problem with running in series is that you would likely see temps on each unit increase in succession, with the last unit(s) having the coolant entering at already-high temperatures and offering insufficient cooling. To avoid this, the flow rate (and thus static pressure from the pump) would probably be too much for the C1 waterblocks.
better would be to use a properly-valved system to run them in parallel. A valve on each C1's loop would adjust for any pressure/temperature difference between units.

Depends on the restriction of the blocks, but I'm guessing they aren't terribly restrictive. Flow rates wouldn't have to be excessively high to get reasonable performance in a BTC mining application. The specific heat capacity of water is ~4200J/(l*°K), or 4200(W*s)/(l*°K). To find out what flow rate you need to move a certain amount of heat with a specific temperature rise, it's just P/(C*ΔT) So, if we want the outlet temp of the 4th unit (and inlet of the 5th) to be 30°K above the inlet of the first unit, with the first 4 units dumping 4kW of heat into the water (which is way more than you'd actually see) you'd get the following numbers. Flow = 4000W / (4200(Ws)/(l°K) * 30°K) Flow = 0.03175l/s Flow = 1.9l/min Not sure how many of these dogie has, but it'd be a cool test to do anyway. You wouldn't even need to use that rad, you could just run three of the 360mm ones he sells in series, and maybe a couple of the pumps to generate sufficient head. *Edit: That's a minimum flow rate to keep the inlet water temperature of the last unit at a reasonable (say 65C with 35C inlet water) temperature. Depending on the block design you might need a higher rate to actually get 1kW per device from the block into the water. When you have multiple restrictive blocks in parallel, you will not have bottle neck in the system. I dont know why ppl even consider series in this case. Ppl really overthink this. You can have multiple loops with common coolant and heat exchange (ie. 1 pump for each C1, one giant rad - NOT in series....) |

How would you run 5 independent loops off a single channel radiator?
In series, just like I used to do with 4x GPUs. Can easily dissipate 800W+ of heat on the standard 240 rad I was using back then. We don't have 800W of heat, we have 5KW of heat - you simply cant get the flow rate required to do that in series before you get to the radiator due to the internal diameter of the tubing [and pathways in the heatsinks]. You also dont need "specialized" coolant for any sort of watercooling, distilled water changed regularly will work just as well, at $.99 per gallon at your local store if that much.
As usual, I recommend the safe options because lets be honest, what percentage of people are going to decide to spend a few hours to drain, flush, clean and refill their multiple C1s? You will notice I stated a standard 240 rad... that 9x120 rad with push pull could certainly handle 5 of these in series without issue. Infact... I might just do it. You can also use a power powerful pump as Mr Teal pointed out. Ive been in the WC scene for a LONG time, built over 100+ machines needing to dissipate 1000+w inside a normal ATX case, and those parts were much more heat sensitive in delta T than ASICs generally are. By my rough napkin calculations, a radiator with reasonable airflow should be able to dissipate a maximum (ideal) of 900w per 120MMx38MM Rad, giving you a theoretical maximum of 8100W dispensation for that radiator. Obviously I am intentionally ignoring things like airflow and water flow rate, but you get the idea. problem with running in series is that you would likely see temps on each unit increase in succession, with the last unit(s) having the coolant entering at already-high temperatures and offering insufficient cooling. To avoid this, the flow rate (and thus static pressure from the pump) would probably be too much for the C1 waterblocks. This is what I'm saying. Its not a case of ramming a more powerful pump on it because the heatsink's paths are so restrictive. The minor losses alone would be absolutely huge, nevermind the major losses while trying to pump at high enough velocities to get the last 2 C1s cool. But its also irrelevent, because you're going to need an insane insane insane head pressure to overcome the losses AND get a sensible flow rate. tldr, just buy 5 of these $50 kits and its k... LOL, master of Mechanical Eng eh? ..... What a clueless dumbass. The fluid pressure in a closed loop is all the same. The system as a whole has pressure losses but the water pressure at the first and last C1 is the same. I would ask your "imaginary university" for a refund if i were you. |

LOL at the armchair engineering talks....
Here an idea for you "engineers": use BTU..... and stop using marketing BS by PC cooling vendors.
btw, why waste time on this when you can earn money by just buying BTC at this low price?

