I wonder if there are stats on how often liquid cooling fails on miners. I'm a computer enthusiast myself, and I noticed that some people stick with air cooling for various reasons, including easier management. I've been using one for my computer myself, but I expect the stress will be higher if you're using it to cool a miner. My country is quite hot too, I wonder if there'll be any difference. I don't know someone to test them nor can I do it myself sadly.
Ready-made solutions like mining containers have many drawbacks, according to miners.
A huge advantage of water cooling is that it can be built using plastic pipes, pumps, and radiators, and many miners do this.
This is usually done for additional utility, such as heating a house, a pool, or a greenhouse. In other cases, air cooling is cheaper and simpler.
