   Components include cover,waterblock and fans,you could order 8 hash boards from Bitmain,and assemble a watercooling S5 miner by yourself.

What other components are you providing to cool the roughly ~2KW? Same as C1 kit?

Thank you for the cool project and experiment!

If you could, please mention   that any hardware modification will void Bitmain Warranty Qualification, if you could....



But,  what about the 4 data cables and 1x 4 pin power cables for controller board? They need to do a longer or replace it.

http://perearstike.ee/S5/IMG_0008.JPG

1 controller receives only signal from 4 hash boards. Do I need for this projekt  two controllers ?

I think so, the divider looks like you can attach a controller card to each side.  I just don't get why it looks like there are 4 Ethernet openings between the fans (looks like they've upgraded to 140mm fans).  I'm also curious what type of cooling kit will be offered?  I don't think the C1 cooling kit will be enough to cool it.  Or will it be the big kit and that will be enough to cool 2 of these?

EDIT:  I see now, 4 controller cards (do the other ports not work on the S5 controller card then, shouldn't you only need 2 of these with 4 S5's?), 2 on each side of the divider, equal to 4 S5's (8 blades/boards) or that was the original design, so yes it's probably one of the big radiator kits for each of these since it's 2400 watts.

  Today I received   SC-BC2 antiminner cooling kit   http://shop.syscooling.com/goods.php?id=46
He has a huge and quiet.

One controller card works for me with 2 Antminer S5 ( together 4 blades )

Looks like this will need at least two 1300 G2 power supply, using all the PCIe connectors (4 single + 2 double connectors = 8 ) that come with it, on each side.  With 2x 1600w power supply you may be able to add an additional S5 to the setup (=1200w x2 + 600w = 3000w), but will need to purchase a couple of extra PCIe single connector cables per power supply if you want to add the additional S5, by the way the T2 Titanium has been released).  Hopefully it'll be enough to power the 8 additional fans and the pump also.  Would have preferred the controller cards at the top with just 1 per side (=2) like the current S5, if it needed 4 then one facing each direction (front and back) may have been better if the lower board was slightly shorter and only half the length of the S5.  I'm estimating that the kit and additional S2 big radiator kit will be about $300 plus shipping (4 watercooling blocks = @$100, cooling kit $120, enclosure, cables and 2 fans =@$60).

Are these the same watercooling blocks that fit the S3/C1's with just a different screw hole location on one side of the watercooling block?

This is an amazing mod!

If anyone got one of these up & running can u please let me know??

ANTS3 Water block   http://shop.syscooling.com/goods.php?id=47

Today I received  4 pc. Screw holes location  on both sides  and it  is compatible with the  S5 hash boards.

Is there screw holes for both the S5 and the S3 on each side?  The C1 has screw holes so that one board is facing upside down from the other, while the new kit shows the S5 boards both upright?

One side has a total of 20 screw holes. Exactly the same spot where the S5 20x screw  holes is.

C1 uses S3+ boards, only the data connector is soldered to the other side of the boards. The same 20x screw holes.

How is the noise of these things?
I have 4 s5's with s3 fans on both sides, but it is still to loud for my girlfriend.
Maby I can make them watercooled, I want to run them at 350 or 375.

OK, if the kit is reasonable, then I'll order a kit, but know that the shipping is really high to the U.S. (the big radiator kit along was more for shipping than the $120 price).  I'd be interested to see if it can cool the 4 S5's enough to run them at 412.5M constantly (that should be about 1400w per side, so two 1600w power supplies should work well, that would be about, = about 1,350Gh/s x2 per side = 5,400GH/s)?

If that is like a 2*c1 side by side, why not make 3*c1 side by side, also 1*c1 but with s5 blades, c2?!

Also: it should be only 1 controller for al boards
         use 14cm fans! not the screaming 12cm from s5

From 1 x C1 boards+ controller and 2 x S5 leftover  parts I built air-cooled C1. In the same style as the S5 . The two pieces side by side, and only one has controller.

