In fact, the local environment and climate are not bad, and the electricity bill is not high. Air cooling or water cooling can be used. It also depends on local conditions. You can choose the one that suits you according to the situation. It can only be said that directly choosing water cooling is not so troublesome.
I have already written about my colleagues' experience with water cooling from Bitmain. They had enough problems and a very long time to buy the necessary spare parts, which are expensive, and so they began to make this system from materials that can be bought at any store for plumbers. This is more expensive, you need to have additional workers on staff - plumbing engineers.
