EDIT:And this is now sold to Zerinoff.  Thread is now closed and locked. Hello guys and gals,
I'm looking to sell three pieces Innosilicon A4+ LTCMaster 620Mh/s miners.
These are low noise level miners.
I have replaced the original cooling fans with Enermax D.F. Storm fans which are modified
to run at full speed 24/7 (3500 rpm).
This provides a great balance of low noise level and effective cooling for the miner.
I will of course also include the original Delta Electronics fans
and I can install those original fans prior to shipping if the buyer wants so.
Changing those fans did not damage any warranty seals.
The warranty for these machines is 180 days and it is valid until June 13, 2018.
Price for all three units: 0.6 BTC (including shipping)
Location: Finland (EU area)
No PSUs are included.
No cables are included.
Picture showing these three units: https://i.imgur.com/rx14tsg.jpg
Please hit me with a pm, if you are interested.
Escrow accepted,
the escrow fee is at buyer's expense.

So I have a dead hashboard. I did the logical thing. I dismantled the E9+ and switched boards, switched power connectors and data cables to the board.
Still the same, the conclusion is a dead board.
I took out the dead one, and moved the remaining 2 boards into this position - board 1 -->empty space --> board 2.
And I remove the intake fan and just run the miner with the output fan. To my pleasure, its is now running at 6plus TH/s and alot quieter. Temp of the two working boards is constantly at about 65 degrees C.
Now I'm thinking to get 2 lower RPM fans for both push and pull, and replace the current miner's fan. Probably like 1000-3000 RPM, maybe?
Any recommendation pls? Need the model number preferably.
I would not recommend it, but if you really want to try to go that road, I would recommend getting two of these: Enermax D.F. Storm (max. 3500rpm - 155CFM) |

@yxtI think it should be quite obvious that you don't have to tear it down completely if you only need to change a fan.  But your suggestion is good, I will change the order to -> 2. Troubleshooting - 3. Tear down. EDIT: ^ This has now been done and the guide is updated (April 2, 2018).Any other ideas?

Hi, I sent you a pm. |

Ok.
But this is the first time I see a video showing the F3 miner.
I have not seen this video being available until today.

Is there an expiry to the coupon usage? Never brought from Bitmain and with the current situation, sensibly shouldn't. I would not want to waste away any of your kind gesture and deny others if they have to be used soon.
These coupons have following validity time: Validity Time
To 2018-06-01 18:10:00 |

Nice, thanks for joining in. |

EDIT: I have closed and locked this thread in April 14. My coupons are now all gone.
Happy easter and happy mining for everyone.
These gentlemen who have posted in this thread might still have some 100USD coupons left for give away:philipma1957generaltBenRickert
EDIT: Added BenRickert to the list, sorry that I forgot you..Hello guys and gals,
I decided that I'm giving my -$100 USD Bitmain coupons away for free.
Max. five coupons for one person.At the moment I have 17 coupons left.
I have 12 coupons left.
I have 7 coupons left.
I have 2 coupons left.My coupons are now all gone.The most ideal situation for me would be giving these coupons to guys who are new and starting their mining operation.
PM me if you need some.
Remember to mention how many you need and your Bitmain.com username.

Just one thing that confuses me in this, is that why both parties (Halong and Inno) do not want to confirm anything about this OEM or other partnership deal?
Revealing the fact that the control board design is very much the same got me kicked out from the Dragonmint telegram chat room.
What are their reasons on this?

Comparing pc parts with asic hardware is not that simple.
When you design your ASIC hardware, you design the whole set all the way from control board, hash boards, chips to be custom made and compatible with each other.
But it is possible that Halong and Inno has had some partnership deal in which Halong has got an access to Inno designs and have that way been able to implement the Inno control board in the Dragonmint unit.

I deleted my previous post, since I need do to fix what I said. It used to max. 115C according to Bitmain, but now the S9 user guide mentions that 125C is the absolute max. Ref. page 12 in the S9 manual. https://file.bitmain.com/shop-bitmain/download/AntMiner%20S9%20Installation%20Guide.pdfNote:
The S9 miner with automatic frequency adjustment firmware will stop running when the
Temp (Chips) reach to 125-135°C, there will be a error message “Fatal Error: Temperature is too high!”
shown in the bottom of kernel log page. |

You asked for my comments and I gave them. I don't know what kind of patens Bitmain has, it is hard to say if there will be any lawsuits. I do know that Bitmain has had or is currently having a lawsuit with WhatsMiner company. |
