What is the the difference between and air cooled system and water cooled system?

Question

Accepted Answer

Air cooled systems use air to dissipate heat while water cooled systems use water to dissipate heat.

Air cooled systems are typically smaller and less expensive than water cooled systems.
Water cooled systems are more efficient at dissipating heat than air cooled systems.
Air cooled systems are often used in smaller applications such as personal computers and small electronics.
Water cooled systems are commonly used in larger applications such as industrial machinery and power plants.
Water cooled systems require a constant supply of water, while air cooled systems do not.
Air cooled systems are generally easier to maintain than water cooled systems.