Okay so my B2 S4 arrived yesterday, plugged it in, manually set difficulty and I'm off to the races - no problems.
Got the email about the PSUs - confirmed shipping just now for a new one, but in the meantime, do I need to be worried about the PSU I'm currently running burning my place down??
As long as you can have watch your miner..... Better safe and get Fire hydrant and smoke detectors. Dont leave the house unattended. Unfortunately I set it up and went to work, finding out about the PSUs afterwards. Hopefully I still have a home to go to. lol In my early mining days, ppl actually burned their home with GPU mining due to PSU failures. You should look into fire detection at least. I would personally not risk mining unattended until the new PSU come. |

Yes its toxic because i hate lying POS like you? and expose your lies? Do you see me ever posting lies for my own benefits? lies to get donation? This is all started because you reply to me that i've mistaken you with someone else. Many members here long enough can recall your early posts. I never even replied to your early posts, I read it and chuckled: pathetic liar. So guess why i call you out now? ..... And you dare to call me a liar? : I've already said this is off topic 10x but he won't stop spreading lies about me, so I have to disprove them.
If you were able to read english, you would understand that I was replying to the statement "why don't you have lots of money". I was saying that those two degrees are expensive to attain. I have attained one of them so far.
Why you're randomly [and badly] bringing up 18 month old posts I have no idea. Go post in scam accusations.
NO you did not you little lying piece of shit. You got a master degree in less than a year? from MIT? while living in your mom's basement in UK? The fact that you lied to get ppl to "donate" money while fcking brag about building a $1Million company at age of 13 does not make you a scammer? There is a reason why the forum prohibits begging now, to block fcking pathetic liar like you. There is nothing random about you, everyone here long enough knows what a joke you are. More off topic stuff, but forced to reply to the lies... 1) Yes, I have a masters in mechanical engineering - you just repeating "no" does not remove my degree :/ 2) No its not from MIT 3) I've been financially independent from my parents for the last 7-8 years. 4) I never lied that I was/am/will be paying for college.... 5) I've never forced anyone to donate, even for any of my guides... 6) If people want to donate, they can do. In the last 18 months donations have not exceeded $200 or so. 7) It was in £  It was sales. I don't know about you but I don't want around donating companies by their net worth. 9) Post a scam accusation, this is all off topic. You need to script your lies little better asshole 1) repeating that you HAVE Master degree WHILE begging for a college fund = you're a lying cunt You have a BEng in Mechanical Engineering? I have a Masters (MEng) in Mechanical Engineering, you are a million miles away being qualified for this - you're going to have a rude awakening once you do more research. [I too I am unqualified for this....]
Note the date of that post? Then stop complaining. I had £12 in my bank account. Was bored, started my own £1M company at 13. Do something about it other than complain. In either case, why do we have to hear the QQ?
Paying for college: 15UhE4x7d1hD2o2YKCcdddzuhymsTKdeuz Ah internet... 4 years of engineering and a 2 year MBA at Harvard/MIT = big bucks. Your attempt at logic was a good try though. Yet still lying....? 2) But you said Master degree from MIT is expensive. Are you admitting your lies to get donation? 3) Ofcourse you've been financially independent.... right....  . My point is you never attended or even got admission to MIT/Harvard like you said when you looked out for donation 4) Every liar says they dont lie. Whats new? 5) Scammers ofcourse dont force their victims to send them money do they? They lie and mislead ppl to send them money. Thats how it works Mr. Master degree 6) Nobody knows how much was "donated" to you, so why bother saying X while you're already caught lying? 7) Thats not the point 8 ) Sorry i cant comprehend gibberish. 9) Lets not have everyone here know about me, i'm not a liar. Notice i never ditch your guides because i thought you've changed ..... Until your recent balantly BS posts in Bitmain's thread. I didnt even want to reply to your post, i replied to a fellow hero member who recalled what a joke you were..... |

