Hi all,
Today i finished most of the work on my new mini-farm.
I thought i'd share it here, in order to bring other people on good ideas.
I just took the effort to transfer th pictures to my email, put in a folder, upload, adjust size, and upload to forum. Its quite a task, and now the pics are turned 90 degree, so please rotate your head or monitor please
I will edit and add more text while i upload this.
The story:
Last year i started to mine with innosilicon miners that i bought secondhand. This was so profitable, i bought another 4 sets.
I started to read about mining, bitmain, etcetera. I sold my Innosilicon's A4's with good profit and ordered 7 S9's at Bitmain.
In the waiting process, bitcoin rose and rose and rose, and i had nothing to mine with! So i bougt 4 S9's on the market for more money (yes, i roi'd.) (man.. these things were loud!)
My barn started to heat up, and the messy way they were situated irritated me, so at first, i bought a big most silent roof fan that i could find. It had a capacity of 4000 cubic meters an hour. This meant that when it was running, i couldn't open the door of my barn! Clearly i had to make an opeining for fresh air inlet, which i did.
I bought me a 19"rack, and started preparations for the arrival of the 7 S9's.
I insulated the whole rack, and made a hot outlet divider in it. I had the big roof fan connected to the top, and fres air came from below and front.
Result is shown in the first pictures.
Miners arrived, and were added.Weather was quite cold, approx. arount 0 centigrade. A tad noisy, but it was okay.
This worked great, until temps started to rise, and i had to speed up the roof fan, and sometimes had the front door a tad open to let more fresh air in.
Neighbors started to talk to me if the noise could be down during the night, which i did, monitoring with awesome miner.
Then i got it:a big fridge! Totally insulated itself, so adding some sound reducing on the inside should do it!
I bought 10 plates of 8cm (approx 3 inches) thick, and started to insulate the inside. (for the record, the space where thefridge is situated, i insulated the walls and floor as well; the fridge is placed on it)
Fridge cooler has been removed.
Then i started to build a custom fit shelf for the miners. See pic.
Today, i transferred the miners to their new habitat
As i need to redo power and network, and place the PDU's in the new undercome, things look a bit messy right now. I will make it nice coming weeks, i promise
First results: incredibly better cooling (the shelf sits approx. 20cm / 8 inches from the back, and top left there's a big hole with a flange to the rooftop fan. It sucks away the hot air and does a perfect job in that.
I have Sonoconnect hose to replace current suction hose, and to make a forced air intake to the cold side if the fridge. I intend to make them temperature controlled, and pressure-difference controlled as regards to the intake.
Nice story huh?
advises?