How about some kit for ant s4?

This would be a lot more attractive if Bitmain would ship bare boards.

You will also need the cables, screws  and springs.

Screws and springs are easy enough to source, though they could include them. I would envision the cables being included in a kit consisting of a BBB, the controller board, four hashing boards and the needed cables. It's nonsensical to purchase the aircooling heatsinks, fans, extra controller and plastic bits just to ship all that weight across the world and then strip it down and throw it away. :P

C1 kit is OK,but both sides of radiator need to be installed fans.1 C1 kit could support 4 hash boards,the whole miner need two kits.

Your advice is appreciated.Untill now we extend cables ourselves,and trying to find longer cables in market or find a factory for custom-made cables.Later I will provide solution.

Yes you need to order two contollers.

Actually 2 of 4 Ethernet openings will be used,previous controller could only support two hash boards,but now hardware have updated,every controller could support four.We just consider that some people already have S5,and want to modify it to watercooling,and we prepare 4 Ethernet openings in case that their hardware couldn't update.
C1 watercooling kits could be used.Both sides need to be installed fans,and this modified miner need two kits.

BC2 kit is really strong,especially for those who have multiple miners like you. ;)

How about water distributors?  These are not included in this ANT BC1 mining cooling kit . http://shop.syscooling.com/goods.php?id=45

EDIT. Got it. What is needed is a set of two ANT BC1 mining cooling kit.

Each hash board is about 295w,I think one 1300w power supply could only support 3 boards.I am using 3 1000w power supply to support 5 boards.
The waterblock is the same as C1's.

I am running 5 boards with these components,but I couldn't find somewhere to upload picture,later I will show you.

When are you expecting to have this for sale and when will you have an answer for the longer cables?

Much more quiet than air cooled S5,that's exactly why we do these things.

Bitmain works on developing miners,and we work on how to modify miners to provide better experience .;)If you want to assemble "C2",we might some day show it to you!
The fan is 120mm,1 controller could just support 4 hash boards.

Just to confirm, that's not an 'official' / rumour of an 'official' C2. Its just Syscooling's kit's name.

The problem with kits is they require more work than miners! A full miner has to be built [heatsinks, case, fan etc] to quality test the hashing boards - the same as a normal unit. But they then have to be disassembled and cleaned in order to be sold as board only kits. That's time consuming = more expensive / not as cost efficient as one might imagine.

How do you know we are testing S4 modified kits? ;D Not long,don't be hurry.

Yes they will do.

In a modified S5,you need to purchase 8 boards,2 controllers,screws,and cables of appropriate length(about 17cm,when sure I will post here).

You could purchase appropriate cables from Bitmain,2 are about 10cm(default length),6 are 16cm.
Right now I just post a thread here to show you about it,and take advice from you genius men,not long it will appear at Syscooling online shop.

Include two distributors of this type.
http://www.syscooling.com/uploads/photo/3tong.jpg
Need two BC1 kits and 6 extra fans.

:D Its not Syscooling's name,just copy from smart man's idea.

Exactly.But if users could assemble by self and make no mistake,it will save a lot.

We can assemble it by our selves, but  will the final price be worth it?!?!?!

Waiting for bitmain to post prices on the kit(4blades, 1controler&bbb board and the rest)

That's one way of doing it, but it's pretty inefficient.
Building a test jig to cycle through boards would be relatively trivial and quite cheap though. For something like the S5 boards you just need a flat heatsink on the bottom with some pin guides to align the boards. Slide the board in, attach a PCIe connector and the data cable, and push a button. A small air piston pushes the top plate down which provides pressure to the back of each chip, barcode scanner logs the serial number and the attached controller runs a known test data set that allows you to characterize and record the true error rate.

Test jigs are pretty standard in electronics manufacturing, and something simple like this that doesn't require fancy network connected instruments could be made for a few hundred bucks each if you build a dozen or so. Build twenty and a few workers could pump out 1000 boards in a 12 hour shift.

