Architect here. What humidity level are you talking about - percentage wise.

The humidity level in IT rooms can range between 45 to 85%. This is ok. But ideally 40 to 50% should be the range to aim for. The problems normally arise when there is a rapid temperature drop. For example if temperature is hot and humidity is high and the temperature quickly falls, then moisture can drop out of the air and appear on hardware.

The question that might need to be asked is where the humidity is coming from. Miners don't sweat. I hope you don't have many people in the room. I suspect its outside air. Is the outside air being dumped into the farm unconditioned?

If the mechanical design for the farm is correctly designed then the HVAC would have an integrated dehumidifier.
