Desktop CPU Cooling Fan 644724-001

This 4-wire desktop CPU cooling fan uses aluminium and plastic construction to manage processor heat. The four-wire interface supports pulse-width modulation so the system can regulate fan speed based on thermal load. It is suited to standard desktop builds that require active heatsink cooling.

PWM control and material limits

The 4-wire PWM connection allows automatic speed adjustment but requires a compatible motherboard header to function fully. Aluminium and plastic materials limit maximum thermal dissipation compared with copper or all-metal designs. Buyers needing higher airflow or quieter operation at equivalent RPM should consider fans with larger blades or alternative bearing types.

Questions about this item

Which 4-wire CPU fan version matches the 644724-001 part number?

The 644724-001 is a single 4-wire desktop CPU cooling fan with an aluminium and plastic heatsink, so the part number itself identifies the exact version to order.

What does the 4-wire connection actually do once the fan is installed?

The fourth wire carries a PWM signal that lets the motherboard vary the fan speed precisely, keeping the CPU cooler under load and quieter when idle.
