Antminer C2 speculation thread

[bbxx]

Hi.

I have 2 antminer C1 units. They works perfectly.
I would like to expand my hashrate.

Will be C2 produced with new bitmain chips?

If yes, when ?

Thanks

If they produce one. They can include 4 blades in the box for 1180 watts and 2.3T. Or stick with 2 blades like the S5.

Quiet miner with max 1400watt, with 2.something th/s or even 3th/s would be nice!

I dont think they are coming out with C2 so soon, probably S6 first and S7 before C2 came out.

s4 has 4 slots on the controller board, so c2 may come before s6. at least on the market 'cause we can guess they already have s6!

probably not soon - using the S5 blades could be too much heat for the heatsinks of a C1 (1200W+ vs the C1 was 800W)

IMO, would rather see an option that is more like the S2, many smaller blades running efficiently in a server case.

It's more about the size of the radiator and pump. A 6*12cm fans rad will have absolutely no problem to dissipate 1200 or more  watts!

Radiator size [and airflow] more so than pump size. The pump just has to keep up and keep the pressure high enough, as the heat exchange of a block is usually pretty good.

I would love to expand my water cooled rigs with a C2. The peace and quite I have with my C1 is worth the hassle of liquid cooling.

I predict not making a C2. Just hard to compete with price of S5 and air cooling.  I hope I'm wrong as i love a variety of miners.

If they build it, miners will buy it...

I have only 1 C1 and would buy more if Bitmain sold them still up for sale.
Although I don't think we'll see another liquid cooled miner for a while, I do believe Bitmain will build another one.
Each batch has sold, wouldn't see why they don't make another.
Even if they shrink the process significantly, all that means is they can put more hashes per cubic inch.
That won't necessarily equate less heat.
What I noticed most from S1 to S3 was the ventilation efficiency.
However, remove the one fan and it is as hot as an S1's... you just have better control over ventilation with an S3.

Key to a cool mine is proper ventilation.
On the flip side, the C1, you can put the radiator wherever you want.
I think what hurt Bitmain the most was using the cheap SysCooling kit... I ended up having to buy the kit again.
However, I went DarkSide radiator and Swiftech pump since both components either DOA or broke.
Thankfully, I was "mess ready"...
One made with quality components is amazing, the C1 is one of my favorite miners... only next to the S1.

I'd be upset if they didn't make another liquid cooled miner.
Speculation-wise, I would say they would build one with the next process.
If they go at 14Nm then they would likely try to make it close to the power use of its predecessor.
As in, the S3 was double the power and half the process of the S1, had almost the same stock power use but made double the coin.
The S5 uses about 35% more power than the S3, putting out around 25% more hashes per power unit.
Using this logic, a 14Nm chip @ 500 Watts stock would give 1,000 hashes @ ~250Watts...
Or, 2,000 hashes @ 500 watts... of course I am only using approximate math.
However, to keep inline with the C1, they'd be better off to go to a 4TH.s @ ~1,000 watts.

This could benefit from water cooling.
If Bitmain doesn't keep up, another builder will.

Super old bump?

I don't see a C2.  The C1's were just a lot more trouble for bitmain then they should have been, in my opinion.   I do agree a HUGE part if not all of it was syscooling.  They dry tested all batch one pumps, so you got a pump almost dead.   And not surprising the pumps died.

The wiring harness they did 3 different designs as they could not make a good one.  I had one with a crossed wire or something a batch one it would cause sparks.  I had to replace wiring, and pumps.  The RMA pumps one took exactly a month to get, second took over a month.  I was treated horribly by them.

I will never buy a product with syscooling teamed up with it ever again.