Why is everyone so offensive to Dogie? :/ Think he does a good job
He used to be a an arrogant mouthpiece, so it's likely he takes flack from his past dealings. He's been trying really hard to chane that and help people out so I cut him some slack. Others, not so much. Yes, anyone here long enough to recall Dogie's investment scam? LOL i bet the fcker delete that post now. How are your multiple successful businesses Dogie? To everyone else: [Can we move this conversation to one of my threads, not the Bitmain one please: https://bitcointalk.org/index.php?topic=456691.0] Oh noes.... you fcking did not..... i would fcking crush you little piece of shit By "investment fund", should i say ,..... " college fund" ? You think by deleting your post, many wont recall that? Look, ignore the troll. Dogie claimed to have made a million when he was thirteen in another thread, now he has a signature begging for donations for a 'college fund'. In reality he has a batch one or two Avalon that got delivered on time and has bought and sold ASICminer blades that he mined for a bit. It's also worth pointing out that a 'dogie' is a motherless calf (cow), and not a puppy, which would be spelt; 'doggie'...
Fact is you make an order at a particular date in which a buyer and a seller agree at a fair market price of a specified item at that time (which was before the major rise in BTC value), both are content with the deal. The seller now has responsibility in ensuring every aspect if that deal completes smoothly and in it's entirety. This has not been done. It has also not been done with in a significant time period resulting in a huge detriment to the products life cycle and overall reward.
The seller is clearly at fault and has not fulfilled his obligation to deliver an agreed volume of said products within a reasonable timeframe.
The buyer has every reason to vent their frustration and negativity towards the seller responsible.
The fact BTC value has changed within this timeframe is irrelevant to the sale and delivery of the item on the sellers side, though understandably for the buyer it is massively important. This has nothing to do withe greed as the buyer could not possibly predict the future actions of the European Central Bank in forcefully demanding the Cypriot government steal from it's residents and the ensuing media would have on Bitcoin exposure and subsequent BTC value.
Many times, you claimed to be Master Engineer....., you always started " I'm an Engineer.....blah blah,.... so you should fcking listen to me ....blah blah", while you cant even compute a simple power consumption. Anyone can read this thread, and see what kind of person you are https://bitcointalk.org/index.php?topic=256507.0Some of your golden shit :
RAIN THE HATORADE ITS DELICIOUS.
If I ordered 5 (which I didn't, I ordered 4), received 3 and they turned out to be worth $300000 each (proportionate), of course I wouldn't be calling them lying scum! I'd be stfu'ing and enjoying my money.
Greeds got to greet.
In the future, remind me to do business with you.

In our future business dealings, I'll be taking your money and then saying "fuck that shit" to holding up my end of the agreement. You best not complain because that would just be your greed showing through. ZING All of the hero and legendary members should remember your BS posts. Lucky for you, they're no longer active and this section is full of noobs. |

Here's the recipe for fairly secure storage of your crypto-wealth: - Linux operating system. Updated, running rootkit/keylogger detectors from time to time.
- Encrypted wallet(s), keeping the passwords in head or keepass.
- Daily backup of wallets to 2 other locations, over the Internet. Fwbackups is good GUI option that uses rsync/sftp.
For extremely paranoid people, cold/offline wallets or paper-wallets, but that's a bit of an overkill, I think the first method is 99.9% safe.and 100% of false security. Any wallet thats online, encrypted or not is not safe, period. Luckily, we have multisig wallet so you can atleast keep one private key offline only for signing tx. |

I saw it in the Chinese section too. It's kind of hard to believe, since Blockchain just got a lot of money from VC.
This has nothing to do with Blockchain.info, idiot. The whole wallet encryption and decryption is done client side, bockchain.info doesnt store shit. |

This person has probably been attacked with a man in the middle attack. I think he has used a malicious TOR exit node which was sniffing his traffic. They then messed with his SSL certificate to blockchain.info. Because of this the user was logging in at blockchain on an unsecure (HTTP) connection. The attacker was able to sniff his data, and get the password. Im doing researchs to these attacks as we speak. Very frightning.
This would not work. Everything is done on the client side as far as encrypting and decrypting the wallet, creating new private keys and signing TXs. If the SSl certificate was tampered with then he should have received a warning. The only thing a TOR exit node would have been able to do is stop the TX from being broadcast or prevent the user from accessing his wallet. IMO TOR had nothing to do with the fact his money was stolen (if it was in fact stolen) They can even inject fake SSL-lock icons inside your browser. Not much people will notice. you dont get it do you? lol at your research... look like you have to spend alot more time. |

