At the moment I have only 1 c1 so i don't need to think about this too much, but they do make these,

you can compare it to the standard supply

In the end it's all about you local conditions on whether a single rig setup can handle 2 C1's if they are in a nice cold room and you rad's are getting nice cold air going through them possibly. Otherwise you will just run you C1's too hot and shorten their life.

You can also see that the pump in the multi rig kit is a by the looks of it 750 lph compared to 450 lph and over twice the head. Things are never as easy as it seems.

So no difficulty seeing air bubbles thru the clear tubing while getting the air out? 

Mine was suppose to arrive today but I screwed up and used my PO Box as a UPS shipping address.  It's out for delivery but will head back to the office after customer hours so am told I can't get it until tomorrow.

Was thinking of distilled water with food coloring but if the clear tubing stains that won't work well.

Doggie's guide it very helpful if you have no water cooling experience, make sure you pay attention to the water flow around your setup the guide has pictures just follow them.

I like having my cooling rig running from my psu not my C1 as I could run the pump and get the fluid sorted without any C1 issues.

As far as air bubbles go, the main thing is read the guide filling the pump res while holding it above the C1 and Rad means you can get a lot of air out at the start, then you just need to cycle the power a few times as the res can empty out into the rig as the air comes out. I think I refilled mine 4 times or so ( As i was using Distilled water its not that messy with proper fluid I would use a filler bottle).

Don't forget to rotate your rad, I rotated my C1 a few times to get some of the last bubbles out some were quite big.

Oh Doggie mentioned we should use PC cooling fluid as the Distilled water has issues over the long term. I am ordering that as I write this.

Oh and finally the air bubbles should end up in your res so as long and you rotate you main item's around, any air pockets will get back to the res/pump.

good luck
 

thanks for the info I will have a scan round for some decent water cooling liquid.

I received my C1 today, on reading Doggie's guide and the cooling system notes I received, I concluded that I didn't want to power the cooling rig directly from the C1,
I bought 3 Molex pentuim fan cables, two for the Radiator fans and one for the pump. Although the pump is a 4 pin unit when I checked with the supplied harness,
only two pin's are used to power the pump in the same wiring setup as a fan. So with a bit of care you can plug the 3 pin fan connector into the 4 pin pump connector.

Now I could setup and test the water cooling without the main  C1 being powered. After getting most of the air bubbles out and testing for leaks for a few hours,
I applied all the PCIE connectors and started the unit up. I nice surprise is that with the C1 I can connected from my adsl modem network view page on the hostname which I
couldn't do with my S3's.

So far hashing at 990 GH/S in stock setup and running temps of 41/42 across all blades, room temp is about 25 C.

I am impressed with the noise I was running 4 S3's in my office holy cow that was a little noisy.
I will need to go though most of this thread seeing what pumps people are switching to, as I am not real sure I will get a long run out of the stock unit.

Oh I didn't have any specific cooling liquid so I am using distilled water at the moment?

Also I am running a Coolmaster V1000 gold psu seem to have all the right connectors and big single rail required for a C1.

Yes my nicehash/westhash miners are really kicking out coin atm +1

So decided to upgrade my units to use the extranonce patch at westhash, step one was to upgrade you firmware, was using antminer_S320140826.bin moved to antminer_S320141126.bin, well had a great day trying to work out wtf happened to my units.

So glad this site is here, anyhow cut a long story short, tried most of the fix's suggested here to no avail and my unit were sleeping every 10-20 minutes in the end went back to original firmware, so far no issues. Great way to waste a Sunday afternoon.


Will look forward to the new firmware that works as it sure seemed better to browse with and keen to run some of those voltage frequency settings.

"From another thread i posted in, but it has relevance here,"

I just started S3 mining and went though similar PSU choice issues, in the end i went with 1:1      1 psu per 1 S3.

To give me some flexibility I went with a FSP Raider 750 Watt 80 plus Silver PSU, it has 4 6/8 pin pcie connectors so I can fill all the S3 power connectors,
apparently this allows you to overclock and keeps the unit slightly cooler per given freq.

Secondly, it has a common 12 V rail giving 60 amps which is more than enough for an S3 and allows the PSU to run at around 50% capacity which has an efficiency over 90%.

One thing I have noticed with some Gold modular psu's is they have multiple 12 V rails and may add up to 700-800 watts but only deliver 18 amps (per rail),
 if you power you S3 with one connector per side from a rail like this you are going to have trouble as an S3 needs 24-30 amps depending on who you read.

With lots of PSU's it does chew up more space and power points but you don't have a single point of failure and your not running your PSU at 90-100 % capacity.

Good luck with your PSU hunting.
