why the fuck would you make a DC in bangkok! where is 28 degrees Centigrade at 9AM, right now!!! WHY!!!

Miners don't particularly mind hot ambient, and because you're not running AC neither do you particularly. Instead of replacing the air with an infinite amount of 20C air, you're replacing it with an infinite amount of 30C air.
I'll drive constantly at 200miles/hour just because my car can do that! I dont give a fuck about road conditions or tires...
better 10cents/kw in a 0C temperature climate than in that location with +30C temperature and 6cents/kw!
Based on what? If you're able to bring enough 30C air in to feed the units and keep them cool, there's no real need for the 0C air. Yes you could run the fans a little slower and save a bit on your cooling costs, but you're talking maybe a percent on of your budget. Nowhere near enough to justify 10c vs 6c.
Teal, you'r forgetting that 30°C air is a lot wetter than 0°C, expecially in some places. You can't cool down 5MW of electronic HW with 30°C air without think about humidity.
Also 30A are enough for a bad contact to burn a wire, and a fan that blows air direct only helps fire to catch on. That is why in industial plants (not btc related) A/C , thermography, proper electrical distribution and extinguish systems are used.
If it's true that this farm was using 5MW, the lowvoltage threephase distribution system should have handled about 8000-9000 Amps , no peanuts.
Absolute humidity will almost always be higher at 30C than 0C, though relative humidity can vary and that is what would cause an issue for condensation. If it's really muggy you might be worried about that, but mining equipment will almost always be hotter than the surrounding air you shouldn't have many condensation issues unless the conditions are extreme.
Not saying you couldn't put them in a place where you could run into issues, but if your gear has a low enough ΔT that it is able to run in a comfortable range with 30C (or even higher) ambient the benefits of the colder climate wouldn't come close to outweighing paying 67% more in electricity costs.
