I have two Delta fans in a push pull configuration. SO MUCH QUIETER.
Awesome. What fan models? Delta AFB1212SHE-PWM 2 of them in a push/pull. they work great. $20 a piece. Way quieter than stock. Even a single Delta AFB1212SH works in push, which makes it a $10-11/miner mod and it is quieter than 1212SHE and way quieter than stock. |

Not sure how bitcoin core will be maintained AFTER one year Oliveir's donation ends. I think that industry has to pick up the slack or 10% of miners fees have to be allocated to maintaining the core PLUS fees has to increase approximately three-fold, which is unfortunate, but doable. |

Unacceptable - I was raised on a farm, the son of an English teacher and a carpenter. We had books and projects, no video games. I was one of two CompScis in my graduating class at college that didn't play regularly.
Biodom - no, it's called "Dairy Queen". Pretty great stuff.
Also, I was supposed to have the evening off but it turns out that sitting on the couch is super boring compared to working on awesome stuff. I'm gonna try and build a regulator tonight.
don't play games, but using internet to browse is my weak spot, i admit, but if not for this weakness, i would have never heard of bitcoin, for better or worse. Cheers |

If by "salad" you mean "fried potatoes and ice cream", then yes. We ate lots of "salad".
fried potatoes with ice cream...you guys are the worst  |

Well, if you know me you'll know I'm outspoken on three things above all else.
1. Video games are a foolish waste of time, and that energy spent on entertainment could be better spend on building awesome stuff.
2. CHEESEBURGERS
3. Butts are funny
The third thing doesn't really enter into this discussion substantially, except perhaps peripherally that cheeseburgers come on "buns" which are especially humorous when delivered in pairs. But yeah, no video games are being bought with the sandwich fund. Friday's cheeseburger day comes out of my own pocket, but I will note that the crew ate dinner on Wednesday from the sandwich fund and two-thirds of us ate cheeseburgers.
^^^ i hope that at least someone ate the salad...all that grease is bad for you...but it tastes so goood  |

I don't know where do you live but I don't think 1.2m$ is enough for retirement in anywhere. I would wait for at least 10 millions.
1M is enough to retire in Medellin, Colombia 1mil is enough in most of US, providing a few simple conditions: 1. Your children are independent and DONT leach off of you. 2. ~50% of your expenses are covered by Social Sec-very reasonable to expect $1250-1400/mo for each (H+W)=$30000-34000/year for husband and wife nuclear family (kids would probably leave the nest by then). Therefore, you would need to provide just 18K-22K/year from that 1mil to match average family income in US, which is 52K. It is not a life of super abundance, but with mortage gone, it may be better than most expect. $18-22k is quite possible considering that SAFE withdrawal is supposed to be 4% or 25K for 1mil in savings 3. your home is paid off 4. your RE taxes are small or subsidized-true for many states (for 65 and above). As a sad comment to above, the average 401K (typical retirement account) in US is 14 thou and average 401K of those 55-64 is 104K, so almost nobody will have that million. |

In the galaxy (maybe far far away in time and space)
"It is the year 1006 ABC (after block chain) or 3015 according to the old calendar (AD) that is becoming popular again.
The merger of man and machine is complete.
No longer individuals have to experience death as their neural network is being constantly backed up and stored for possible restoration after an accident.
Young Tith IV is leaving to form a new colony on Uruth, a newly terraformed earth size planet 30 light years away.
As has become a custom over few hundreds of years, Tith will carry with him a new sidechain worth ten thousand bits (million satoshis), an unimaginary large sum that would be required to jumpstart the mining economy on Uruth. Once on Uruth, smaller denominations for the local economy will be circulated.
A parting ceremony and the retirement of the funds from the Earth based blockchain would be attended in person by at least a million citizens of Argoa, a sea steading community which is financing this particular colony, and is expected to be watched by more than 100 billion individuals all over the solar system. After all, such event happens only once a year when a new colony is initiated and funded.
We have more than a billion planets to our disposal in this galaxy alone and need to proceed cautiously as to not deplete our precious capital. We have time."

