Air Cooler for a Computer: Choose a CPU Cooler That Fits

A PC air cooler is a heatsink and fan, unlike a portable room cooler.

Computer air cooling is separate from portable appliances. A tower heatsink transfers CPU heat into case airflow; an AIO moves heat through a liquid loop to a radiator. Check socket, cooler height, RAM clearance and radiator positions.

Common questions

Questions before you buy

What does an air cooler do in a computer?

It transfers processor heat to a heatsink, where fans move air across the fins.

Will any CPU cooler fit my motherboard?

No. Check socket support and case clearance.

Is an AIO a liquid cooler?

Yes. It circulates coolant between a processor block and radiator.

Do I need an AIO for gaming?

Not necessarily; match the cooler to processor load, case fit and noise preference.
