Air cooling: An internal fan draws in outside air and blows it onto the heat-generating components, using air convection to dissipate heat. This method does not require a water source, but it generates waste heat, so good ventilation is essential.
Water cooling: Utilizes cooling water to absorb heat, which is then circulated and exhausted to the outside. It offers higher heat dissipation efficiency and does not generate waste heat indoors, but a stable water supply is required.
