BTC-Farm
It all started with Bitcoin.
My first farm after GPU mining, is a small BTC farm, consisting of 2 Bitman Antminer S9.
I'm not a normal computer scientist and miner.
I always try to get the most out of hardware, and get the most out of the software.
Here run the firmware from Dollemizer. Both S9, work with a maximum hashrate of 17 instead of 13.5 THs.
Make S9 quiet (also with: NF-A12 industrialPPC-3000 (https://noctua.at/de/nf-f12-industrialppc-3000-pwm))

Remove standard Fan
Mount fan simulators or via firmware disable the "fancheck".
Here in this case, I have opted for the fan simulators because I operate the Noctua fan with an external power supply.
Finally, install the fan and you're done.
Test and observe temperatures.
That's it
