BITMAIN‘s Liquid Cooled Miner C1: It is not only cool, but it is cool

[dogie]

Well, if C1 price is 1 BTC then I would like to buy S4 for 2-2.2 BTC. Bitmain?.. My coupon will burn out soon and I can't use it to buy an expensive S4...

One includes a PSU one doesnt.

[dogie]

Since Bitmain is selling these without matching hardware, it would actually be really handy if they could make flowrate vs pressure drop chart for them, similar to the one in this datasheet.

You don't happen to have a flow meter and manometer, do you?

And variable speed pump, no

Heh, send me one and I'll test it for you.

Sure, just fill out your details on bitmaintech.com and send a bitcoin payment

Unlikely to ROI and you seem to have to build half of it yourself

pass.

@ Bitmain:

With the broken promises of updated firmware for S2 users & all the problems with the S4, PSU, firmware, etc, etc - I would like to see some proof that these will actually work as advertised before deciding to buy some or not.

1) Can you post a screen of one actually mining showing hash/error rate?

2) Will these work with all pools, including p2pool, or just a select few as with the S4?

3) Has the firmware been thoroughly tested this time?

4) What version of cgminer is bundled with it?

Thanks.

@ Bitmain: Pretty please?

Don't think that is too hard to do. Do they have some of them fabbed and running yet?

What would be the requirements to show a pass for #3?

Hmm i wonder if the C1 could run without the liquid kit.. there is still one fan there.. what if adding another one?

It will be bad idea.

This is really ridiculous here donate 1 BTC and built it yourself, unprofesional Bitmain......

They should include at least tubes and connectors but anyway too much hassle with watercooling.
Also shipping price (to Russia) kills the deal: 0.443 BTC for 1 piece!

[Rabinovitch]

I would like to buy this, just out of curiosity, if only I could use S2 buyer's coupon...

Aww, that sucks. Will it cost the same if u order 2?

You can use distilled water or Deionized water 。

You dont want to mine anyway, Putin will cut your dicks off

C1 water cooling kit already includes pipes, fittings and so on. Liquid with distilled or deionized water. The EMS shipping 60 $.

[lowbander80]

Les assume a faulty connection or a loose one.Fluids running and floating
 

Question

Would you place this miner in the same place together with
other equipment and electricity

But nice to think of home miners again
Its sure the first and others will follow

nice first step!!!

The S4 is more than just 2TH of hashing power. Its got an LCD (+0.05BTC), larger case(+0.1BTC), and a 1400W PSU(+0.8BTC).

That said, its overpriced and $1100/2.8BTC would be a fair price for it

he is talking about operating the C1 without any liquid cooling setup, with the hopes that a singluar fan will magically cool the device. It wont.

One of the biggest concerns I have, and one nobody is mentioning, is the mixing of metals.  These appear to be cooled with aluminum waterblocks, but people who already have decent watercooling gear (the majority of the people who will buy this) likely have rads with copper cores.  I have always been told to NEVER mix the two in a loop without the use of special corrosion inhibitors and/or specialized coolants.  Otherwise, you're basically creating a battery in your loop with different electric potentials... ionization... some chemistry BS that can damage your blocks/rads.  I assume that's why Bitmain says to use specialized coolant.  Which isn't a huge deal.  You can get a droplet bottle of  corrosion inhibitor that will last longer than the C1's profitability for pretty cheap at most WCing retailers.

Bobsag, since you're familiar with WCing, what are your thoughts here?  Is this something that people need to be aware of or has the "mixing metals" thing become just a dated myth now?

As far as I know, nature hasn't repealed galvanic corrosion. If you're going to run copper gear with aluminum you'll absolutely want a corrosion inhibitor in there.

What Mr Teal said.
I havent had to use alum block in forever... copper is better and does not have the same corrosion problems. This is a certain deal killer for me.
