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

[RchGrav]

I will wait until B1 ships before making a decision.

I ordered one last night just for the heck of it.. because my one friend was into ordering one.. so I said order one for me also.

Total was 1.3722  BTC for everything* incl accessories... if you do the math its almost exactly the same as 2x S3+ at current pricing when you take shipping into account.

I'm planning on using a .999 Silver Kill Coil ($6.99) and DI Water.

I built a liquid cooled PC years ago, and I swore NEVER AGAIN.. just too much of a pain in the ass to maintain.  Oh well..

*I reimbursed friend for the order in 100% BTC even though the accessories were paid via a different method by him.

Please don't, you've just ordered a copper radiator with an aluminium block, right?

I don't believe so.  I ordered the recommended accessories linked from Bitmains Website from http://shop.syscooling.com/goods-45.html

Radiator	AT360 Aluminum Radiator
Material	Aluminum

Should I not use the silver + aluminum and go another way?

Was hoping to make the setup as trouble free as possible.

Liquid Cooling Sucks.. lol

They better not send a copper radiator!!

Do you still see any issues with my cooling liquids and additives?

It says aluminium but most radiators of this formfactor use copper channels internally so you can never be sure. The barbs are also [strangely] listing as having copper, so I wouldn't risk it.

Ugh.. WTF..  I looked at the specs of the recommended accessories linked from Bitmain, saw the word "Aluminum" and said great... I'm set.  Why would I assume they would be offering proper accessories?!.

If I can't use silver, can you even use DI with the proper additive? PT Nuke, something else?  I would think the DI is the most reactive liquid possible to use since it is stripped of mineral ions.

What is the BEST thing to use with the lowest amount of maintenance?

PT Nuke [which was replaced by PM Nuke wasnt it?] is just a biocide, its not going to stop the water corroding. Your best bet, as recommended is to get a premix coolant. Yes it costs $10 a litre, but its $10 rather than potentially having to replace $100 of components.

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

Yeah, 850-900W

oh? Thanks

this is the radiator bitmain suggested - i doubt it contains copper (more expensie than aluminum anyways) in contact with the fluid

As I said, you can never be sure until you receive it as its pretty standard to coat the internal chambers with copper. What about the fittings listed as copper [again, probably coated]?

[BitcoinRuinedMyLife]

oh hooray!!

yet another shoddy, overpriced rig from bitmain....

such surprise, etc

Yeah, I am wondering what frequency these are clocked at so we know if there is any headroom at all.

Do think a 850w gold power supply rated at 70A on 12v will be able to handle the C1? I know it will run at 100% capacity but I have  no use for it otherwise.

cutting it REALLY close - good chance you'll have to underclock in order to run stable, especially if the coolant pump draws an extra ~20w. IMO get a 1000W PSU and youll be fine, and your efficiency will be a bit better (most gold PSUs are ~91% efficient at 80% load, but only ~85% efficient at 100% load)

[buysolar]

More S1 upgrade kits please!

[RealMalatesta]

I think it will not be a problem to run three C1s with one strong pump... will give it a try :-)

[wilth1]

Is it possible to just buy the boards for the C1?

Your efficiency will be shot. Add 20% more watts to stay around 80%.

With the super cheap kits being sold I'm not sure there is a reason to. Removes all your redundancy with no benefit.

I agree. However, I still have a lot of old stuff here in my basement, so I'll only have to buy some fittings and new tubes. Especially with a 9-fan-radiator and a 1800l/h-pump, I guess it should be possible. In the worst case, one miner will be super-cool while the middle will be warm and the third one overheated...

What are these chips clocked with to begin with?

Heh, we have a company we contract for that has a couple Techniwell TW700s sitting idle. I wonder how many one of those could run?

[Experience101]

So if i may ask; whats the required wattage to run a single C1 without over clocking it and whats required to overclock it. Please and thank you..

As i said many pages ago, RUN THEM PARALLEL, god damn you noobs (also since the block channels are quite small 6mm, make a cheap manifold - 1/2" to 3 x 6mm tubing)