Interesting. Batch Five is now sold out.
yep, they are probably massively producing it and hashing in their new hosting center. good for sellers in the aftermarket |

What's the minimum per fan CFM on a 2x fan setup?
I'm able to run at a frequency of 250M hashing almost 800GH/s with two old PSU fans. These fans can't be more than 20 CFM each. This thing seems stable just below 50 deg.
If you want to run it at default freq (350) you need minimum 200 cfm in my opinion. Something like 2 120 cfm fan using a push pull setup should work. Be sure to be below 60 on each blade. I am running a 113 CFM fan (Delta AFB1212SH) in push at 350 with temp only 61/57 when ambient is at 30C. I am sure miner temp would be even lower at lower ambient. I might try push pull or leave it as is since I am very satisfied with much lower noise. See my detailed post a page or two above. BTW, it is a legend that you need to be below 60C, stably below 65 is fine-I run S5 like this (at 58-62C) for months before using Noctua. AFB1212SH is 40% of the Noctua price. |

One person, today recieve BrandNEW S5 from 5th batch... look (right blade)
That kind of pisses me off. You pay for something you expect it to be new. WTF? I bet that right miner has been used for at least a month. It is a completely different design too. Isn't there some kind of consumer protection that you are expected to receive NEW and UNUSED hardware? No where is it stated that the hardware is used or refurbished. Looks like Antminer is trying to slip in used miners. That's a whole level of low and just bad business practice. Can Bitmaintech share with us why your loyal buyers are getting used hardware? It's probably from one of their data centers. They mine with them for a while until the machine paid for itself (not long since cost = manufacturer's cost) and then resell at full retail. So no cares? Everyone here just talking about fans. I think they are missing the important information and a little delusional. you think that you are the first one who posted this? most people don't care much (maybe a little). If you had a DOA miner or miner with some difficult to reproduce ailment, then it matters. A bit of dust? people here are mostly (not completely) indifferent to this. |

I am concerned that bitmain has my coin but havent responded with a confirmation that I paid (even though my payment shows it went in 5 minutes after I ordered it) - does this mean they are going to take my money and not give me the product I ordered?
I have the same problem today, I paid by BTC at around 2:30PM , it is now more than 3 hours later and my order shows up as unpaid and expired. I used my blockchain.info wallet because I think Bitmain also uses Blockchain.info wallets... anyway I emailed them and opened a ticket but have not heard anything back. I do have screenshots of the transaction and of the block explorer showing the exact sum in their payment wallet. don't worry yet. if tx is on the blockchain, they will adjust it manually within 24 hr. |

Got some success with a new fan: AFB1212SH (notice that it is NOT a SHE, but SH), which is a 120X120x25mm fan, much lighter. see http://www.delta.com.tw/product/cp/dcfans/download/pdf/AFB/AFB120x120x25.4mm.pdfI only used it in push, will try push-pull later and see if I can boost mining to 1200GH or even higher. The fan is supposed to be just 46db, bit in reality miner is at 60db at one foot distance. It has a very reasonable sound-wooshing, not banging or whining. 60db vs 72dB with default fan is very very noticeable. the home is much quieter now. This fan produces an airflow of 113CFM, which is slightly better than Noctua 3000 for 40% of the price and the same or better noise profile. As you can see, I got 1150Gh with ONLY 3000 rpm (see picture) at ambient 29-30C (my mining room is hot) and reasonable machine temp (59-62C). the best is that you can get one from slovakia or china for $12.99-13.99 or two from slovakia for $20-21 shipped (or ~$10.5/fan). the bad news is that it took the item 5wk to get here from slovakia http://www.ebay.com/itm/2pcs-AFB1212SH-Delta-Computer-Case-Power-FAN-120x120x25mm-12V-0-8A-Speed-Control-/131340504690or http://www.ebay.com/itm/Delta-fan-AFB1212SH-12CM-12025-120-120-25MM-12V-0-80A-Cooling-Fan-Good-Quality-/181703501814in addition, the sleeve is too short for the cheaper fan from slovakia (chinese fan has a long connector, but i used slovakian's), so you have to get a PWM extension cable on Amazon or elsewhere-cost $2-3.  |

