-2 is one of the best non electrically conductive pastes you can get, no silicone, so very easy removable as well. I have no experience with AliBaba/AliExpress though. I know this company is founded by a Dutchman. When you order something there, how long does it take on average before you have the stuff on your doorstep? |

I switched from consumer energy to business energy.
Makes a difference of almost €400,- a year when mining with 2x A2Mini.
And the gas is a lot cheaper as well.

I worked out that A2 mini's is costing me somewhere in the region of £600 a year to run. For you to save 400 euros you you must be paying an absolute fortune in electric! |

Yes, here in The Netherlands it is around €0,22 KW/h, mostly tax of course. My calculation is not completely honest because I also have some servers running, but the largest part is from mining. Now I have room to add some more miners, I still have some unused GAW Fury's laying around. I bought these to empty my store credit at GAW. When everything runs smoothly I will add a 3th A2Mini when the price comes down. |

Well I worked out that one A2 Mini is using maximum 400w so for me that is around 10Kwh which in UK costs me about £1.21 a day which is about €1.5. So a year £445 or €550. I do have a 3Kw solar PV system, so some of that power usage will actually be free - if it is not cloudy here anyway.

So electricity cost in The Netherlands is 1.5 times the cost in the UK. Our government is ripping us |
