no more c1???

The large tank pump has arrived from China but the other two pumps have been moving water with no loss for quite some time so I won't disturb the setup. My two C1's are running at 37/39/37/38° & 36/40/38/40° so I like water cooling. These board are the same as the S3+'s if I'm not mistaken but well cooled so capable of higher hashrate? I'm running my C1's 243.75M/00675v/981GH/s for lower current on the line. One S3+ is running at 42/39° and the other with a single board is 39°. The one with the single board had started to heat up so I removed a cheesecloth filter dropping the temps down from mid-50° to the 40°'s but perhaps the damage had already been done. The next day one of its boards had failed. The higher temp meant higher current due to increased inefficiency and some damage occurred. So, I like the water cooling. I'd like to put water blocks in the S3+'s.
You can buy the Water blocks..

but, remember the C1 also has the Air Cooled Heatsinks
email syscooling, I bet they make those also..
Nice. Thanks.
I see the ribbon cables will conflict if both board are orientated top up. Or one could buy two water blocks and only put a single board on each so as to have the distance.
Right, the cables would be a consideration.
Also, some earlier revision S3 boards have the data cable connector mounted
on the back side of the board.
The C1 boards are delivered with ribbon connectors all on the component side of the board.
Makes it easier to plug in ribbon cable if you have back to back boards mounted on a water block situation.
It's possible to twist the cable and squeeze it in between two boards on a C1 if you
have an older rev hashing board.. if, the cable will reach.

@bitmain
You update S5 but you never update C1, its like you want C1 to fail... why?

I don't think they want the C1 to fail, it's just that they have other things on plate. I imagine next gen is big focus right now.
And really I consider they already have changed C1 a lot on purchase. Now you get parts from Bitmain for a lot less then we paid. And they don't have to mess with going through Syscooling. So as far as hardware being offered that was a big plus in my eyes.
Only thing I wish they would do is switch syscooling pump with another pump. But I'm guessing they are a package deal with other gear.

Changed my mind when I considered the fan noise. The room has air exhausting via one window with radiators for C1's and another window with an exhaust fan for the 4 miners just inside. So a lot of fans. The room draws air from the rest of my place which causes a draft in the kitchen where the chicks are now sleeping but no worries, a warming pad underneath and a cover over the mesh. Couldn't hack the warming pad PIC, now they time out at an hour as heat can damage tissue, so whipped up a 55 minute timer and a solid state relay as cycling power to the heating pad resets its timer.
Found a use for the heat. My hens have been coming up short with eggs so I picked up a couple of sex-linked red hen chicks this morning and the two are in a cage on my kitchen table crying missing their flock. At night they'll be moved into the miner room. Nice and warm.
Please take pictures! This sounds like the first time it's been used for this. It sounds like a good idea and not a fortune to do like some ideas others used as warming pool, hot water, etc where it as not practical. Yours sounds like a winner.
I want a picture too. This can be the cutest miner photo ever.

Cannot change mining pools in settings. Any advice?
1) ssh in
2) run the command 'screen -r'
3) type P and that will take you to the Pools screen (took multiple P entries to get it to the Pool Management screen)
4) Then one could usually enter pool information but I see on mine the cgminer notification messages scroll down the page, e.g. Invalid Bitmain-voltage
So, this method won't work.

last resort is always ssh. edit with "vi /config/cgminer.conf" and then run "/etc/init.d/cgminer.sh restart"
but don't do this unless you know what you are doing.
Or last resort flash the sd card in it. That is one thing I love about S4 and C1's is their use of sd cards.
Makes it a lot harder to brick completely.

Can you take a screenshot of the settings? What is happening when you are trying to change pools?

So, the z750 supplies work under heavy load. Typically a computer supply will claim a certain wattage capability and on the side list the current available on each voltage but don't supply that total wattage to any one voltage.
In switched mode, the z750 has a single rail 12v @ 62.4A which equates to 748.8W. In standby mode it is 3.3v @ 5.5A which equates to 18.15W
Okay I was looking at this as it seems to be similar:
Abstract from google listing: COMPAQ PS4060 750W. HOT SWAP POWER SUPPLY. + 385V. 660uF. 100-240Vac controller. Primary board. 3.3V/ 40A. 12V/ 25A. ML4824-1. PFC / PWM ..

-------------------------
Are you sure the single 12v rail is suppose to supply 62.4A? Are there other voltages?
I stand corrected. I picked up my Dell N750P-S0 today and it clearly states12VDC 62.4A and 3.3VDC=5.5A.
---------------------
Have it powered up and seeing 12.20vdc!
---------------------
Connecting to the new supply - I could solder here but the lower flat washer makes contact with all three connections: https://drive.google.com/file/d/0B_DLmNkCkkVpcjc4ZUduYmM3dUE/view?usp=sharing
--------------------
Tested an older miner the other day and it was 368 watts/281GH/s @ 12.0vdc with 2 of my cheap supplies (<$25 ea).
Am running the N750P-S0 to the same miner, 372 watts/285GH/s @12.2vdc ($17.96 w/free shipping).
Told you they were great power supplies for the money. You can buy them dirt cheap, I'm just lazy and use a breakout board with 16AWG PCI-E cables on mine.

Thats a neat solution! Are those poles rated to carry that much amperage? (they look thick enough to me, but just asking)
And the server supplies should be more robust .... happy mining!
