An watercooled BitCoin miner (with ROG included)

Hi! to all! well, this is my brand new project, something totally different for me and for the forums, so... i can start now the explain about this brand new project:

This days, talking with my uncle, about things of the bitcoin, and things like that, a new idea comes into my and my uncle heads... create, design and build a massive miner, with lots of power, and lots of power consumption (probably 10k - 20k Watts ;)) and about 8 - 20k GH/s of mining power), well all this project will can have the good check in this coming week so... we have to wait some time hehehe, now... the things than can be inside this "different" build:

- 20 or 40 Bitcrane UltraHoist Miner cards (they can be 40 cards if the 2 investors give me the good check to the project)

- 2 or 4 Cubieboards with Bitcrane mining controller system (1 cubieboard for 12 UltraHoist Cards)

- 10 - 20 NZXT Hale 90 1000W PSUs (1 PSU for each 2 UltraHoist Cards)

- 4 or 7 6 to 1 USB Hub (for connecting all the cards) and another 2 more, Anker 7 to 1 USB hub, to connect the hubs to the mining controller PC

Let's continue this advice... how i can keep cool this lot of cards?... with a custom watercooling loop, this is my proposal for do this job:

- 20 or 40 EK Supremacy EVO Nickel/Plexi waterblocks (this perfectly fits on each card)

- 2 or 4 EK CoolStream PE 480 Radiators (1 rad for each 10 cards)

- 1 or 2 Bitspower Water Tank Z-Multi 400 (1 for each 20 cards)

- 8 or 16 EK Vardar F4-120 2200RPM PWM Fans (4 for each 1 rad)

- 50 or 100 EK 3/8" - 5/8" Compression Fittings hehehehe 😛

- 2 NZXT Sentry 3 to control thats fans

- Pump... i have a problem here... i don't have any idea if 1 Aquastream XT can had the power to supply good flow to 20 water blocks, 2 rads 1 reservoir loop or if i need 2 pumps to each loop, what you think guys? and... a Aquastream XT are more powerful than a D5 EK version?

im planning on how can be the specs of the mining controller pc so i will post it later...

well... guys... what you think about my project, deposit your comments below and im glad to reply it! and, please, help me with my pumps problems!

Thanks! 😄 :cool:

you need at least 2 x 120 rad slots for each card since they are going to fire on all cylinders when mining.
and TBH? not worth the monney now compare how it was 10 years'ish ago.

each waterblock will limit the flow, so no need to get thick tubings.
2 cards per 480 rad.
the aquastream xt communicates whit the motherboard onboard usb headers, and the interface is controlled by a software.
you need a room that is cold to keep it cool.
4 or max 6 cards per pump.
250-400 mm res per pump and the reservoars are standalone.

Thanks KKN for you comment! well, the cards itself doesn't produce much heat, i have 2 in home now and they are working at 57 degrees (celsius) at full load, with air cooling, so, well, i think 4 or 5 rads can keep under range the cards

thats something true, each waterblock limits flow, but... i have to put thicker tubing?

hummm and the aquastream can be powerfull than a D5? i see in your link that you used a aquastream, whats your opinion about it, i have already used D5 but no the aquastream :S

with the room i don't have problem hehehehe, why that configurations of reservoirs? (sorry i don't understand it very well)

well about the profit of the mining work, for me in my country 20TH/s or 10TH/s give me some cash, specially in dollars (because of this, pay the power consumption doesn't are a problem, 1 dollar can pay the half of my current power consumption in bolivars hahahahaha, well im Venezuelan, and well im sure you know the problem who took place in my country hahahaha)

Thanks KKN!

*tubings dont help flow mutch, im using 10/13mm on mine, and waterblocks takes away mutch of the preshure ( flow ) and makes water go slower.
the pump is expensive, it have built in temp probe, speed can be controlled in the program ( just little bit only ) you controll it by HZ not rpm.

It bugs me to see pressure and flow equated. Yes, the waterblocks will restrict flow, however, one could have a partial bypass around blocks. Of course, with the pumps used commonly in watercooling, the higher the pressure, the lower the flow. I study this as part of what I'm working on making a living on it. You could, relatively easily, if you accepted the need to use a positive displacement pump, get up to ten GPM through a water-block. It's not at all useful. Sorry for the pedantic rant. More on topic, I very much suggest more res space, and more radiators, as well as breaking each 5 cards at most into it's own loop with res, rad, and pump, in order to allow more granularity for rebuilding, or refilling. Pumps not only have a maximum flow rate, but a maximum pressure developed, and with the resistances of multiple cards, it won't get through. Pumps in series are not additive, whereas pressure loads are.

yes! thats the problem im really worried about the pump because after the waterblocks they are the most expensive parts, and i have that problem, i want use some pump that have a lot of power, with the best flow, i know that the D5 are a really powerful pump but i don't know anything about they performance (in flow) used in loops than are a "little bit" more exigent hahahaha, im thinking now in DDC pumps but, i don't know much about it, and i think that i have to use 3 in every loop hahaha

what you think?
and thanks for your reply to my thread Xenocrates 😄

i used the 3 sizes of tubing before... and some restrict more flow and another less flow, this obviously depends on the configuration of the tubing, the angles of they can have in the loop and the inches used to connect every component.

so... what you think about instead of using the Aquastream's pumps i can use some D5? they can go better for this project? because i need some really powerful pumps (if you have in mind another pump, please comment it 😄 )