Hopefully they'll offer a kit with the big radiator also, as that would require less chance of leaks and less setup than using 2 or 4 smaller radiators, plus in warm locations I don't see how 2 of those little radiators are going to help remove 2400w of heat.

We set the price after comparing.It will save you money,whether you bought air-cooled S5 or complete water-cooled S5.

Two radiators that SC-BC1 watercooling kit includes are enough with each radiator installed 6 fans.SC-BC2 kit uses a big radiator,and noise is a little bigger,if you don't mind you could choose this kit.

Would it be possible to add waterblocks to the current S5 case?  Are the attachment points the same?  If I just removed the rear fan, could I just add waterblocks to the boards?  Knowing I have to disassemble all, but could it fit and keep the controller card on the top?

You will still need a fan with water cooling. A quieter one hopefully.

Oops, forgot it only comes with a front fan, was mixing it up with the S3 in front of me.  So, will the water blocks fit with the screws that hold them in place on the S5?

No. Because there is no housing. There are only two pieces of plastic and the two ends, exactly the same as in S3

Will bitmain do some ??  ;D

So one needs both things below:
http://shop.syscooling.com/goods.php?id=51

and

http://shop.syscooling.com/goods.php?id=45

in order to get the whole system going.

You need two of the radiator kits, or one of the large kit.  But, the case doesn't seem to list the needed extra length cables yet.

back in the thread it said you need 6 fans instead of 3 with the small radiator

How much are the S5 hashing boards and how do you go about ordering?

That's right, the kit will need 3 extra fans per radiator.  Also, there was mention about screws and springs also.  I wonder if you buy the boards, maybe the cables, screws and springs are included from Bitmaiin?

Don't forget the 2 controller cards also.

I costed shipping for two units without rads, and it came out to $437US with paypal.  No bitcoin?
wayyy to expensive.

Air-cooled S5 doesn't have screw holes to hold waterblocks.

I don't think so,but you could ask Dogie.

You could purchase appropriate cable from Bitmain,8cm*2,and 16cm*6.Don't forget purchase 3 more fans for each radiator. ;)

You could ask Bitmain about boards,and we think it is cheaper that you assemble a water-cooled S5 rather than air-cooled S5.

Exactly,all you mentioned need you purchase from Bitmain,and we will also provide some other type screws for modify requirement.

Shipping cost is unavoidable,and value of bitcoin is changing all the time,sorry about that.

Screws arrived,purchase could be accepted http://shop.syscooling.com/goods.php?id=51

Remember,when you purchase hash board from Bitmain,you also need buy 2 controllers,screws,springs,cables(8cm*2,16cm*6).If you want or need to extend cables yourself,please tell us anyway,we could provide you cables and heat shrink tubing that you need for welding.

Our modified kit includes:case,4 waterblocks,2 fans,2 fan covers,screws,heat conducting paste,2 distributors,cables and heat shrink tubing(if needed).

You can take bottom of  S3 and drill   into 8 extra holes. Bottom  is not necessary for working the S3
http://www.perearstike.ee/C1/IMG_0035.JPG
http://www.perearstike.ee/C1/IMG_0031.JPG

Also, you have to drill 4 more holes

http://www.perearstike.ee/C1/IMG_0032.JPG

So I am confused.  Is Bitmain on board with this or do we have to lobby them to sell us what we need?

Good question, guess when we see on their site that you can order the boards by themselves with the accessories, we'll know for sure.

Bitmain should sell a watercooled BM1384. I pledge to buy for 3T/s if they sell one.

Unofficial for now, and no kits at this second. Have passed it on though so its a maybe^{soon TM} :P

Thanks for posting this, it answers what I had in mind and want to do.

