Convection.
Better heat transfer than natural convection. When compared to water or liquid cooled heat exchangers, the argument could be made that air is a cheaper cooling medium.

Normal convection occurs naturally due to temperature differences, while forced convection is induced by external means such as fans or pumps. Forced convection typically has higher heat transfer rates compared to natural convection due to the enhanced fluid motion generated by the external force.
The three main types of convection are natural convection, forced convection, and mixed convection. Natural convection occurs due to density differences caused by temperature variations. Forced convection involves the use of external means like fans or pumps to enhance fluid movement. Mixed convection combines both natural and forced convection mechanisms.
velocity of fluid..
Convection typically occurs in two forms: natural convection, driven by buoyancy forces due to temperature differences, and forced convection, driven by external factors like fans or pumps. Natural convection occurs in fluids (liquids and gases) due to density variations caused by temperature gradients, while forced convection involves the use of mechanical devices to circulate the fluid.
Heat vents are an example of forced convection. Forced convection occurs when a fluid motion is caused by an external source such as a fan or pump, as opposed to natural convection, which occurs due to density differences in the fluid. In the case of heat vents, the air is circulated by a fan to distribute the warm air throughout a room.
Convection caused by frontal or orographic lifting, or converging surface winds.

True
Forced convection is when air ascends as a result of another force, such as the actions of fronts, orographic lifting, or converging wind. Free convection is caused by a factor such as intense heating of the Earth's surface, which warms air and causes it to rise.
