ANTMINER C1 Discussion and Support Thread

[notlist3d]

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.

ok cheers for replies!

yeah i can get some great coolant locally through these blokes - http://www.pccasegear.com/index.php?main_page=index&cPath=207_160_301&zenid=a4d940bbc49b2e11ffb4c6443805eb53

is the tubing length supplied with the C1 adequate or is it beneficial to have a longer length?

Also how is the assembly of the cooling fans/hoses/attachments with the supplied gear, any extra things that makes install a breeze needed or is it all pretty adequate?

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.  

• Order a extra pump (I went to ebay to get from closer location)
• Order a molex to fan power board (example http://www.amazon.com/Phobya-4-Pin-3-Pin-Splitter-Connection/dp/B007S3T4O0/ref=sr_1_3?ie=UTF8&qid=1415897694&sr=8-3&keywords=molex+to+fan        this is just 3 pin, the pumps they use are 4 pin, but they run off two through harness

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.

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)

Hi guys, i'm be interested for the cooling system of C1.
Can i buy the cooling system in Germany?

For a C1? If so, C1s now come with the cooling kits. If not for a C1, you can buy it from syscooling's website still. Links in my #2 post.

Any coolant designed for 'PC' watercooling will be fine. Plenty of barbs and tubing, you won't need more.

You can't buy it from Germany, but you can buy it shipped to Germany. http://goo.gl/5nrxjg

You won't get the same, but I've discussed the issue already with aquatuning.de - they basically have the right gear in stock, however, more expensive...

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.

In the harness the 4 pin pump goes to 3 pin anyway, there isn't any PWM control being used. You 'need' a 4 pin otherwise the plastic gets in the way.

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#blank

Do you own a C1?

[notlist3d]

I have 10 AntMiner C1 Coupon 50 USD off that expire 11/30/14.   I am happy to get rid off them for .01 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 .01 is donated per coupon you want I will send coupon or coupons.  Currently that is around 3.25 for 50 off.

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.

Or...we could just answer the questions:

1:  4 PCI-e connections (6 pin) are required -- one for each of the four mining boards.  There are a total of 8 PCI-e connectors (two on each mining board)...you just need to use one on each board to run at stock speed....so fill up one "slot" of 4 PCI-e connectors on top of the miner.

2:  Check out the harness carefully, I cooked at least two resistors on a board and killed a fan header because one of my two harnesses was bad.  I may do some reflow work to replace the resistors, but in the interim have replaced the harness with a few 4 pin fan splitters from the working headers.

3:  No, you have to remove the miner's cover to plug the provided wiring harness (or a replacement splitters / harness) into the 4 pin fan headers on the mining boards...I have already suggested that this sucks and should be an easy improvement for BitMainTech for future C1s.  That said, it's just 10 standard phillips head screws to undo and pull the cover off to get to the fan headers.

4: The RM1000 is recommended, but I assume you mean one RM1000 for EACH miner...right?

I had 2 boards fry aswell.  Can you confirm your's was done by syscooling v1 harness?
