I am running it whit those cables. they are about 2.5mm thick. I know they look ugly but it is working fine , i have been checking them alot, they are not heating up anymore like before. Machine has been working fine, it works fine at Low FAN speeds 10-20 is good else it drops alot in ghz if i cool it down to much so might be some signs that it's not convenient to even run at lower temps?. Ambien temps are 12c and 39c backplate. Asics are running between 70~c and 90~c [H:HW:1592Gh (500),DC-W:865,L:0,A:8,MMtmp:0 TMP:(22/22)=>=>=>(39/39 , 41/41)]

Migh consider to just run the s5.s outside, will put them outside maybe in the week to see how they perfom. The s5 are pulling 1.2kw clocked together they do 2.5ghz~. On the night i am doing 4.2thz~. At morning i am going from 3900 to 4100, i guess the temps might play some roll, need to do some more research. The sun still heats alot . The air Is really cold and getting colder. |

On the night a bit of the "homeMAde" cable is still warm, the other day when 4x pcie were passing trough 1x copper wire , it got RED HOT, and started to burn stuff and melting plastic haha, no dmg too done i got it in time  . Man, please stop using those "homemade" cables! This is not a joke. That's good that you got there in time before fire started, but don't you think that was a sign for you to stop using those cables. You better pay some cash for the good cables then take such risks. I'm not alone here who is telling this to you so you are warned. Hey, it is okey now whit cables. I had made some miss wiring, was passing 300a trough 1 cabler for 2x pcie. i have 4 rails and was using 3. Now each connection got 1x rail and cables are actually not hot anymore and passing 150a by each cable. The cable is HOME wiring , fat Copper Wires so was kinda dissapointed when this happened.' Now it's working fine i will upload pics of the sp20. |

I will put pictures later tonite.
I have sp20 outside, but temps as said before are not so low yet. maybe 0c at night as lowest and around 15c daily.
Fan at 100% still only have the miner on 1650GH/s , asic temps are fine too 2x at 100c and rest 85c.
It is pulling around 1300W from the wall and 2 wires are hot , some plastic melted and burned a week ago, tought was running 2x pcie from 1x wire.
Now each pci-e have it own wire , tought 2x are still running hot but not to a melting point.
snip
I look forward to seeing the pictures! I have been curious what this project will turn into. On the wires are you saying at 0c they are still hot? In 0c the wires should not be hot. What PSU are you using? Also are you using a extension cord? Yeal ill be updating. Just had so much crap outside i need to get everything clean to make some room. sp20 is currently on a server psu. DPS-2000BB , i self made the wires whit home wiring , they are fat Copper cables and should not be so hot actually. On the night a bit of the "homeMAde" cable is still warm, the other day when 4x pcie were passing trough 1x copper wire , it got RED HOT, and started to burn stuff and melting plastic haha, no dmg too done i got it in time . the s5s will sit on a rm1000 together, i am not comfortable to put all the machines on the Server psu and make it fully load. The burnage happened at half load. right now i am configuring and making everything clean , have alot of IT work to do from school so kinda prioritizing but ill keep update as much as i can. Weather is still warm, it got even warmer, but should drop any soon, it should start to snow in some weeks. |

I have not built a box yet. still considering the materials to be used.
I have sp20 outside, but temps as said before are not so low yet. maybe 0c at night as lowest and around 15c daily.

Still waiting for colder temps to start something atleast.
I just can't seem to overclock the sp20 it keeps just adjusting automatic even if the temps are low.
Bringing home some S5 miners, will see tonithgt how they perform outside.

AS long as you keep the air flowing and do not allow water to reach the miner I think you will be fine. This is around February and early march of this year and if I were you I would go for it.
This is the really hard part I forsee. OP talks about a box outside in -20. The miner will heat the inside of the box. I think getting airflow outside without allowing moisture is going to be a really uphill battle. I honestly hope OP does it as I have not seen it done outside in -20. But I sure would start off with a cheap miner nothing nicer then a S3 in that box. I'm afraid moisture will make it the box of death for a miner. The box might get a li ttle heat, but the idea is to have the fulls fully blowing to get the hot air pushed outside. I am running one outside atm, and it's 100% cool inside, but the temps are still warm |

Excatly. So 0.05 CENT are how many dollars?  Well sure, electricity cost might go down. But grid-fee or whatever you call it, will go up! At least here in Norway! Dunno, here in sweden the grid fee and tax is in debate as many complained that it is to high. Electricity cost like 0.0001c and the grid is around 0.02 and taxes about 0.027c . |

my electric bill is 0.05 cents kwh
Do you mean $0.05 kwh? I can't imagine such a low price as 0.05 cents kwh. Even $0.05 kwh is pretty low too. Yeah still quite high for running few mahcines  . Global market has statet that Electricity will keep falling down as the usage keeps raising they need to compete whit the global prices. This is for 2016 the prices would be falling 0.01- 0.02 usd and some more . 0.05$/kwh is very cheap tbh! Prices are gonna go up imo.. ^^ He's picking on your grammar btw, 0.05 cent = 0.00005$, you obviously don't have 0.00005$/kwh prices is not a cent after 0. ?  haha  , But prices will keep falling, i've made some research. Global comsumption is getting higher. It don't mean it will go down to almost free from nowehre, it will take some time , specially were it is costly it might even take longer. Companies always try to get you into contracts because the prices get lowered so if you bind yourself you will be paying 2 - 4 times more than what it should cost at current market price. |

