Hey guys,

I've been working on a new project for the past months, and here's a video on how it looks so far:

Let me know what you guys think of it.

Thanks!

Interesting work.  Did you use the stock controller?

so 40th and about ? watts

So these are basically 6 boards from 2x S9j miners, right?

maybe  they are the waterblock cards

Thanks! 3800 W for power usage and yes, it's stock controller but I added three more ports to the board.

They are antminer s9i boards, it will work is s9j as well.

No, they are not s9 hydro boards, I am waiting for that to see what's inside.

Alex is using the s9 waterblocks you can find from alibaba if memory is correct.

That's neat.  Is the s9 different than the s9i?  s9i already mines at 14.5 per bitmain.

No, I've designed my own blocks, the alibaba ones are not fitting properly on the board.

This will work on any S9 machine with a board versions higher than v4 . The older versions don't overclock very well,
but they can be run at smaller frequency. The chips are the same but the power module is more stable on the board,
that's why it allows better OC.

So is there any economic benefit for you to use this rig, instead just using S9?
29 TH @ 2800 WATTS
39 TH @ 3800 WATTS

How much did it approximately cost to buy the equipment and make it work?

Really cool. sounds just as loud as any other asic. Any idea in db's?

Here's the main advantages of using such system:

1.   The heat is being driven to exterior very easy. You can install a heat exchanger and benefit from the hot water.
2.   Reduced cooling costs, it can be cooled with running cold water or with externally mounted radiators
3.   The allows overclocking IC’s with 40%, obtaining more hashing power with less units.
4.   Reduced service costs, the water blocks are easy to disassembly.
5.   Increases electronic components life span, running between 35 and 50 degrees in comparison with 58 to 95 degrees with air cooling.
6.   Eliminates the necessity of air filtration.

For the costs, for 6 boards, the conversion kit is $2000, this includes the following:

1. 6 x waterblocks kits (12 waterblocks in total, as it's one waterblock for each side
2. 36 Thermal pads used between the board and waterblock
3. Thermal putty for the CPU's
4. 12 KW water radiator, capable of running at outside temperatures of over 45 Degrees Celsius and still keep the machine at optimal temps
5. Water pump 3500 liters per hour
6. Watter fittings and water distribution system
7. 2 x 2400 W PSU's

The noise will be under 40 Db, it was noisy because of the PSU fans, but I changed those to bigger fans and solved this issue, I will upload
another video soon explaining all the functionality and safety features.

So it costs $1000 in parts to mod a single $400 s9....please explain how this will ever even come close to breaking even let alone achieve some small amount of profit.

This seems like a massive waste of time and money for a negative return.

Sometimes we do things because we can and it's fun.

Hi,

As i want to try a totally different approach, im curious if you'd sell solely the waterblocks, and what they would cost.

Also interested to know how you remove the cooling fins from the chips without breaking them... ?
