How common is it for these ASIC loops to drop off or need to be disabled? Essentially that is reducing your mining power.... Expected lifespan? Do we even know?
I've got one of the first SP10's ever made and no ASIC dropouts. ditto. still the world's best miner Ditto as well ... but I don't think this problem ever showed on the SP10s, it's a SP30/31 thing and maybe now the SP20. (Stand to be corrected if I'm wrong). SP10 ... solid as a rock! SP30 has been good so far in my experience as well, SP20 well considering the abuse I am subjecting it to its not doing too bad either. 5+ hours on 2.5.12 with no errors. |

Hello Everybody,
So I'm quite taken aback by the loud fan noise generated by the stock SP20 fans, was all along thinking it would be comparable in terms of noise to the S3 series.
Has anybody managed to replace their SP20 fan to something which solves the noise problem? Any known models/plugs/settings to take note of? I reallllllly need to get the fan issue solved if not the miner is just going to be switched off. Looks like I have to reassess my definition of "home mining".
Cheers
Really do we need a new thread for this? https://bitcointalk.org/index.php?topic=521520.msg9469805;topicseen#msg9469805Its a 200+CFM 60+ db fan on a non-standard power connector. Good news is that the unit doesn't care if there is a fan plugged into the header. I've currently got two Coolermaster Jetflo 100CFM fans powered from the PSU, one replacing the internal fan and one on the outside pushing air in at the back. Not-so good news is thats not enough airflow to keep the unit performing at spec, sweet spot seems to be just under 1.4TH Temp Front / Back T,B 33 °C / 86,87 °C But its now normal miner sound levels  Going to try a 150CFM fan, I guess you could solder the custom connector onto the fan wires if you wanted a stock look |

Unfortunately not.
Fan remains at 100% throughout.
G & Y leds remain unlit.
Ether/LAN leds alternate between solid, blinking and off
By SW upgrade i assume you mean SD Recoveries?
If im mistaken, please advise at your earliest convenience.
Before beginning the RMA process, would it be possible to have an SP20 exclusive SD image to try?
EDIT - after about 8 IDENTICAL 'recoveries' it has shown up again as SP30 with SP30 fw and SP30UI
After more skype-ing and correct understanding it was FW Upgrades x 2 PLUS reboot that eventually got it back in the ring.
Sorted! (1534 GH/s - fan at 90, max power at 285)
(now back to day 9 of Data Recovery...)
Glad you got it sorted edgar. I'm still on 2.5.7 with no issues, running two 100CFM fans so noise is solved, but heat is my problem, I've got temps of 35 °C / 87,89 °C with max power set at 250W and a solid 1355 GH/s Need to get some cool air into the room, time for some building modifications methinks. |

Did anybody received Miner of any kind (except of lifeforcepools )? (Titan, Excalibur) Please PM me..thx.
No and stop bumping this scammers threads. |

If you are an expert, please send me your CV and we can talk about a job offer for you over here to Thailand to help me a perfect cooling bitcoin mining.
FYI. This cabinet doesn't use refrigeration, it use precision cooling data center with airflow optimization front to back.
I've highlighted your problem right there, you need to be in or close to the Arctic circle or Antarctic circle to make use of low ambient temperatures, then all you need is high airflow, and in the summer when the ambient rises a bit you can use evaporative coolers if you need extra. You're just in the wrong place thats all, your trying to find a solution to a problem that doesn't exist where bitcoin mining farms are best located. |

Does anyone else see problem with 2.5.7?
Not noticed a problem with mine on 2.5.7. |

Some SP20 Pr0n
Pr0n means "naked" .. that's fully dressed :p Nekkid SP20! Top off!  Money Shot!  Hashing Boards!    Controller Board!  Video: Fan @ 80% |

start counting!
approx 8*3*3*6 (plus another 8*3) = ~450-460 units. This is one building, apparently 3 were in the compound Has there been any investigation as to the cause? I know the owners are keen to put it behind them and move on. Personally I don't see it being caused by a miner. But then the finished pictures paint a much more professional setup than it looked in earlier pics, or the aftermath pics. What I haven't seen is any pictures of the other side of the miners before the fire, the power side of the racks. That is what most people seem to be interested to see, it does seem a bit strange that there isn't anything showing that part of the setup, because for a minimal cost mine the finished photos like a damn site better finished than most. Yes they didn't have many things that a professional datacentre should have, but then thats not what its about, you can't achieve ROI if you build or hire a professional datacentre for mining anymore. I'd still like to see the business end of the racks and detail of how they were wired up, but I suspect that won't happen. |

Gone from 1.3x to 1.5x 1.665TH and climbing now, back temperatures gone from 37 to 67°C 77°C!
Keep your room cozy and warm in the winter ... I am going to have to do something about the fan though, this thing is loud! Louder than all my other miners combined. If I can't do anything about it I'll have to sell it I think  This is the fan used in the SP20.. beast of a thing!  Damn, fan uses a 4pin PWM Graphics card type header. Going to have to get one of these if I want to try other fan types:  PWM Fan Adapter for VGA Cooler FanDon't buy this adapter its a different fitting on the SP20 Good news is that it runs without anything plugged into the header so I'm testing another solution |

Just give the account details to the buyer and start a new account.

Im surprised its in Thailand. They dont have good electrical rate at all.
My guess would be laundering money for triangle drug lords ( Myanmar, Cambodia and Thailand).
My guess the reason for the fire is in the word "Thailand". God knows what they think is adequate electrical code. Looked like millions of dollars of SP30s were hosted in a chicken shack. I hate to say it, but I'm not shocked at the outcome. To be fair, most of the farms in China aren't much better. Unfortunately this may not be the last we hear of this sort of thing happening I fear. Some would feel a certain Dat0rhall in Iceland would have been a more poeticly just location... But I somehow think that the arctic was a better choice than the equator and that they are more scrupulous about their wiring. |

DC's will be thinking twice before allowing people to host this gear now, at least at unrealistic densities. Imports may receive greater scrutiny.
It was a cowboy DC though, no reputable DC would rack them at those density levels. They were asking for trouble. Plus the entire thing most probably including the wiring was done all on the cheap to maximise profitability. They just took it too far in the density stakes and overloaded their wiring it looks like. |

Holy sh*t!! I shed a tear for them.  Better not pushing your SP20 with some random PSU. Have fire extinguisher near by and get a Nest fire detector (or any smart detector) No need to be a stupid troll about it, its obviously a hastily setup on the cheap farm with dodgy wiring. Once an electrical fire starts like that in that sort of setup there is no stopping it. Could have been caused by any number of reasons. And has zero to do with the SP20 seeing as all of those machines are SP30  Dumbfck i know full well they're SP30. Its not uncommon for the fire to start from PSU. It happened to several ppl back in GPU days. What a fcking noob So why troll about the SP20? And as for the noob dig.. you sound like a 6 year old girl if thats your comeback LOL |

If I can't do anything about it I'll have to sell it I think What is the fan settings? Anything from 60% up is louder than a KnC Jupiter or Dragon, louder even than a 6 GPU X11 rig. I'm away from the unit at the moment but I'll do some sound measurements when I get a chance. I thought it would be quiet, I'd hate to have one in the house. I'm want to make too big a deal of it because I should have known really judging by the noise of the SP10 and SP30, I just would have thought knowing that this was designed as a home miner you would have designed it with two quieter fans in a push/pull setup rather than one Delta type 120x38mm Fan. Its also not wind noise, its the mechanical noise of the fan itself. I've got a lot of fans here I'll find something that works. |
