I am working on a excellent Idea which is working very well and only Takes Between 1-2 hours to do. not saying anything To Many credit Stealers and design thieves out here.
Topic: ANTMINER S3+ Discussion and Support Thread - page 90. (Read 710164 times)
Was the idea to have a channeled heatsink on each board positioned as they are now in the S3's? I confess the sandwiching idea comes from looking at the C1. But that cover doesn't look like it would lend itself to modification with a nibbler for new PCIE positions.
No, the 2 slabs would sit in the middle joined together (just like the C1), so the backs of the boards would have full contact with the un-channeled faces of the slabs. Then over the chips would be copper tubing with a separate routed heatsink sitting atop them. I have to say that with the S1 boards' design, the idea behind the top heatsink had a flaw in that the copper tubing would have to sit atop another copper square the size of the chip to lift it clear of the resistors either side (which would probably have made it more expensive and fiddly). Add to that, there would not be any board contact on that side to the heatsink (a missed cooling opportunity maybe). For the new S5 boards, it seems to be well laid out such that the chips are on one / internal side and the supporting circuitry attachements on the outer side.
Of course now we see using a half round routing bit to run tracks for the copper tubing in the aluminum slabs. Having the faces flush would really be better so as to reduce warping due to temperature differences that might lift the slap from the PCB.
I was looking to fashion the aluminium slabs on my very own CNC mill and was more confident of achieving the (percieved) required accuracy with square routing, leave alone that I do not have a half round routing bit! Saying that, I was also looking to run the tube over the chips, embedded or not in an aluminium slab, (on the S1 board) and a round tube would not have worked.On having the faces flush, yes I suppose that would reduce the warping, but I never got that stage for that to be an issue.

Watch that condensation if you are going to use a Freon system.
look at the c1 slap pump Freon through it instead of water or anti-freeze mixed with water. hmmm lines are pressurized to 100 p.s.i how would you put them on ?

Personally going to Freon would be too much given that it will vaporize if free and without a compressor how is it better than 50/50 auto antifreeze/water (the non-hole plugging antifreeze)? Maybe it has good thermal carrying characteristics (under pressure) but so does water/antifreeze (non-pressurized). With a pre-cooling radiator outside, heck even an old junkyard radiator would work (leaking, plugged with J B Weld). For some months I have a window fan exhausting heat before I turn on the AC. Mid-summer, a window fan outside on low pushing air thru a car radiator before it's routed back in to the stock fans/radiator might not be too costly if there were multiple machines.
How are these stats not even 24 hours yet.

Let's see. Two aluminum slabs the dimensions of S3 heatsinks drilled and tapped to fit S3 boards, additional thru holes to sandwich two slabs together. Copper tubing loops dragon-like sandwiched between the aluminum slabs contacting the slabs well with heatsink compound.
Hey! I had a similar design but could not find square copper tubes cheaply and easily (I probably did not look hard enough).My plans were those of milling 1/2 the length of the tubes as tracts on 2 aluminium slabs (thus the square tubes) and laying those tubes inside one slab then laying the other slab on top, and then fashioning my own radiator, again from the copper tubing tied to some mesh but these never left the drawing board for the above reason.
EDIT: If bitmain start selling boards on their own, this is one project I will revive as I was planning on doing this with the S1 boards I had left over from my upgraded ones. I now run them underclocked and air cooled ... but would have been a good pilot project for the S3 / S5 boards.

Hummm.. S3 and S5 hashing PCB only sale? That may be hard with warranty as improper heat sink or heat management may kill the chips on the PCB.
sold as is may be... still, let me send your idea in as well. Thank you for the input!!

No warranty is not a problem at all! I trust bitmain would not sell me a defective board, in the same way that when I buy a complete unit from them, I know the warranty may not cover my overclocking .... I still overclock them!

Hey guys!
If you have a cool looking inventions with Ants, Share the Photo or Videos please!!
Would love to see them, but please consider original warranty as if you modify the miner... (I had to put that it out here as a small print...)

Somebody with a machine shop could whip those up and offer then for sale to S3+ users who want to roll their own water cooling.

I was thinking of using an old a.c unit solder the tubing on to the c1 heat sink make sure it don't leak Freon after I recharge it then mount heat sinks back on to the miner. This might produce to much moisture between the heat sink and the hashing board!!! POOF!!! there goes the miner.
Besides, if you don't purge the freon properly before heating, like if it's from an older AC, you'll produce a gas that causes massive chromosomal dislocation. Very unhealthy stuff.
C1 uses a similar looking PCB to S3 or S3+ hashing PCB, but it is little different, so Please DO NOT mix them as the connector even facing differently.
just FYI

you should have bought s5 instead less power usage.

The C1 water cooling block does Look like it would fit on a S3 hashing board but the price of them would be to expensive unless you can get them Custom made for cheap.
Then you still have to buy pump , Connectors , tubing.
Just buy a C1 outright its cheaper. plus you get double the speed anyway.

I have and am awaiting it now.
I happen to have a couple of radiators from an old window AC. I do think I'll have one outside in series with the provided C1 radiator. I started using my S3+'s late in the fall. I'm thinking with the profit margin so low I may have to shut them down next summer unless I can get a cooling solution that doesn't jack up my electric too much.
What is that number that says activity under your profile 
?
Help please I am new.
its your post count.. ?Help please I am new.
and the S5s plus shipping seem to be the same price as the s3s were with free shipping.. and they are faster and take less power.
The S3 at the time was an industry leader. They were at the forefront of new technology. The S5 is old tech compared to the competition.
They aren't however going to return a positive investment unless you have free power.
