Well do keep in mind the miners are disposable. They will be fully obsolete in less than 6-9 months time. So build to junk them. No need for expensive cases.
Strato
Not entirely disposable and obsolete. Some people in here claim that they make some profit or at least break even or recoup some of the capital at a loss by selling off these used up miners. There's obviously a market for it and so it would make sense that having a better case would also have a better resale value. Also, 6-9 months of ownership of these units is a long time to be subjected to high noise levels and to be dealing with less efficient cooling by employing an open-case design as opposed to a closed system like in the S3s. |

"Case" could have been made from one sheet of the same plastic which is used now, holes cut for cables at top and U-shaped square "case" covering sides and top. Every cheap plastic thing is stamped "Made in China" so I think it can't be very hard to find producer for this "case".
Unless the S5s are placed on a solid flat surface in the standard orientation as designed by Bitmain, the bottom would have to be closed up as well (the S3s are). Otherwise, in any other orientation (on its side, vertical, etc.) or in standard orientation on wire shelving units, the bottom would effectively become an opening, thereby defeating the purpose of covering up the top (only). |

if you know how to manage your miners, you can ROI, i bought some s3 and they ROI'ed in 2.5 months including electricity, but if you just point them at a bitcoin pool and forget about them ya, you might never ROI
Could you point me to a thread with tips on what can be done to manage miners to achieve a better ROI? Or would you please start one? rent them out on westhash.com or nicehash.com for example. For example during the whole paycoin scam..eh I mean hype the rates were up to like 0.05 btc per th and even higher....so in 3 days i got like 0.15btc for 1 s3+. considering i paid 0.525 or something, (+stupid ups fees/taxes) |

Ok You are right. I didn't want to send plastic to landfill and used the protecting foam as hashing stand and resonance absorber. After starting I realized that resonance was ny smallest problem. |

Hi all,
So I'm a little new to mining btc with a ASIC miner. I just got my s5 the other day and I have scowered the Internet looking for ways to get the most hashing out of it with a quieter fan. All that aside I think I'm gonna use a noctura nf-f12. Right now I have a sonon 100cfm fan that is not as loud as the stock fan but it is still a bit loud. I also have a second fan pulling at 1350rpm 74cfm.
My temps are 55 and 58 at 275Mhz with 2 hardware errors over a 12 hour period. It hashes at about 900gh/s. I've not been able to get the miner to stock settings with other fans like everyone else on the forum without going into the 60c range which I read is da get zone.
Maybe it's my setup, it's out in the open on its side sitting on my desk. When do hardware errors become a concern? Why is it not recommended that the s5 not be allowed to enter the 60c range when over heating is set at 80?
Also, i love the s5 but I'm afraid of my energy bill. How do you guys pay for energy? Do you convert btc to currency and pay that way or just out of pocket and keep the btc mined?
Thanks, sorry if these are n00b questions and belong in a n00b section but they are about the s5

I pay for power out of pocket and keep the btc. Just consider it as buying btc from your power provider.  |

I have ordered my first S5. Got to see how mining works with them. I have been mining with GPUs now for over a year.
Do you think it is more profitable to switch from GPU mining to ASIC mining via Antminer S5 for example? I don't have to pay for electricity anyways.
Therefore I could sell my GPUs (6x R9 280x and 3x r9 290) and switch them for ASICs. But lately GPU mining is dieing so hard. It was fun early, when coinlaunches were made. But there are so less coinlaunches in last time because of all the scams. The cards have been running on Nicehash since over 2-3 months now.

With free electric, it definitely is more profitable to mine with ASICs than GPU's. If I were you, and seeing you are already with nicehash, I'd get a couple more S5's ..... then you'll be making some serious returns in comparison with your GPU rigs ..... my 2 cents. |

What would be the reason to try these? Being 38mm form-factor, the noise they emit has to exceed the stock fan noise. Try these out ... http://www.ebay.co.uk/itm/Lot-of-4-Compaq-Nidec-Beta-V-TA500DC-A34538-90-Proliant-Fan-with-Dual-Housings-/251820064274?pt=LH_DefaultDomain_0&hash=item3aa1a53e12Strictly speaking, these are not 120mm fans and the holes do not match up with the holes on the S5 mount, but they'll sit nicely inside the brace of the fan on an S5 (even S1 and S3), couple that with a slight mod (using this resistor: http://www.maplin.co.uk/p/wirewound-3-watt-33-ohm-resistor-w3r3 on the +ve line) plus double sided tape to hold them in position and you'll get a humming rig with more than enough CFM. If you put them in a pull configuration, the pressure will also help hold them in place. PS. All the mod does is reduce the voltage to ~7 volts (and thus cut its noise dramatically), so if you have a source with that voltage, use that! You'll need to strip all the housing off and remain with just the fan. |

Do you mean longer blades? That would be true. Have you gotten good results with the larger Nidec fans? If you have to hack up the fan to get it to fit, it seems like it might be more trouble than its worth for a 6% wider fan. |

If you have to hack up the fan to get it to fit, it seems like it might be more trouble than its worth for a 6% wider fan. You read that wrong, I was suggesting that the replacement TFC would be louder because it is the same form-factor (38mm) and spins faster at 5000 rpm. I am not sure the TFC has longer blades, infact, that would be a surprise if it did, however, the Nidec fan is (I think) a 50mm form factor and the fan blades are deeper. Bear in mind that the TFC and stock fan blades are a lot shorter than the 38mm form-factor suggests due to the "spoilers" that focus air pressure, however on the Nidec, aside from the guard, the rest of the space is occupied by the blade(s). On the Nidec fans, I've got fantastic results on both the S1 and S3 (but not run it yet on the S5). I am more than sure it will yield good results as the amount of air it moves is better than a stock S3 fan running at full pelt (not scientific but observational) with the above mod. Physically, you do not have to hack it to get it to fit as it sits nicely inside the brace. Its case holes just do not match those on the S5, but I attach them using double sided tape on the rigs I run it on. PS. Like I said, strictly speaking its not a 120mm fan, more like a 125mm fan (but it could also be a 122mm .... not sure) |

It's a 38mm deep fan at least according to the one datasheet I saw, but 5" (127mm) so the blades would be a little longer. The exact model wasn't in there, so it might be that the A34538 is a deeper fan. Do you have a DS for it? Edit: That might actually make sense. http://www.nidecpg.com/fanpdfs/c2003_4546.pdfAll the fans in there are AXX3XX models. The AXX5XX could be 50mm vs 38mm versions. |

these fans use 4A of current-this is quite a lot. I am not sure that they can be run off of the 4 pin connector on the top of the miner-maybe someone can comment on this. they could be run from the PSU directly through molex adapter, but then they will always blast at the maximum speed (no PWM) |

The exact model I am running is AX34538-90 as read from the sticker (and I believe that is the same in the link I gave), and it is definitely NOT a 38mm form-factor .... more like a 50mm one. I am popping out for a while to pick my kids from school but will look again when I get back and update you. |