As Dogie said,it is unofficial on Bitmain now,but we could provide water-cooled S5 sale,price is $18 more expensive than official price of air-cooled S5.In addition,because we purchase boards from Bitmain,amounts couldn't be too small,if you want to purchase water-cooled S5,amouts of each order is 3 at least.You could send email to  watercooling@ysun.net   for purchasing,and preparing time of arranging shipment is about 1 week.

But to fill out the case you show in the OP you would need the equivelent of 4x S5's correct?

You are selling a beast 8 S5 blades like the case in the OP or a 2 blades watercooled S5?

I don't get it.  What if someone orders 5 then?  You'll get 2 partially filled cases?  One with 2 and one with 3 S5's in it?  Or one filled with 4 and then one mostly empty with just 1 S5 in it?

That's right.

As you can see,1 water-cooled S5 have 4 waterblocks,so it is equivalent to 4 air-cooled S5's.

Ok,I don't introduce it clearly,forgive me  ;).I said 3 S5,it is water-cooled S5,equivalent to 12 air-cooled S5.The price is $1307 each water-cooled S5.I know that is unconvenient,I will post a group-buying thread to count how many people want to purchase.If required amounts of water-cooled S5 is more than 50,the price might be a little lower.

Water-cooled S5 group-buying thread https://bitcointalk.org/index.php?topic=936343.new#new

Tupsu, you stated that water blocks need to be attached to the bottom plate that you drilled 4 holes in, but is this really necessary?  Isn't the 4 screws on the front frame (behind where the fan is attached) enough to support it?  The back would be supported by the tube connecting the two water blocks together.

I have built water blocks  in C1 housing .  There are four mounting holes on the bottom for water blocks and four mounting holes in front and rear. Screws are very short, so I used  all the screw holes.

 Because  Syscooling   has not yet been posted my S5 Modified Kit , I made today  another  C1 double housing for my ordered 3 x S5.


S3 housing construction with 2 water blocks  is one possibility, but I prefer the C1 case  and even better S5 Modified Kit from Syscooling.

Sorry,gentlemen, I am so sorry that we couldn't provide water-cooled S5 business.

As you can see in Bitmain website,with the rising of bitcoin,the price of water-cooled S5 rise,too.And if we go on doing water-cooled S5 business,the price would be risen to $1633,that's too expensive.Unfortunately,lead time is about 1 week,shipping time is about 1 week,nobody knows how will the value of bitcoin be and how much will watercooled S5 be in 2 weeks,for you and for us,we both couldn't take this risk.

So,I am so sorry again to say that we still only provide modified kits,and you could modify air-cooled S5 to water-cooled.As far as I know,if you purchase large amount of hash boards,Bitmain will do this business.They disassemble boards from miner,if you order too little,it is not convenient.But what amount is large enough,I don't know,you could ask if you are intersted.

 >:( :( :'( Damn!!! >:( :( :'( Damn!!! >:( :( :'( Damn!!! >:( :( :'( Damn!!!

That's so unpleasant I know,everything changes too fastly,we couldn't forsee :'(

I don't know why bitmain doesn't sell us the upgrade kits for s1's and water cooled systems? What is the big deal. In this thread alone I saw people wanting to order over a 100 boards. Bitmaintech needs to decide whether they are miners or mining hardware dealers, because at this point they are just ticking off potential customers, driving away business and hurting their brand image.

http://files.g4tv.com/ImageDb3/268753_S/laziness.jpg

making a c2 would be the right thing to do with the s5 noise. imagine a single case with 3*c2(~7th/s) with inside pump and a long single pipe in pipe going to a big ass radiator, that you can place wherever the fuck you want!

Maybe it is unconvenient for them to do so ::)

That's a good idea,but bitcoin value changes all the time,is it worthy of doing so?

For some yes, but for most ppl it is not worth :-[

Atm i'm looking for an electric boiler with coil for steam&hot water. This way i will not trow away the heat and have warm water(~40c) at the sink but also washing machines!

