Waiting...

Agreed, If you guys want blocks to start Prototyping this, and documenting, I will offer blocks to a few of you @35/each  plus shipping after I get my Engineering sample this week.

I will accept BTC too

If you get the radiator to bolt or zip-tie (which would be easier)to the existing fan hole's on the rear and mount fans on that.Reservoir could be mounted on one of the front holes.If people where wondering silver coil is added in reservoir. Still unsure how 1 block works. But i assuming you take all four boards and mount onto both side of Alum. block probably through the denser bottom blocks This way you could still mount it to the case holes should still line up. In which case one board would be upside down. In that case you woul have to take hashboard and pinpoint screw to the aluminum block. One think i didn't consider is the clearance of top heatsinks which could be left in tack if they clear on bottom upside down(block mounted)  hashboards.

And Silver wont mix with Nickle coated stuff..

Right now the design is all 4 boards would mount to 1 central heat block, the block is Alum, and until i get my hands on it I am not sure how its going to mount I am taking an assumption the rear fans (or front) come off, the tube go there, and reuse the case.

The other idea was a double loop with 2 blocks one for each  set of chips.... strung like this -- Resivor->Pump->Block 1->Rad 1->Block 2-> Rad 2-  or something sadly bitmain isnt supporting it yet, so I am going to have to do some trail and error to get it up and running.

The problem is when mixing metals especially.  Lets say you use a aluminum blocks in miner and then a copper radiator.   

Using special coolant can help on corrosion, but I doubt they will mix.  There are those silver "kill coils" but I have not tried those yet.

I think it's recommended to use aluminum because copper is corrosive but i think this guy has a handle on that. What is the plan a pump with reservoir hooked to a radiator hooked to stock fans probably could get away with using just rear fans with radiator attached. Where you planning on placing the block? Does it replace the existing heat sinks up top? Or would it be the two main blocks that replace the bottom?

I would probably be interested in this are they aluminum or copper blocks. You dont want to mix dissimilar metals in a loop. Thanks

Look up galvanic corrosion water loop. Interesting reading

Currently.. No my best guess is $~45 once all is said and done for the blocks, MFG told me $30 per piece, and is sending me an engineering sample shortly, I am thinking if if done correctly we can have a single block for all 4 boards, but again I am waiting for my sample to get to my photos will be up once I get my sample.

The extra $15 is to cover the $500 I had to pay for set up/design fees.

Im down for this.... Anything to reduce the noise so i can run all day & night at full speed....

I have to turn my miner down at night to the lowest speed & then use smits fan hack to slow it down more so i can run it at night.... Mega painful

PM me with details asap..

Do u have a price estimate on these??

Plus shipping to Australia??

i have a PSU dps2000, so watt are not the problem.

could it be possible to have the firmware Oct-16  "powered" with other cgiminer ?  or other Smit firmware able to overclock ?

I remember to read something , but i can not find the post detailing this info.

For anyone that cares I will be offering a S4/S4+ Water block, and Kit in the coming weeks I just need to get the engineering sample.

Let me know if anyone wants in I'll have 100% pricing with in 2 weeks.

Most likely nothing you can do about the temperature probe.

Overclocking will benefit from the 20141016 firmware, I've got a copy if its not still hosted. You really don't have much headroom on the stock PSU though and that will be your limiting factor.

Dear
could I get help for my S4.
Miner Status is showing a temperature ASIC value of 0, other 3 values are OK.  how could I fix it ?

Other question...  I want to overclock, so what firmware must I use ? I readed only Oct-16 firmware is able to overclock.
but is there other posible solution ?
thanks

Result so far: 

I tried the above and fans did not come on.

When connecting Red-Red, Blue-Blue, Black-Black and leaving the 4th wire, (old fan White, new fan Yellow) disconnected, the fan comes on and runs full speed.
This is obviously because the sensor is disconnected.  Fan speed also shows 0 for fans 2 and 3  in mining status screen.
S4 is mining at full expected rate and temperature is good after running for an hour.

I would say that I am happy with the result.  Now I have a working S4 that would otherwise not be working.  Fans were $12 each on ebay.

Unless someone can tell me something more about the sensor wires, I think I will leave it alone and let it do it's job.

Also a word of warning.....  Don't hold a running fan in your hand, it will fly away, and keep your fingers away from the blades....  OUCH!

The post was right blue is sensor on the original S4 fans. I think on most fans if you take the stick of you reveal the control on the empty solder. You will know what i mean when you take of the sticker of the fan. for fan 1 it's the pin furthest on the right when looking through the window at the control board fans 2-4 it's the pin to the furthest left. You must have four wires running to teach pin. Take a look back at page 138 to get a visual of how the set up is. black is ground white and red a both power those compose standard three pin. that's where you connect if you have just three pin connector. Blue is control.

Guys I never really did get an answer. Is there a "drop in" power supply that is already complete that I can replace on my S4 thats higher quality than the bitmain oem psu?

Given that black is ground in all the examples, and blue is control, I probably need to switch the other two wires.

Thanks,  I'll let you know.
