Air Cooler vs AIO: Which Kind of Cooling Do You Mean?
An evaporative air cooler changes the air in a room using water; an AIO cools a computer processor with a sealed liquid loop. They solve different heat problems.

The verdict
There is no direct winner until the target is clear: choose an evaporative air cooler for personal or room airflow in suitable conditions, and an AIO for processor heat management. Neither replaces the other.
Cooling a room with water-based air movement: De'Longhi EV250.WH
It is an evaporative room cooler with a listed water tank and airflow specification.
Removing heat from a desktop CPU: ARCTIC Liquid Freezer III 360
It is a CPU liquid cooler with a radiator; it does not condition room air.
Moving air without adding water: De'Longhi EV250.WH
Its fan can be used separately from evaporative cooling according to the product controls; a standard fan is another simpler option.

Common questions
Questions before you buy
What is the difference between an air cooler and an AIO?
An evaporative air cooler is an appliance for room air; an AIO is typically a sealed liquid cooling assembly for a computer CPU. The shared word cooler does not make their use cases interchangeable.
Is an AIO better than an air cooler for a 7800X3D or 9950X3D?
For CPU temperatures, compare compatible CPU coolers, case clearance, workload and noise. A room evaporative cooler does not cool a processor directly.
Air cooler vs electric fan: which should I choose?
A fan moves air without a water tank. An evaporative cooler adds moisture while passing air over wet media, so climate and ventilation affect whether its cooling method suits you.
Is an evaporative air cooler the same as a humidifier?
No. An evaporative cooler moves air through wet media to create a cooling breeze and may raise indoor humidity; a humidifier's primary purpose is adding moisture.