Yes I'm also planning on using the liquid cooled miners to heat the water in my hot water tank. One of these 8 board S5's running at 2400watts should be more than enough for the average family. I even installed a heat sink for dumping the excess heat when the hot water tank hits the right temperature. Once I dig in the pool, I'll be able to use them to heat the pool as well. Right now it's 9 degrees fahrenheit outside and my whole house is being heated to a very comfortable 72 degrees fahrenheit by air cooled miners in the basement radiating heat through the floors. By using the heat from the miners we get to radically extend their usable life cycle. Once I've completed my solar pv system my site will be 100% self sufficient, the only reason for me to swap out miners is due to hardware failure or to increase mining density per unit of energy consumed. This is why mega farm commercial operations have trouble competing with small home mining operations. However I do have quite a few wonderful dual purposing solutions for them that would substantially increase their profitability.       

Here's a question I've got still.  Tupsu, Why aren't you using the heatsinks that are placed on the other side of the boards from the waterblocks with the S5 boards?  Do they not fit?  The C1 has them on the both sides.  I thought at first the chips where just on the opposite (inside) on the S5, but after someone posted a pic. of one of his chips burned out on the S5 thread, it made me think that that's not the case and the chips could use the heatsinks in addition to the waterblocks.

I'm well on my way to making some final orders to create a 2700watt 5250Gh/s water cooled 8 blade (400M) set up.

My C1 are all Batch1.  Their WaterBlock is only 14 screw holes on one side. the screw hole on one side of C1 WaterBlock is missing
and  is not necessary for C1 blades . But I'm lazy to drill extra hole.

Syscooling  WaterBlock have 20 screw holes on one side. So there can be placed S5 blades on both sides of the waterblocks.

I like the C1 waterblock more. Look at the picture, why.

https://bitcointalk.org/index.php?topic=914354.msg10235730#msg10235730

I want to use this for my s5;

http://shop.syscooling.com/goods.php?id=47

It mentioned that there is a left and right side.... does this also apply for a s5?? Do  I need to drill new wholes?

what I actualy need are only the heatsinks from this kit. How can I order only the heatsinks?
http://shop.syscooling.com/goods.php?id=51



thanks,
sam

You  need  ANTS3 Water block    http://shop.syscooling.com/goods.php?id=47

why this unit have 2 fans on it?  Why are they needed if you use the watercooled heatsink?

http://shop.syscooling.com/goods.php?id=51

because u need to cool down the rest of the mining board components, not just the asics! maybe some redundancy too;)
 

The fans don't need to run as fast in comparison to an air cooled S5.

have anyone tryed yet? Is there any temp different when you check the S5 admin panel?

It also seems that the ASICs don't have an internal temp probe like CPUs and GPUs there is a LM57A sensor on the reverse of the board to monitor tempratures, the fan keeps this chip cool so honest throttle back your ASICs.

I have recently purchased one of these kits and put in a single S5, left it overnight on a de-ariation cycle, (pump timed to run for 30s on and 30s off for 8 hours) along with tilting and tipping the chassis to ensure all air has been removed.

I booted the miner up this morning and blade 1 was reporting 80c and blade 2 at 67c, the first blade is getting the least amount of airflow due to the position in the case so I am running my S5 as a single blade at the moment and have ordered some ramsinks to stick on the LM57A chip as per goxed advise.

At those temps my water temp is only 30c and the water block is cool to touch but the miner still throttles right back and sits down if I leave board 1 connected, I hope the ramsink will decrease the temperature readout and mean that I can run both blades without shutting down.



https://i.imgur.com/Mhua6Dy.jpg

https://i.imgur.com/edKqNHV.jpg

The above pictures show the chip that needs cooling down, the rest of the components don't really need too much cooling (apart from the ground pads/heatsink pads) on the backs of the ASICs but moderate airflow will be fine across those pads.



EDIT: This is my stats page with only one blade powered and the water at 30c

https://i.imgur.com/kvjjlql.png

I have just ordered 10x watercooling heatsinks ;D

I will keep you guys updated ;)

why did you de-ariation cycle, (pump timed to run for 30s on and 30s off for 8 hours) ?