Theft of any tangible property is illegal. Period.
Yes. If the state does not recognize that Bitcoin is the property, then??? I'm pretty sure that if your Bitcoins are stolen in China, the Chinese authorities will not seek criminal. So it isn't illegal... Or I invented an even better example: Drugs are illegal almost everywhere. So if someone steal your drugs, it isn't illegal. Because it will be not punishable by law. Because no one go to the police with a statement: "My drugs are stolen"  Hey dumb fck , might as well use North Korean as your example. Your analogy about drugs speak volume about your intelligence. |

Alright, since the general consensus is that stealing bitcoins is illegal.
If I discontinue the use of communication with said person (from a way that can be linked back to my IP address) and continue the conversation on an anonymized, encrypted email, with TOR, a VPN, and tails, and then execute said plan, law enforcement would have no way to prove that it was me who committed the crime and I would not be held accountable due to lack of evidence that it was me, correct?
I think you're try to plan to steal BTC of something else with monetary value; so, I shall stop giving you legal help to avoid being held responsible of aiding someone to commit a crime. Go earn legit BTC instead of trying to learn to be a scammer & thief. No, I just want to see if this is true. Because if it is, then the illegality of stealing bitcoins wouldn't even matter in retrospect. If you can simply anonymize your connection and not have anything linked back to you. What kind of dumb shit are you? If i come into your house, rape your mom, make you literally lick her shit off my dick and take all valuable goods, then leave without my trace of identity (i wear a mask ok? ). It doesnt matter what i did was a crime or not right? Because police cant prove its me that do it right? DUMB fck were your mom gangbanged while carrying you? |

Over 30 minutes for a single confirmation does not (and will not ever) work in the real world. (Almost) Every time I start to believe that BTC is "going mainstream", I have a delay waiting for a 30+ minute block....  BS, its called variance. I have always got confirmed within 10min, some even in secs ..... What does that tell you? Look at the avg block time, you've been this ignorant b4. Sell your coins and fck off? |

I think they are smoking weed here. My best case scenario is about 10-15% of the Gold market size - which would equate to about 50k per coin at 21mn
LOL did you just pull that shit straight out of your ass? Bitcoin is not only a commodity, its a platform for every securities. |

Of course I still buy hardware but I am smarter than most miners... I come from Gold Mining, my secret advantage  Right now, someone who owes me a lot of cash that cannot pay me back in one shot, mines for me until debt is paid... Hint Hint?!?! I did the same in Gold Mining... put those deadbeats to work for free. In the meantime, I buy mining hardware and solar on a 1:1 ratio; meaning I buy 1 Watt of Power per 1 GH/s. I don't sell coin under $500, period, don't need to. By the time the debt is paid, I'll have a solar plant able to run my mine for a few days without sun. Most first world countries have government programs for businesses/companies to increase power efficiency or get a portion of it paid back. You can also claim power as business expense and should!! I mean, if you're too lazy to do your homework, learn some history then don't mine for profit, mining is a privilege, an opportunity, not a right. Today, 99% of new miners will fail at profitable Bitcoin mining; your best bet is to mine an AltCoin and hope it gains 100x its Bitcoin value. This way you mien for nothing but at least you know and have a chance at the "Overnight Superstar Altcoin" and make tones of cash from it. Bitcoin mining seems to have a knack at luring lazy clueless people who just want money and do nothing for it; go read asic builder pages lol On the other hand, we're in the the Great Bitcoin Rush, that in itself is humbling enough to want to mine at a loss no? Price would have to go down to $100 for me to stop mining, when it gets too low, I put my chance on another coin and hold it. I'll buy hardware until manufacturers are fed up of selling to me. Right now, nothing of real value to buy with Bitcoin.Are you stupid? You sound like an idiot with fantasy about "mining secret". LOL what a joke. |

I think they own KnCminer.
Why do people hate KnCminer? Delayed / failed delivery promises? The press on them seems pretty positive. are you fcking retard? The press does not know shit especially when they're paid to write. KnC is a scammer, go buy their miner and see for yourself ? |
