Happy for you to do that if you like.
If you fill out the survey you get the results as well in pretty graphs.

To back up my claim that I've been happy in the past with Mr Lee's supply and hosting of Dragon A1 miners, I have traded in my 3 Dragons for 5 S5's hosted with him.
He was flexible, allowing me to part pay with Paypal and part with BTC
Provide a fast turn around, miners were up before I finished sending the second half of my payment!
Miners are running at spec and on pool.
Comments:
Have some pool changes I need doing, and am concerned that in this day of needing to change pools manually fairly quickly to catch things like Rental windfalls etc, response times to pool change requests by email may not be ideal. I'd like to be able to do the pool changes myself.
Remote access could be a good addition, I know it wasn't successful in the past and I opted for a set and forget viewpoint, but I'd like to see it explored further.
All in all, very pleased with the experience and happy to continue as a customer.

You don't need water cooling to have quiet. You just need to stop designing for maximum density. Spread the chips out and use nice quiet slow big fans. That's really all water cooling is.
If the SP20 was twice as large (same number of chips, without putting 2 chips in line of the airflow) it would run much better and quieter with 2 fans.
^very true. unfortunately the shipping size/weight=cost would be about 50% more. In any case the SP20 is quite reasonable when its running at 1200GH or less. I wonder what the comparison of the shipping size/weight/cost of changing the specs of a SP20 to run cooler would be compared to adding the weight of water blocks, tubing and radiators to the box? More if its a sealed system with included liquid. |

Hopefully we'll all get paid out now  LOL |

Phew.. block found.. that was a doozy!

since i started to mine @ ban s0br pays up till the recent bad luck streak. imo, the hack issue has been sometime so not an excuse.
Like Eleuthria, I'm not saying this is what happened here but it's worth noting that many scams used an alleged hack as en excuse for why they couldn't pay their users as well. I think that, and Eluthrias comments are beneath both of you tbh. |

. Actually pretty weird for me as I am in kano's pool = bad luck right now and was in ban's pool still bad luck.
So it's all YOUR fault!  |

For those who have mined with BAN before. What is the longest run you've seen without finding a block?
This is it. CKPool is at 68+ hours without a block and it had double the pool hash rate than BAN. This dry spell for BAN is really going to hurt getting payments to the miners on the pool. BAN Time Since Last Block 134 hours 40 minutes 40 seconds |

which one of those SLOTS labeled as 1,2,3,4 are the slots that power the back chips ? Thank you ! Slots 1 and 3 powers the two back ASICs on each board Back being farthest from the fan or closest? |

Make sure you only access the spondoolies box over https otherwise you are passing the credentials in clear text.
That is a good point. I wonder how many people actually put https when checking their remote machines? My remote devices are only accessible via my IP, and https doesn't work. Not sure if that's a Bitmain limitation, or a host limitation. (I don't have any spondoolie hardware remote just yet.) M spondoolies works over http AND https by default Natted and firewalled but still I access via https |

Is there any software I can use to monitor all my 6x SP20's which are remote? Other than going into them individually via ssh?
I just added support for this to my miner monitor app. It uses the output available in /monitor.php. Neither API nor SSH access is required. Again, this is a Windows .net app. https://bitcointalk.org/index.php?topic=596178.msg10250108#msg10250108M Make sure your app uses https otherwise the credentials to access the miner are going over the net in clear text. |

I have hosted and purchased miners from Mr lee in the past and would not hesitate to do so in the future.

Have you tried swapping the power cables and seeing if the disabled board depends what socket the cable is plugged into?

So it looks like I have a problem with one of my units - the fan stays on 80 no matter what I select in the UI. I've factory reset it a few times, tried on different firmware versions but no matter what I change the fan speed to it doesn't actually change the fan speed. I even looked and the mg_custom_mode file via SSH and it reports the same value as what's in the UI.
Not sure if it's the fan itself ?
I don't really want to open the other units and take a fan from another to test this
Someone else had the same problem, its probably a wiring issue or a problem with the fan itself. Open a ticket with support and they should be able to send you a new fan |

How long until you take our money like everyone else?
Why should we trust you? You literally have no history.
Guys its a 6 month old thread |

Temperatures should not be let to rise above 70C Where did you get this information?? Is it from Avalon chip's datasheet? No, its just a sensible number. Chips are no where near any boundary under stock cooling as it works so well. and you will need a typical computer PSU with 4xPCI-E 6 pin power connector I'm wondering why does they put 8-pin connectors on miner's boards?.. Thanks for the nice guide and photos. I liked the '360 deg' view photo.
As Rabinovitch said, the power connectors clearly look like 8 pin and not 6 pin PCI-E.
Cheers
Correct, they are 8 pin however to keep from confusing people I refer to them as 6 pin as that's what they will have seen on every other miner and are familiar with. If they already know the difference between 6 and 8 pin, then they don't need the information in the first place. Its a bit of a catch 22. You could probably also get away with only 2 PCI-E 6 pin, and even on one cable strand if its 16AWG, but again if you're in a position to use a more extreme arrangement then you likely already know that. So you should use PCIE 8pin? Or you can use 6pin? Whats the manufacturers reccomendation? It does make a difference as you need to be sure when people buy their PSU's for these. |

Thank you !
Judging by the ASIC stats page the bottom two sockets. But for 100% certainty you should ask Zvi in the main thread. Or just test yourself by unplugging them |
