Last week, I attended a tour of Just for Krypo's mining facility with the MN Crypto Council. They have 4,300+ miners (almost all BTC miners) in their facilities. They have a whole wall of air-cooled miners with a "cold" and a "hot" side. Video below is our group on the hot side.
The next, briefer, video is from the cold side. You can see all the miners in a zig-zag wall pulling cold air from the room and pushing it out to the hot side. Fans in both rooms help the air flow.
In the main part of their building, Just for Krypto runs liquid-cooled miners. The fluid is dielectric, and the miners can be safely immersed in it. Still, it was weird to see a computer completely "underwater." The fluid looks and feels like olive oil.

The outflow of warm fluid travels out of the building to cool outside before returning into the bath. I believe that each bath holds about 40 miners.

| Outflow was about 120 - 130 degrees F |
The last part of the tour was their outside mining. With the potentially hot summers and very cold winters, miner temperature regulation is a challenge.

We had dinner after the tour, and the great crew answered many questions. Their growth so far and their future plans are both tremendous.