Is this how it should be done ? Sorry for the stupid question, is my first watercooling project.


Is the problem that the heatsink cant handle 2 boards on it? If you use only 1 board on each heatsink would it make it work ?



EDIT: Sorry I read your post again..... so the heatsink is cool.... its just the sensor that actualy reporting false temp making it to shutdown?

There are lots of ways to skin a fish but this is the way I chose as the pump I have has a de-ariatioon cycle built into it. Most people with PC watercooling will generally try to bleed the loop by running the pump for a period of time and then shutting it down and rocking the case. Stopping the pump causes the smaller bubbles to clump together and form a larger bubble that is easier to push through the system.



No but that would solve the problem, the two boards that are closest to the centre of the fan gets the most airflow hence the temps are less of a problem, the outer ones don't get enough airflow to keep the temp sensor cool enough.


Thats what I think it is because I'm pretty sure there is no air left in the system but will keep an eye on things for the next couple of days, also without the fans running the temp skyrockets on both boards to 80c and then shuts down.

I will report back in a couple of days after adding the ramsinks to the temp sensors.

any progres?

Yes the ramsyncs I purchased to put on the temp chip took the temp down from 70-80 c to 55-60c (its in an enclosed cabinet with fans pulling air out of the top.) Unfortunately that was short lived as the Western Power were doing something nearby and we had 3 power surges/brownouts within an hour and it has killed one of my hashing boards.

Lol not to sound rude but somethin about this sounds bad...ur gonna trick the miner into believing its running cooler then it actually is and u expect it to not die from the added stress of mining at a much higher temp?? Heat kills miners and i have seen this post multiple times when googling so i figured i should reply now since i have read it too many times now....if the temp sensor is faulty then u should replace it or shoot bitmain an email but dont run it with a heatsink faking the temp readings just so u can mine again....theres a reason that auto shutoff is set at 80 degrees...even if it doesnt actually work properly the temp is still listed so rethink where ur mining and i wouldnt sugest doin this to other miners. It might be y ur board died not surges. Sure its posible but it could have just crapped out after being run under stress for too long.


On a side note i got the huge rad kit and s5 kit syscooling sells. It cost me almost $500 and the company is a pack of liars for sure. They told me it was shipped after i had to ask and threaten multiple times to get some sort of update after mot hearing anything about my order. They said it was shipped and they will give me the tracking info later that day and 4 days later i still had no tracking so i emailed twice and finally got a reply with tracking and sure enough the label was just printed right before he replied so i was told it shipped and waited a week only to find out it wasnt shipped at all which explains y i was being ignored for 5 days before actually getting the number. How is that legit?? But whatever onto the rest.

I email them explaining my issue and they kept blaming the currier for this problem but fedex clearly said when the label was printed....its one thing to blame them after it was shipped but fedex doesnt pickup packages before printing labels and hold onto items for a week before buying the postage....and if they do its on them to verify that doesnt happen which they didnt do.

So i finally got the first kit which was the radiator and it was warped and bent. The fins were fine and it doesnt leak but it wasnt square at all. Also u cant mount fans on the back side like they say u can. Maybe im as dumb as a box of rocks but how is 1 leg for something so large stable?? They only give 1 leg to go onto one side of the radiator. 2 legs would be good and even better would be 4 legs so its a larger stable base to keep it from tipping over. Instead i have to find the sweet spot by sliding the leg up and down to tilt it forward or backwards to balance it and stop it from tipping over and even then its not stable. Its not a huge budget part either so y they went all jew on something so simple is beyond me.

