When ambient is at an acceptable temperature, you just need ventilation. It doesn't matter how much heat you put into the air if you can simply substitute that air with ambient temp air.
You think if even is +40C? Yep. It doesn't matter how fast you wee into a cup, if I keep replacing your cup with an empty cup, you'll never fill it. not quite a correct analogy. Ventilation does not prevent turbulence. Air can be travel inefficiently that hot air got suck back into the miner . You need to build a ducting system right at the rack. Thats the only way to control direction of air. Remember folks, you need ventilation and air direction control to be effective. You don't if you have floor to ceiling double ended ventilation. Ie a door on one side and a door on the other.... I have my miners in my garage and this will be the first hot weekend of the summer. I'm hoping that by opening my garage door a few times a day I can recycle the air. Its north facing and thats where the cool wind comes from. If that doesnt work I have a 12000 BTC portable AC unit ready to go. Would rather not use it though. That portable AC unit won't do anything in your garage. Once your garage's ambient temperature starts to increase well into the 80's and lower 90's there isn't much you can do. And since most garage's aren't insulated (why would they be) they are hard to cool and hard to keep warm. They aren't designed to be. Notice no videos with these powered on? There's really no where you can put one in any house and not hear it. Its an attached double garage that is insulated since im in canada. I think it will work I'll place it right near the miners I take and ezhaust through the wall to the outside. Right now im running 21 S1's and I cant hear them inside. 1 SP10 cant make that much difference. Im already using loud server psu for some of my ants. damn for a sec i thought you said 21 SP10s!!! I wanted to know what kind of garage.... hehehe until i realised .... What is your total power consumption right now? |

However if you have multiple SP10s.... you will have a problem. |

No, that is super super max. Click on each of the presets then advanced and take a look at what each of those modes tries to set for an idea of what is going on.
that's "super super max." is what I am trying to point out. SP's document states "Default = 790mv" which I believe is incorrect. It should read Default = 683mv. Please correct me if I am wrong  Cheers, QG This is the maximal voltage that the miner is *allowed* to reach in its dynamic scaling. Setting to 790mv is practically unlimited, it will stop somewhere between 670 and 710. depending on the temperature and the corner of the ASICs. If you want to make the miner more efficient (but less productive) you can set it to 660, 640 or even 600. I would not go under 580mv - some ASICs start to fail unless if you got a fast corner (but we were not lucky with our ASIC corners lately - only first batch can handle 550mv). So far best configuration for first batch (April) is start-voltage:660, max-voltage:790, for second batch (early May) start-voltage:680, max-voltage:790. I am working on making the scaling efficient on our latest batch (late May), hope to have results after the weekend. What causes the variation between batches? Normal ASIC production variations. First batch was typical corner (middle of the bell shape curve) Second and third batches were slow corner All the miners will be within the 1.4 THs +- 10% published spec, hopefully on the plus side You didnt answer my previous questions, how is the exhaust air temperature measured? where is the sensor located and what type of sensor is it? (possible the name and model ) I assume the front/back temp are intake/exhaust air temp. I have very good reasons to ask this. |

Ie a door on one side and a door on the other.... Right, you expect the room layout to work with you. Stop making empty suggestion like this pls. Build a ducting system from the rack to wherever the vent is. Or, or, or, maybe this... don't put a mining farm in a room ill equipped for mining. I choose my flats almost solely based on their suitability to mining and cooling. Proper Planning Prevents Piss Poor Performance! So why dont you suggest that? Ppl dont usually have luxury to choose their mining room. Not to mention residential house's rooms arent built to take 1+ kw of constant heat. |

Its north facing and thats where the cool wind comes from. If that doesnt work I have a 12000 BTC portable AC unit ready to go. Would rather not use it though. Exactly! For the vast majority of the year I cool my miners passively, with 0W. In the summer I simply add a 60W fan to help aid the ventilation to ambient. Its 40x more efficient than using AC. I hope noone can just blindly follow your suggestion. There is a word called BTU. You dont just add 60w fan to cool.... you-dont-know how many kW. Anyone looking to cool a mining room, needs to do proper calculation of the amount of air volume you need to move. With the dimension of the vent you have, you can calculate the air velocity required for that volume, then you can pick a fan. Fan can use from 50w to 1000w. |

Me and my dad are on the fence about this. It would be just one SP10 for each of us. We are already running a KNC Jupiter and would love to keep both miners in the same room, but at 110V the AMPS get all the way up to 10-11amps. That's basically an entire circuit we need to find that isn't being used by anything or get to the home depot and run our own lines into the room.
Does the SP10 run better or more efficient if it is plugged into a 220V line than a 110V line? Does it run better?
ANY electrical device runs more efficient at higher voltage. With the SP10, the FW will allow higher hashrate with 220v as the FCC limit the draw on 110v line, so FW has to restrict the power usage thus limiting the hashrate. |

SP-tech, can you tell me how you measure the exhaust temp. Is it right by the fans?
My air duct blows just abit warm air but the SP1s report at 72c.
Also can you tell me which sensor you used? I would like to see the tolerance level.

Tzortz what is the temp in your room?
Is it AC´d?
No AC. The temp in my room is 20-25C. I can have all the doors open, and makes a nice flow. Inlet in the SP10 says 35C. Wait for a couple of months and tell me again your temperatures...

In my impression ,Chinese government doesn’t plan to ban virtual currency completely . This joker keep saying the same shit. He is either lying or denial that his business plan doesnt work out ( duh! he thought he can grow financial services without deep connections in China? ) |

I would have thought a $10 DigitalOcean VPS would do it. If someone would like to fund this for $10 a month, then you have a node. =) Any money sent here will be used to fund full nodes. (If I don't get enough I'll return funds to sender.) BTC: 1PTToEChNHYmtYpk1D4siscJdSwV1oYCNX Fck off.... $19/ year is what the topic says. I hope no1 "donates" to you. |

Never been a fan of TBF, and I don't think they have done anything enough meaningful for bitcoin But if the foundation members could jointly provide some fiat reserve as backing for bitcoin, to ensure its price stability, I might consider join  The dumbest thing i have heard this year.... i hope nothing can top this. This forum never cease to amaze me tho. |

I find it interesting that always "newbies" ....somehow "found" new miner manufacture sites,
I'm sure if you put bitcoin miner in google, this site wouldnt have come up.... hmm.... make you wonder.....
are wolves out there hiding in sheep skins?
