Hey all

Do you think it could be a good idea for bitmain to do another Antminer CX or not ?
I didnt get the C1 but Im starting to look a little bit more into liquid cooling and I was wondering why Bitmain didnt do other C miner.

Syscooling did the water cooling system for the S5. Was it good ?

Will they do it for the S7 ?

I highly doubt they do another C series.  Syscooling was one of the worst companies there was at the time.  They did things like dry test all of batch one's pumps.... which running dry causes high RMA rate.   They did not test out all the wiring harness's the first batch mine if you plugged it in it started to spark....  And on top of that the RMA pumps one took one month and other over a month, both died within 2 day's of getting pump.

But some did have better luck.  Later batches they stopped dry testing as it was killing pumps.  And they changed wiring harness to different design. 

With most data centers being CFM driven I see them sticking with fan's at this point on.  There will be those who continue to mod miners.   I think mod is only chance there is of a water cooling S7.

The C1 was at the height of the anti Bitmain shilling so a lot of the "problems" were from a vocal minority.

The context was a bad translation, and powering up an impeller for a second to check it works isn't the cause of failures.


A number of harnesses didn't work due to bad crimp connections which I had fixed very quickly. If a harness was cross wired then it wouldn't spark, the PSU would refuse to turn on due to short protection.


Pumps did have a high failure rate, I warned them about that way before release but they went with them anyway. My RMA pumps took 3 days to arrive and they provided a spare.

They gave you the VIP treatment then.  My pumps took a month slow shipment compared to original shipment they used at least for me. Original they used fast (I paid a lot for the kit), the replacement parts though were very slow and did take a month and one a little over.  The harness did spark on the board on fan connector, I offered to send it back they did not want it.  

I won't get into a big thing about it since I'm happily past it.  But if you go through C1 thread you can verify all the issues I had mentioned in it.

I read every post in that thread, I know the issues the C1 had. I just don't like that they were misrepresented to be 90% failure when it was still a small single digit number.

try the ''c2'', 2*s5 in the place of the s3 blades....
got 3 in the house atm, and i'm very happy!

there was also an spondoolies related water cooled product, something with edge. google it or search the hardware section

My recollection about the water cooled Spondoolies  "product" is that it was being produced by somebody else, to do the packaging and cooling. I don't think it ever actually got beyond the prototype stage before they realized their market time was poor. I don't know what happened to them, but I would NOT be looking for any water cooled Spondoolies product anytime soon, if ever.

I doubt that Bitmain will produce another water-cooled product - uness BitFury starts selling such a product to the public at some future point.

 Probability VERY VERY low.

I personally would like to see another Quiet water cooled miner...

My C1-B2 lasted 12 months for me, I did have a pump failure but was only offline for 10 days cause of it.

Thank you Bitmain for the great RMA service on that one...

I just sold my C1 about 3 months ago & i'm pretty sure its still going, Running on Solar power now i believe..

How about a C7 that runs 1 blades at around 1.6Th @ 435w with S7 chips but is totally silent??

Set it at $700 with pump & delivery...

Bitmain - Im in & im sure u would sell heaps with a cheaper unit!

I don't think there is enough demand for such a product from BITMAIN.

Even if BITMAIN does another C series it will be more expensive and increase the ROI time.
