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

[dogie]

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? 

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.

* Coolant: If you choose an aluminum radiator, you can use deionized water with an additive, or specialist coolant. If you buy a copper radiator, you must only use specialist coolant.

The link for the "ANT C1 mining cooling kit" is working now.  $40 for shipping to the US?  Is that correct?   I only see one shipping option.

Yes, and about $15 for adding a second kit.

Actually, it's $24 shipping for 2nd kit.  I decided to order 2.  I'll either buy a 2nd C1, or sell the 2nd water cooling kit.

Sigh, my reserved post was deleted, need to wait for Theymos to come on now to restore it. For now here are the links:

What you need to get started:

____________________________	_________________	______________________________
1KW PSU + ethernet cable	[amazon.com]	| $152.19 + $0
Special C1 watercooling kit	[syscooling.com]	| $50 + ~$50
1L* of coolant	[aquatuning.us]	| $7.29 + $8

*Get 2L if you think you might spill or want spare.
*^Optional but highly recommended.
^%No additional shipping charge if purchased with the coolant.

On coolant how much do you need for each C1?

It's in the list.    1L (1 liter)

1L will do one kit easily. At 6mm ID you could get 35m of tubing out of it. But -150ml for the resevoir and about 250ml in the radiator. tldr, you'll use 600ml or so, potentially more if you use longer tubing.

[Rabinovitch]

One includes a PSU one doesnt.

I don't need S4s PSU. ) ATX or server PSU bought at local market is always better (especially if I can put it inside the miner case...).

So, the Quick Disconnects are really added to easily separate the pump from the radiator, right?

I've never dealt with a pump/radiator assembly like this before, to fill the entire system then, is
that done through the top opening in the pump? or some other method..

Thanks

[Rabinovitch]

Personally I would like to fasten the radiator, pump and whatever else at the top of C1 using some kind of installation rail, for example, from meccano. 
In this scenario you will no need to often disconnect something...

[charles2k]

Good idea, but incl. all accessories and shipping overpriced. Especially for people in Europe, which have to pay 19-22% VAT.

[Kimowa]

S2 seems like a better deal as compare to this and you can use coupon too..

[toptek]

This is interesting, but I would be more interested in buying more S1 upgrade kits.

Or C1 upgrade kits . sense it the same thing as a S3 So I'm guessing why not just sell them as C1 upgrade kits  for S1, it looks like it would would work .
 


extend the S1s just a tad longer  ) .

the Quick Disconnect are not added in the water cooling kit,but G1/8-8 Tubing Adapter is included.as you say, the entire system is filled with coolant through the top opening in the pump.

Electricity rates make it viable in the EC?

Just wondering if anything is viable unless it is made locally in the EC this is true over everything that is being made today given the BTC price.

Do you mean S4? 

[Soros Shorts]

Not to spread anti-environmentalism, but an obvious great market for this is people who have unmetered water.

That's the other side of the C1 - those who use large farm evapourative cooling can simply plumb in the C1 into their mains.

Would swimming pool water corrode the water blocks?

[PatMan]

@ 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.

Again.....

Would probably deposit a load of minerals in the blocks and gunk up everything. Maybe though, interesting.

What is the watt in total ? Watercooling and the c1 in one psu? 850w?
