I paid for 2 C1's. Just waiting for them to get shipped to me. I'm in the US. Already have the power supply and extra coolant. I've used the Corsair RM1000 on my KNC and it is a flawless power supply. I'll be using that power supply. If there is no electrical issue of using the supplied harness then I'll just use it. I assume it just plugs into one of the plugs on the top of the C1. This is my first antminer, so I don't know much about them or where power connections are, etc....I actually see 4 PCI-E connectors on the C1, but only 2 are needed to power it I guess? And I'm surprised you found that 4pin block. I searched that site and couldn't find it! You must have better search capabilities then me. I'm just getting impatient, because I want to be up and running ASAP.
No worries i can understand getting impatient. My RMA pumps are somewhere in China... and may go back on the grid one day and make it here. I got impatient and I'm sure it showed. If I let any excess madness go twords anyone I appolgize, it was all meant twords syscooling. |

In a perfect world you use cold storage.
Can I ask is it ok to show IP for security? Or do you have to be anonymous completely.

I have 28 AntMiner S4 Coupon 400 USD off that expire 11/30/14. I am happy to get rid off them for .02 donation. (Set a price as people are bad about donations  and I'm not here to make money just pay for time my C1's were down because of syscooling) PM me if you are interested. After the .02 is donated per coupon you want I will send coupon or coupons. Currently that is around 7.50 for 400 off. if you haven't noticed, coupons are being offered for MUCH cheaper by klondike and me. I think .02, over $7.50 currently, is a lot for a coupon that BITMAIN literally probably issued in at least the tens of thousands range (by this I mean total number of all coupons distributed, not just the number of recipients), if I were to guess, maybe even more. I think it's great your doing cheaper, I just think you will run out within a few days. I'm not in a hurry. And since my goal is to pay for my C1 downtime, if i sell some great, if not I am still thankful of bitmain doing it. I know it made me order.. This is last I speak of it in thread, as I don't want to go off topic or turn into spam. |

Is Corsair RM850 80+ Gold PSU enough for running one Antminer C1?
Yes, although I still prefer the 1000 as an investment if you're buying a new one. I can confirm the rm1000 is great with theses. I had a cold ambient temps and PSU was in its "quiet" mode. I have got conformation I am being sent 2 pumps as replacement's. I bought a molex to fan connector so I don't have to worry about my wire frying boards. All said it looks like I am losing around 2 weeks mining on 2 C1 machines. Down 2 board fan controller's on 2 separate boards. Lost higher priced coolant. Paranoid and bought 2 extra pumps, and molex to fan boards. With extra parts I ordered I am hoping to lose only around a week, but it came at a premium. I will know more when I get all the parts from RMA. I highly suggest 2 things after all of this so you don't lose mining time. i really like that molex to fan power board. those would work great in my pc builds. this is part reasons why i always read these threads. It's working great with it. And no chance of fried boards like with sysgear harness (version 1). One thing to mention is I replaced pump with a 3 pin fan so I was able to do a molex to fan pin board with all 3 pins. If you are using the syscooling pump you for optimum power need one 4 pin for their pump. They do make some with a mix so it's possible to get one that does this. Why would you change the 4pin connection to a 3? There is a reason why it is a 4 pin. The most obvious is for some kind of control. That 4th pin controls the speed and I'm guessing if it senses a higher temp runs the pump a little quicker. Unless there is no logic in the circuitry of the pump at all. It actually would have been easier for syscooling to keep everything 3pin, but I think the 4pin is there for a reason. That's why you can't find any molex power boards with 4 pin connectors on them. Well I choose one that shipped close on ebay. It actually runs faster the original pump. Original pump harness does not use 4 they cut off the side of plastic to rig it..... so you didn't get 4 with it. And yes... you can find molex with 4 pin. http://www.frozencpu.com/products/25650/ele-1333/Phobya_PWM_8x_4-Pin_Splitter_81136.html#blankDo you own a C1? |