I'm starting to think these miners should have been what the C1's were.
They run with that open-built extremely loud full speed fan and still are over 50C.
Even the SP20's at Fan speed 50 are more quiet than these things.
I will use a new cheaper mod tonight-we'll see if it works. ~$20-24/miner. Lowes in my area is completely out of pan M4-0.7 35-45mm screws. had to buy hex. I surmise that S5 modders scooped them all up, LOL. |

My new batch 5 S5 is 'new' (definitely NOT used) and so far everything works-'knocks on wood'.
it looks about 2-3db less loud at ~71-73dB at one feet (in comparison with ear busting batch 1), but maybe this is more wishful thinking than anything else.

Nope. I set a limit as to what I was willing to spend and how many coins I thought would make a difference to my life in the future if it really took off and stuck to it. If I want more then I'll earn it or trade for it.
If it dies, so be it. I'm not going to chase it downwards. The idea of spending more to reduce a loss doesn't really compute for me.
yeah, my feelings exactly. Not going to chase it. If it is going to make it-OK. If not, then it would not. Averaging down does not work in 80-90% cases on the stock market as well. |

i have been thinking of buying this hardware .. what you guys think its still profitable ? how long will it take to break even
Go for it, but think about it as a learning exercise, or as a hobby, or as a long shot of making lots of money in 10-20 years. It will not make you much cash in the short term. |

For myself. If bitcoin went to $0, I probably would be very sad and a little pissed off. Economically I would be hurt slightly but nothing that would make me suicidal.
same as ^^ mostly sadness that another ostensibly good thing did not pan out |

One of my SP31 is not behaving very nicely. Actually, it is hashing with a maximum of about 1 Th. I have access via ssh, and looking in the logs, I see the following - well, it asks me to disable "one by one". How can this be done through ssh? Or has anybody an advice what I should do? Mar 28 00:06:14 miner local1.warn minergate[1737]: Critical: Asic disable 15: Loop RT loss - disable us one-by-one to find the bad one
Mar 28 00:06:14 miner local1.warn minergate[1737]: Critical: Asic disable 16: Loop RT loss - disable us one-by-one to find the bad one
Mar 28 00:06:14 miner local1.warn minergate[1737]: Critical: Asic disable 17: Loop RT loss - disable us one-by-one to find the bad one
I have one like that where it seems that its only stable once i manually disable at least one asic from the 'trouble loop', and it generally disables 2-3 more for failing BIST, then becomes reasonably stable. go to settings, and one of the lower categories allows you to DISABLE specific chips. disable 1-2 at a time fromt he trouble loop, as the issue is sometimes a chip and sometimes poor power delivery I _guess_ it is poor power delivery. Right now I see it running with 4.2 th/s. Nevertheless, the issue is that I have only ssh-access to the miner at the moment. In /etc/mnt I see the file "mg_disabled_asics" with the following content: 0:0 1:0 2:0 3:0 4:0 5:0 6:0 7:0 8:0 9:0 10:0 11:0 12:0 13:0 14:0 15:0 16:0 17:0 18:0 19:0 20:0 21:0 22:0 23:0 24:0 25:0 26:0 27:0 28:0 29:0 I assume that it should be possible to disable the ASICs here. Or am I totally wrong? And IF it is possible to disable asics, would "1" mean disabled and "2" removed? you can disable individual asics in gui |

You can buy them brand new for $320 USD. The original poster is an idiot if he thinks he can make $300 profit with a product thats already in high supply with little demand. ^^^^LOL about $320-maybe if you buy 500 of them, otherwise it is $387 (with shipping). Amazon link shows $519.99 instead of $499 |
