It is extremely high noise level! We have a new situation. Bitmaintech rapidly changing and sells s5 . We have a new deal to s5 . Only 352 USD ( 1.323 BTC) . Hashnest also got a new s5 delivery . It looks like the S5 will get a good deal on the market. |

The USD352 is second hand unit from local China. I have very bad experience with second hand unit.
Before you buy, you must think the environment of this unit, mainly the china warehouse is full with dust and they running with water cooling systems, which will make the screw get rusty....

I did the math on the thermal design of this unit. I think it should be fine, and basically equivalent to an Antminer S5. In our facility, the new S5s (with heatsinks on both sides of the board) have ASIC temperatures of about 42-50°C when using 20°C intake air. This means that the temperature difference between the ASIC silicon and the intake is about 25°C. Given that the power usage is about 10 W, this makes the thermal resistance to air about 2.5°C/W. The delta-T is about 5°C, which makes the back ASICs about 5°C hotter than the front. This S5+ reduces the power per ASIC to 8 W. This means that the ASICs at the front of the machine should be about 20°C hotter than the intake air at the front, or 5°C cooler than the S5. The fan to power ratio for the S5+ is about half the S5s, making the delta-T about 10°C, or 5°C hotter than the S5. Add those two things together, and the rear ASICs should be pretty much the same temperature in the S5 as in the S5+. If anyone wants to buy one or more of these, Toomim Bros can host them. http://toom.im. (I hope someone sends us one. I want to see how well they work.) |

They did the right thing. If you want to put this amount of equipment on the market, the price must be lower. The units may be dusty that is the fact but i have not heard about rusty screws or other components. This testifies to the high humidity in the mine. |

Those must have been running even before the S5 was released! They have an S3 control board and not the latterday BBB ...... . I got my first S5 in the very first batch and it had a BBB! WOW! And to think you paid more for this than anyone did for a brand new one must leave you feeling sick. |

I thought I was seeing things! Thanks for clearing that up .... How much did you pay for the S3++ from bitmain then (if you do not mind)? To clean that up, get some surgical spirit (Methyl Salicylate) and a fine bristle paint brush ... and it'll be as good as new! I use that spirit because its very cheap from a pharmacy and works a treat even for removing thermal paste, but if you know of better and cheaper .... |

No evidence of rust, and no dust, on the pair of used S5s I got early this week. I'll also point out BitMain is giving a warrentte on these, think it's the SAME they were giving on new units. I DO wish they'd dropped the price a week sooner. 8-( |
I'm no longer legendary just in my own mind!

Good thing the warranty got extended to 30 days instead of the initial 15days, otherwise i would barely have any time to test it. |

Your photos fail to show how it is powered making it less likely it is real. You also do not show a working unit.
lol i just giggled a bit when I saw this...Id love to hear your logic on how this is "fake" when you were promoting the cloudthink.io scam and all they had was a horribly done "graphic" images of a fake miner. |

So please be accurate. --------------------------------------------------------------------------------------- and the op is asking 3299 usd for this thread's item while it now lists for 2750 on bitmaintech chinese site So while the item has turned out to be real this seller wants far too much for it. |

I have send back all the unworking hashboard and control board to Mr Gao, but, long time no news no feedback from them. Im have not much hoping for that. |