Look at this nice trend. Nice if you're a miner, that is.  Yeah I think low growth is sticking around for now. Well it looks to be at just under 2% with 5 1/2 hours to go It's looking great compared to beginning of change. I will be happy with 2 or less. |

There is ALOT of tubing you have more then enough to do it. I personally went with cutting mine at length it appeared as in syscoolings picture. If you have a winter ambient temperature it seems like it might allow it to get colder with extra space touching freezing air. Best advice with attachment of tube get some hot water. Dip the end of tube a few inches in water. If you get the tube to warm up it expands and is much easier to put on the barb. You can feel the difference it has a lot more flex for a few seconds out of the hot water. (I wish I could remember who said this, someone earlier in thread gets credit not me) |

What constitutes "specialist coolant"... anything with corrosion inhibitors? I was under the impression that using automotive fluids (like anti-freeze) in a loop was harmful to plastic parts inside a pump. I’m wondering if something like Feser Base would suffice. I have some copper radiators on-hand that I’d like to use but mixing metals just sounds like it's asking for trouble.
It's around 10 dollars for pre-made kit I suggest getting it. It is to prevent corrosion among other things. You can make your own yes. But your risking a lot if done wrong. Most common is straight water, no you should not do this. Anti-freeze I cannot say I have heard of tests but I would not want to be the first to try it. |

Also Bitmain sent out a lot of coupons, if you look people sell/give them away on the forums. Right now S4 coupon is 400 off.

Also keep weather in mind. If it is hot you might need to extract heat, and it adds power on this.

Hi Guys
Just ordered 2 C1's with the added $50 liquid cooling pack. Just after some advice on what exactly i will need on arrival, (Coolant and how much?, any other add-ons that people have found useful?) also I need 2 PSU's so just after info on what people are running and results? Also how was everyones ETA on delivery? Mine is to Sydney, Australia.
Thanks
Dogie has a nice link to some cheap coolant on amazon. Amount depends on length you cut cords. I used around 600 ML on both of mine. Order 1 per each C1 i suggest. On PSU I personally love the RM 1000. Works great, downside is not a cheap PSU. Yes you will need a psu for each one, assuming you don't use something like a 2k watt server psu. Time Bitmain is normally very quick. I know if in stock they can get from China to US in 2 days. Which is amazing. (Can take longer if bad weather, or unlucky and customs holds it longer) |

Newly designed fan wiring harness,could be plugged in board directly from outside,and you needn't to remove top cover fo C1.Also 3*3pin for fans and 1*4pin for pump.  Im still a bit cautious that you have a fairly significant power load (3x2A fans and a 2A pump) using only a single wire pair - thats around 90W load and it appears to only be 18awg wire. The PCIe connector is a good idea, but you should make use of the fact it has room for 3 wire pairs, and better distribute the load so more wire harnesses dont get hot or burn through Not as you say,3*0.4A for fans,1*0.5A for pump,totally no more than 2A,the single wiring harness could work well.Our wiring harness could bear less than 3A,we never heard it get hot or burn out.Possible reason might be user plugged it wrongly with previous wiring harness,but with new wiring,this situation couldn't happen any more. I submitted pictures of a burnt board from your harness catching fires.... and you say you never had a report of this? Please just admit your mistakes. Seems like about normal support from syscooling at this point. Are you still testing pumps dry? Can I ask whose idea it was to test dry? I'm done with syscooling. They can continue to spread lies about not getting picture of board that burnt fan controller because of their harness. They sent proof of it happening. I have provided pictures, spoke what they have turned into a nightmare. I just hope others don't have to deal with this. The C1 is a solid machine. I like it alot after upgrading it to a harness that does not burn and a pump that was not ran dry. I give Bitmain thanks for a great machine. Hopefully syscooling will grow and turn into a better company, but with current trend I highly doubt it. And again it is not Bitmain they are great. Syscooling is separate which becomes so clear when dealing with the 2 companies. |