Indeed.
any good investment gotta be a risky investment.
To take advantage of your best chances you gotta make some research, calculation, comparation and alot others factors aswell.
I Count aswell in "real money" as main priority is to pay bills.
Secondary is the profit.
I always count 3x profit = is good.
2x profit = decent aswell.
1x = profit = 0 profit , as you need to pay bills, in this case electricity will consume all your income, making your profit = 0 .
Anyone who do not take risk in a market were the profit can be huge then , that market is not adecuated for that person.

Serious question. Why are people buying these. I just did a quick break even calculation and assuming zero electricity costs, not including the PSU cost, and zero difficulty increases you break even in about 190 days. Obviously those are very favorable assumptions, probably very unrealistic.
Not criticizing the product, just really curious about it, since I mined for a very long time (before finally giving it up last year), and I've bought Ant Miners before, but I now find myself scratching my head. The numbers these days just don't seem to make sense to me.
people whit money like to spend money |

yeah was looking for a s7 actually but for this price i rather buy a new one...
shipping is not 1btc from china. and customs can be avoided.
might be interested for something around 5btc

Condensation can still happen, even if you weather proof it. People have tried these sort of experiments with gaming computers and it never turns out so good.
Well condensation only happens when you have a high humidity ambient. Wich skandinavian is not a humidity friendly place. air is cold and dry. what i know is that KNC have open data centers and there is were i got my idea of as i guess they run this in winter aswell. They close the electric gates if needed but they are never 100% close, always making some airflow whit half open gates atleast. |

What types of damage could the machine takes if they are placed outside in the scandinavian winter. whit roof . no walls ? any overclock pocibilities? Let's say s5 machines sp20s ? this is the idea. The Blow will be outside and the intake will be pulled from downside. PLacing the Miners on the balconi the intake should not bring any moisture from the downside. Weather is pretty dry were i live. The little box will be weather prooff so no water or snow will be getting inside.  I don't know if this is a good idea but I am facing a long cold winter and plan to use my miners as heaters. I live in a small apartment and can get away with spending a lot less on heat while my miners run. I don't know why someone hasn't designed space heaters that are bitcoin miners. What would the cost/benefit be? Well i was going to use them as heaters aswell, but apartments share liquid heating system, so i can not gain any benefit as i can not shut down the heaters to save money it is just not a possible option. I could get the house warmer than usual whit hot fresh air.. I am still checking how SP20 is doing, but im astuck at 1650ghz as highest whit normal temps and fans at 100%. Waiting for colder temps and the new thermal compund. I will defeninitly have s5's inside the house heating the house but if i benefit from colt to overclock i will overlock them outside in the balcony.. ill be updating more soon |

we can offer some of Europe's cheapest power as well - inquiries welcome!
Europe's cheapest power? How much is it? i pay 0.05 cents at sweden, and there are some cheaper options down to south of stockholm. i think cheapest is like 0.01 and maybe lower |

bitcoin THZ has aswell jumped up from 420ph to 480. i guess bit companies already getting this kinda machine This is the reason bitmain has been dumping old tech like crazy. 0.1gwh |

Why not just have a mining box with a small extra fan blowing -20 in and another blowing inside ambient box air out?
If possible have their speed controlled so that the box temperature is at a more suitable temperature.
So just stick your miner/s into the box and regulate the temperature of the box by controlling the amount of air coming in and out of that box.
Of course be careful that your box temperature does not fluctuate up and down much. Fast temperature changes to electrical devices is death.
The idea is something like this. But the fans of the machines are to strong to keep it sealed. So exhaust will be completly open and intake aswell whit a fan pulling cold air inside from the bottom. Fans form machines will be pushing out.
My IT techer even told me that why not put the machines inside Oil cooling and cool down the oil whit the winter cold.Might even be a clever solution, oil will protect from outside and will be more seleaded swell. None of these machines you have mentioned were meant for immersion cooling. Be careful as it sounds like your teacher is giving advice he is not familiar with. You might have to find special fans to handle this. I don't think most of the fan's will last. I think get brittle and break. But that is a guess no one has tried what your doing that I know of. Yeah my teacher do not know anything about asics. tought it's cpus . The idea of this is to not have fans but normal water cooling system like aquarium. I don't think i will try out this tought it's just to much work to be done. I've placed the machine outside, tought it still warm. 18 °C / 79,69 °C temps are a bit high. 2 chips are running at 120c and rest aboud 100c. Still waiting for the new thermal paste to get home, hopefully it will bring down the temps. Outside temps are about 10c still nights around -3c. |
