Compact 5 V CPU Air Cooler

This 5 V 0.40 A fan unit fits standard CPU air cooler mounts and draws minimal power from a motherboard header. It is intended for builders replacing a noisy or failed stock cooler in a small-form-factor or office system.

Not for high-heat or overclocked CPUs

The low 5 V 0.40 A rating limits airflow, so the cooler cannot handle processors with high thermal design power or sustained heavy loads. Buyers who need greater heat dissipation should select a higher-wattage cooler with a larger fan and heatpipe array.