The second box arrived 2 days later with the s5 kit. Immediately i noticed the case was poorly cut. It wasnt due to shipping it was due to their production processes and lack of quality control checks. The case was the biggest issue. If they got damaged during shipping the outside would be dented inwards....instead the case had dents that were facing outwards meaning they were there before the package was even sealed. I had to use body hammers to flatten it back out because the case didnt line up at all. The grill slots were bent as well and i had to spend about 2 hours pounding away to fix all this bullshit. I was pissed but luckily i was too tired to complain since i did this after i had gotten off work so i was ballz tired by the time i finished.

They gave plenty of tubing and shrink tubing which was nice. They also gave extra ribon cable which was another bonus even though i had my own already.

The next issues were with the waterblocks. 1 the waterblocks have 2 holes each that dont allow screws to go into them. They can start screwing in but not as far as they should so the spring sits losely on the top instead of providing the tension needed to push the board down onto the blocks. Ik this is a defect in the manufacturing because each block has this issue with the same 2 holes! Luckily i have taps and dies so i tapped out the 2 holes correcting their screwups. The second issue is the barbs on the blocks....they are too effin big! I had to heat and stretch the tubing a bit just to get it to slide over the barbs and even with that stretching it was hard as shit! I have blisters on my fingers from me trying to get it over the barbs. I had to take a tiny bit of oils to lube he bab up too. Not alot by ne means. Even with the tiny drop i spread around with my finger it tooks a ton of preasure just to get the tube over the initial barb. They should have tapped g1/4 holes in the blocks instead of adding barbs themselves. If they had tapped the holes the barbs would have been smooth like the chrome ones they provide and sliding tubing on those isnt easy but its night and day compaired to the blocks barbs. It should be tight ik that but this is too fricken tight. I shouldnt have blisters. This isnt my first water cooling setup either so please dont "noob" me lol.


Also on a side note i learned botmain chaged their controller card design. Luckily i had 4 of the same type but i found out 1 version has a 18 pin connector and one has a 16 pin connector. One controller is v1.3 and the other is v1.4. The 1.4 one has 2 extra pins so i had to take 1 miner off the block and replace it with the 5th miner i had because i had 3x v1.3 s5's and the 4th had a v1.4 board but i didnt notice the difference until it was already setup. And extending the cables was a pain in the ass for sure. Only 2 of the cables had to be extended so 1 per controller not including 1 4 pin connector since the other 4 pin connector was long enough because the controller plug was facing the right way but only on that side but extending the cables too me about an hour each so before i said bitmain mass ordered cables...i think i can change that now because they clearly changed from 18 pin connectors to 16 pin connectors so they should be able to sell longer cables to people like me instead of us having to extend them ourselves which is a painnnnnn!

These china based companies r pissin me off lately. For the money im payin i expect more from them but they r just gettin worse.

So are there any decent open-source PCB layouts for a BM1384 chip? What if we made a decent design and had it fabricated and built *in the US* from a manufacturer that actually does quality control?

I could see a market for a high-density water-cooled system (maybe including a heat pump) that can do something like hook up to a water heater (http://www.rheem.com/Products/tank_water_heaters/marathon/?)

Hi guys, I am reading this and I really would like to know more. I have two Antminer S5 that I would like to have 1 miner with 4 blades using the water cooling system.

In your vision, what are the benefits to use Water cooling system?

Thanks Marco

No benefits today.
S5 is history with prize today 0.321 BTC from S5
in hashnest https://www.hashnest.com/hash_currencies/24/trade_markets/19

Not even with energy?

What about an S7?

Thanks Marco

or dump the heat in the central heating system!

It does make it quiet but instead of going with water cooling S5 go with Avalon 4.1's.  If you need quiet they will do it with no modifications.  

Watercooling sounds great but I can say it truly is a pain to mess with compared to normal fan's.  Listen to videos of 4.1's they are about the most quiet stock miners with just underclocking. At least that I have used (I'm talking full miners like Dragon 1T or newer, not including stick miners).

if someone is interested, i got 2 ''c2'' for sale!

one with 4 blades, 2.3th; and another one with 1blade/1waterblock 1150gh as a normal s5
