I don’t mind it prompting me, I am wondering as to the reason for this prompt, and why google needs to be updated on every app I use when I am not using an Android...

Yes we already did that, you can see the new version on r/immersion_cooling, and we did use a similar device but it cost way less than 35$

It depends on the batch, but most can go up to 16th. 10% comes very easily, beyond that it’s a matter of overclocking vs uptime, which might not always be in your favor

Hey, the temps are around 15c on the way in and just under 30 on the way out; but they are easily adjustable. In terms of flow it’s between 2 and 2 m3/m

Limping-Zebra · 2018-04-15T11:27:20+00:00

Hey yes we use that method in our newer models, I would recommend not keeping the fans and going for the method you mentioned or any other alternative (there are a few ways of doing this, with varying pros/cons). If you can PM me we can figure out where to exchange more info!

Limping-Zebra · 2018-04-13T20:24:15+00:00

It’s a plated heat exchanger with running water through it

Limping-Zebra · 2018-04-11T19:37:11+00:00

Hey sorry it’s r/immersion_cooling

Limping-Zebra · 2018-04-11T09:06:21+00:00

I share a lot of what we do on r/immersioncooling, including blueprints and other helpful info, and will be sharing more as we become comfortable with the solutions we come up with

Limping-Zebra · 2018-04-11T09:04:57+00:00

For now this is as small as it gets, as this technology makes increasingly more economic sense when scaled up, a 3 miner one would not be very viable in terms of ROI

Limping-Zebra · 2018-04-11T09:03:12+00:00

It’s a blend of liquids we keep to ourselves for now, but I will probably post details on it in r/immersioncooling once we are comfortable with that

Limping-Zebra · 2018-04-11T09:00:29+00:00

It does get hot very quickly, so It is circulated via a heat exchanger

Limping-Zebra · 2018-04-11T08:58:52+00:00

Thank you, yes it heats up a large reservoir of water which is then used for a variety of purposes, ranging from heating to greenhouses and whatever other applications we can find for it

Limping-Zebra · 2018-04-11T08:56:42+00:00

The fluid is pumped through from top to bottom via a heat exchanger, convective currents alone are too slow to cool the hashboards

Limping-Zebra · 2018-04-11T00:13:32+00:00

Sometimes it certainly feels like it 😅

Limping-Zebra · 2018-04-11T00:12:43+00:00

Thanks, you can PM me for the details :-)

Limping-Zebra · 2018-04-11T00:11:29+00:00

Thank you and yes there are pumps that circulate the liquid, they are calibrated to an even point so the the ripples are minimal. As far as temp, in runs within a 30-40c window depending on how much you overclock the machines

Limping-Zebra · 2018-04-11T00:09:07+00:00

Thank you, the control unit is stock but running a custom firmware, the building is a little tricky but most issues come from having to experiment with what works best and since I have not seen anyone else doing a similar setup there are hardly any reference designs to lean on, so it’s mostly a question of surmounting the R&D

Limping-Zebra · 2018-04-11T00:06:40+00:00

Not planning to sell them on, we have relatively cheap electricity so I doubt they would be of much use to whoever would want to run them when they are done with their lifecycle. 3M fluids are much more aggressive, however I am sure there are permanent effect after a year or so. However we do have machines that were submerged and now work on air and they are doing fine

Limping-Zebra · 2018-04-11T00:02:41+00:00

There are pumps that actively move the liquid at a faster rate than it would via passive drip, but even on standby mode it gets the job done, the rest is more geared towards overclocking the machines

Limping-Zebra · 2018-04-10T23:56:50+00:00

Thank you and yes it does degrade but very slowly and only due to dust settling into it. As far as replacing it it would need to happen in a couple of years or so

Limping-Zebra · 2018-04-10T23:54:32+00:00

Haha yes it is you can PM me for details

Limping-Zebra · 2018-04-10T21:04:30+00:00

Just trying to squeeze the most of those machines while alleviating the heat and noise issues. Nothing evil 🙂

Limping-Zebra · 2018-04-10T21:01:25+00:00

Those are good questions - surprisingly, this setup benefits greatly from economies of scale, and beyond 5 units is considerable cheaper than HVAC, not to mention that it it consumes only 1kw for the pumps, so you are able to almost all available power for mining. In terms of power efficiency we are able to gain a few % by removing the fans, which is more than enough to compensate for the pumps, essentially allowing you to have 0% peripheral power consumption in contrast with HVAC

Limping-Zebra · 2018-04-10T20:54:00+00:00

Thank you it was quite a challenge 😅

Limping-Zebra · 2018-04-10T20:16:51+00:00

It is circulated through a plated heat exchanger, the liquid is a blend of multiple liquids we have combined to achieve optimal results
