Air: manage the whole airflow path
Fans move air across the hardware. The site must admit cooler air and remove heated exhaust without recirculation. Noise, dust and ambient conditions become part of the installation decision. Size ventilation from the actual equipment and site assessment rather than a generic machine count.
Hydro: the miner is one part of a loop
Liquid-cooled hardware needs a compatible circulation and heat-rejection system. Fluid quality, inlet conditions, flow and pressure are model-specific requirements. Pumps and cooling equipment consume electricity too. Use the exact manufacturer manual; the S21 Hyd. guide is one example, not a specification for all hydro miners.
Immersion: check system compatibility
Immersion places compatible equipment in a dielectric fluid and transfers heat to another circuit. Fluid compatibility, service access and warranty terms need written confirmation from the equipment and system suppliers. Do not assume an air-cooled model can be converted without consequences. Treat every conversion as an engineering decision.
