Thanks for the responses everyone! I'm going to leave it the way it is because after running for a while the fan quieted down a bit and it hasn't been loud since, but if I have a problem I will probably cut a whole in the top and mod it.
Thank you guys!

So I just bought a surplus DPS-1200FB and I noticed the fan is VERY loud, is this normal, or does it need a fan replacement? I posted here bc it's bitcoin mining related and I know a decent amount of people here have them. Thanks!
Most of the server PSU's are pretty loud. They have become popular due to you can get a better price going server vs atx at this point. With surplus think of data centers that did not really care about sound. So good psu yes (depending on condition). But something for those home mining... no in a lot of cases. Do you think replacing the fan would work/ be safe? I'd be using something nice like a Noctua NF-A4x10. Don't do that because it might not provide enough airflow and melt The side mounted 120mm sanyo/scythe/delta mod might work here? By no mean would it be quiet but it would be a less high pitched noise? What is this mod? I would be fine with a loud fan, that high pitched noise is the worst though. |

mine aren't once it's turned on and goes tho the power up for maybe 5 mins it's very loud,then i never hear it again. I guess what it's doing is some kind of adjustment i run my two off a 240 line .one had two miners plugged into it at one time it maybe used a 1000 watts or little more.now one powers a Avalon 4.1 overclocked to 1.24 th or so . and other one powers a C1 .
Interesting, I was only around it for like the first 5 minutes it was powered on, so that could be it. |

Yeah they are meant to be as loud as vacuum cleaners.
Okay good to know, because mine definitely is haha. It's also a hot day so that could explain it. |

from what I understand its opposite the coins become more valuable am i wrong?
Only due to supply and demand. To answer question, yes, miners will be making 50% less of what they were previously. HOWEVER, due to the value going up, they should be be helped out by the value going up so high. Mining seems very unsustainable then... if every couple years the reward is halved. But your forgetting next gen gear that will be coming out. Some report specs MUCH less better then 1/2 efficiency so we can make us for a lot via new generation of gear. Which will happen. But it is not unsustainable due to the large mega mines. Even at having those paying a few cents likely still remain profitable. Home miners... yes very much harder in a lot of cases. But it is not unsustainable, mining will continue. Yeah I meant home miners, I am guessing it is going to get harder by a LOT. Still unsustainable in that respect IMHO. But those mega mines like you said will probably remain profitable. |

The reward for minning successfully is 25BTC, after halving the reward will drop to 12.5BTC. So miners will not make as much bitcoins as they used to, btc might become more scarce and its price will rise.
So in other words miners will make less but likely not a HUGE amount less? |
|
|
|
|
So I don't understand the halving very well, will miners just make half as much? Will the price double or the difficulty change? Will bitcoin mining just become so hard it ceases to be cost effective? Am I making a mistake getting into bitcoin mining? Will people just switch to a altcoin? Sorry for all the questions, I'm still learning about bitcoin.

If you want to read the results of my work on S1 undervolting, details can be found here: https://bitcointalk.org/index.php?topic=857967.0Probably not as n00b-friendly a writeup but fairly technically extensive and gives numbers down to below 1W/GH board-level if you want to take it that far. With free power there's no real reason to unless you can't deal with the heat output. Well my reasoning is 3 Antminer S1's = ~360W*3 = 1080W, and the PSU on 120v could only give me 1000W, so if I just pencil mod one of the three I should be able to power all of them with only one PSU and only ~40GH/s loss. Also heat should not be a problem even if I didn't undervolt, I'm going to have 2 fans on each rig. Also thank you very much for the writeup, I will be reading about this. yes but the mod tends to make the sweet spot for the miners to be 130 gh to 160 gh so 390 to 480gh with watts dropping from 1080 to 500-600 is more likely what you will get. but heck since your cost was 10 bucks 400gh will earn 35 bucks before the ½ ing 450gh will earn 38 bucks before the ½ ing 500gh will earn 41 bucks before the ½ ing 550gh will earn 44 bucks before the ½ ing Is that if I mod all three? Sorry its a little confusing to read. I was planning on only modding one. I see you're still struggling with this. You should undervolt all of them, if only to a point where you only lose 10GH/s each. The efficiency will be much better, you wont overload your PSU and there will be less noise. Yeah it's kind of overwhelming, it's my first time doing anything besides a USB Block Erupter. Thanks for the advice, I will see if I can undervolt just little enough to lose like 10 GH/s. Thanks everyone  Just a heads up to how i run my S1's now. At some point, when you have better miners. You only turn them on when you have spare power or need heat (I disabled all heating here). If you undervolt them far enough, you can use them as on-demand heater with no fans = 0 noise (depending on the PSU i guess). Good to know, I'll probably turn them into heaters (like you said) or just sell them on eBay when I get a better miner. |

Depending on how far you undervolt them, you can run half a dozen on the DPS1200 on 120V. I had at one time 14 undervolted S1 running off a single 2KW PSU.
Okay good to know, current plan is to undervolt the S1's so I can run 3 off one DPS1200 at 120v. That's 300W each, do you have any idea what resistance I'd need for that? it is really easy and I will find a link just shoot for 140gh per machine at 180 watts per machine so 420gh total at 540 watts all info is here : https://bitcointalk.org/index.php?topic=526060.0This is awesome thank you. Nice to have the chart. |

If your electrical outlet is over 208v, without any pencil mod, you can power up 3 S1 or 3 S3. If your electrical outlet is at 100-120v, you can power up 2 units. if electricity is free, let the PSU be as is! Would a DPS1200 work for all three without underclocking and/or undervolting?
Not on 120v. But you *really* should downvolt them. The GH/s loss is minimal vs massive efficiency gain. Is it easy? Is the downvolting just via this "pencil mod" I've been hearing about? And I have free power so does it even matter? Also if not 3 could I just power 2 with a DPS1200? Thanks. But with my 120v socket wouldn't I be able to run 3 undervolted antminers on that single DPS1200? Compared to just two normal ones? |

I would say yes, you could use them in the winter instead of a heater and you use them for altcoin launches that run sha to try and make an ROI if ever possible.
And if never use them I still think there are 5 dollars worth of parts within them. And also make a decent thing on a mining area spot as decoration. I can't say for sure how much they are worth in part's but 5 dollars seems like heat sinks might be worth that in some cases. I hope OP bought them after reading thread. I forgot to check this post! @notlist3d I have bought the miners now (ended up getting 3 for $10!!!). But I am still not sure what I could get that would power them all. Anyone know of any breakout boards for the big 1200W HP proliant power supplies that could power 3 (dual blade) S1's? I was thinking of getting this: http://holybitcoin.com/product/hp-1200-watt-psu-board-bundle/I never liked the style of board.. that psu needs 240 volts to do 1200 watts . if you down clock just a bit those miners can be quiet if you do the pencil mod they become very efficient like 1.1 watts vs 2 watts do you have 240 power? Sidehack sent me his new breakout board for testing . it is better made then the ones you asked about. https://bitcointalk.org/index.php?topic=1442707.0I would get one of these and six cables 2 per unit. I would look for the pencil mod thread. I did 430gh at 540 watts with 3 s-1's vs 600 gh at 1200 watts over clock vs 540gh at 1080 watts stock settings. How do I get one of those? Also I have 120v not 240. It doesnt do super good on 120v. Just to be clear, it does not do 1200w on 120V. If he takes the s-1's and downclocks plus undervolts via the pencil mod the hp1200 would be very good for him. If I recall he is a zero cost deal for power. Would a DPS1200 work for all three without underclocking and/or undervolting? |
