Making watercooled S7 (NOT a guide. I wish I coud, just brainstorming)

[SunnyIgor]

So far we have had  C1 waterblocks and syscooling waterblocks wich are identical voor S1,S3,S5.

Noise is my biggeste issue, so i ame loving the sound of my pump en fans for the couple of radiators in my loop.

As fare I undersrand S5+ and s7 hashboard are different from s1 s3 s5 boards

My question is are the old c1 or syscooling blocks enoug to cool the s5+ and s7 boards?

And if not will there be a s5+ s7 waterblock?

Can some communety member make it, should syscooling do it.... as there waterblocks are fine!

If it will not be possible for s7 to be watercooled i have to sell/trade for s5'5

Because my hole farm will be watercooled or at leat not realy hearable.

I also made an extreme "bong cooler" aka tower cooler so i can push the miners harder.

Looking for expert advice, maby some of you tried it on s5+ boards allready?

Thanks for looking and or replying!

Well for starters, i don't think anything can be planned until we know the exact length of the S7 PCB/which area need to be covered. After that we just need to find a watercooled heatsink that can fill that area and dissipate 150-200w.

So i'll put the thread on watch and see if we can get more information before we get started.

whe should ask syscooling to order or sample 1 board en let them make waterblocks.
btw i emailing them right now

Thats a good idea but they will probably raise the same question as me. Nor will they want to front 2k to check it out. Regardless it's not possible to get them just yet. Sending a email to Bitmain requesting the dimension needed of the heatsink may prove more productive if you which to shave off some time before the S7 get shipped.

I don't really understand your technical concern (not that smart ). So manby best if you contact bitman.

Some S7 allready in the wild! maby he can anser your question?
He seems very helpfull and open about it!

Time to answer some questions!

Can you try to run it with two PCIe connectors per board? It would be interesting to see if it needs all three.

The miner won't operate with two PCI-e connectors per board, according to Bitmain. See this image: https://i.imgur.com/OV3f8Ql.jpg - Read point #1

Thanks in advance for the sneak peek!

Can you confirm that the controller has 9 18-pin jacks, the same as the S5+? There are a number of us interested in trying to control multiple S7s from a single S7 controller.

I assume that it's the same controller, given the pictures from Bitmain. But it would be nice to have actual confirmation from someone with an S7 in hand.

Also, how long are the controller ribbon cables? Any chance that they would reach to an adjacent S7 next to a center unit?

Note that there's there's already a separate thread around obtaining extra or longer ribbon cables:

https://bitcointalk.org/index.php?topic=1173573.0

Confirming that the controller has 9x 18 pin connectors. See this image: https://i.imgur.com/JzUJsN9.jpg (just zoom into the connector area, the image is pretty high resolutions so you can count all nine)

As for the ribbon cables, they look fairly short. I don't think you'd be able to reach an adjacent S7 with the included cables. But I'm sure some longer ribbon cables would be able to reach the controller from a foot or two away.

How is your power setup for the G1600 on the S7 each blade on its own 12v rail ? (For others reading this the lepa has 6 12v rails which makes this a little tricky set up)

I mentioned my power configuration before:

I'm using the GPU/CPU/RAM rails on the LEPA to power the unit. I have four PCI-e connections on rail 12V5 (three connectors powering hashing boards and one powering the controller) and two connections on each of 12V3,12V4 and 12V6. So in total there are 10 PCI-e connectors on the miner and that's how I split them up.

I took a video of the unit as well, just going to render it and upload it now. Should be up in less than an hour! (Slow internet ftw!)


Some images I took of the miner for those interested:

Syscooling has not logged into this site in months I think they are not coming back at this point.  Twords end of relationship you could order from bitmain and not mess with their site.

I think all bitmain will be fan based from this point.  It just is easier on them when you think about putting in data centers till they sell.    

This means chances are it is going to be mod's from this point on.  Which I'm sure will happen.  There have been some nicely done S5 mods.

Ah i see. If some people already have S7's in hand, you just need the dimension of the PCB, this way you can know what size of heatsink you will need. You may also need to know where the holes for the screws are. Then all that is left is getting the needed parts (Screws, tools, heatsink, tube, pump, liquid) to assemble it.

From the images on the bitmaintech site https://bitmaintech.com/productDetail.htm?pid=00020150827084021471OHYdwd9D06A0 there don't seem to be any screw holes. They might have the blades just settled in a groove like they Spondoolies did with their SP20 Jackson design. I would love to disassemble an S7 and do a mockup in Inventor for some water cooling fun.

[VirosaGITS]

Are you sure the 4 brass-orange colors small circles in each corners arent screw holes? IF not then that could be possible but unusual for Bitmain's designs. Worse case scenario you would just have to drill holes in the Heatsink or even PCB where there are no circuitry. Please correct me if i'm wrong but there would probably be no issues there?

Those look to be copper pads. From the available pictures it looks like the boards are supported in grooves top & bottom?

S7  body without FANS  is about 224 mm long.

S5+  body without FANS  is  192 mm long

S5+ blade is 182 mm lomg, height 125 mm . 

Height including connectors 140 mm, higher length connectors side is 67mm long.

S7 blade is 214 mm long?

S7 blade height is 125mm.

I can't tell from the picture, it would have to be confirmed with bitmaintech or have a sample blade.

The PCB is probably multilayer, more than top and bottom, Bitmaintech would have to supply with information where it would be ok to drill any holes.

You do not need holes. What  needed is a  Arctic Silver Premium Silver Thermal Adhesive Glue .

[mavericklm]

if the hight of the asics, on the blade, is under the hight of other components things get more complicated

also the size of the blade might be different from the c1 blade........ some more complications

[RichBC]

Not sure that I would use an Thermal Adhesive? It's one thing to remove individual heatsinks but removing an entire board stuck to a water cooled heatsink is verging on the impossible. Also I have always avoided the silver based compounds because of the risk of getting some onto the pins of the chips.

s 3 boards are 301mm(L)*123mm(W)*155mm(H) minus fans and case.

so 1 s3 / 5 board lenght shoud be 301-( 2x 25) for the fans i am not sure, could be more or less.
251mm  making it shroter then s7 board
which seems no problem for me.

I think i will just order syscoolling kit and give it a try, if it fails I make 4 s5's watercooled

btw all I care about is watercooled S& not S5+

I still don;t have my s7 so no news, maby someone allready made s7 watercooled?
Or tried to do so and horrebly failed, please all info is welkom
