Fans W1G200-HH77-52 24V 2.6A 55W 2950rpm 200mm case fan

Axial cooling fan for high-airflow builds

The Fans W1G200-HH77-52 is a 200mm axial fan designed for systems that need substantial air movement in a single unit. It suits server enclosures, workstation chassis or custom cooling loops where a single large-diameter fan can replace multiple smaller units. The all-metal construction and ball-bearing motor are rated for continuous operation in demanding environments.

Integrates into 24V DC power architectures

The fan operates from a 24V nominal supply with a supported input range of 16 to 28V, drawing 2.6A at full speed. It requires a 24V DC source capable of delivering 55W and a speed-control interface — analog or serial — for 100% PWM or voltage regulation. Polarity protection and locked-rotor detection protect the motor if wiring is reversed or the impeller stalls, simplifying integration into existing fan-controller hubs or motherboard headers that supply 24V.

Ball-bearing motor rated from -25°C to 60°C ambient

At 2950rpm the fan consumes 55W and generates up to 120Pa of static pressure while moving up to 35000m³/h of air. The metal frame and external-rotor motor dissipate heat directly into the airstream, allowing operation across a -25°C to 60°C ambient range without thermal throttling. Ball bearings and the all-metal chassis keep acoustic output consistent over the unit’s service life, avoiding the rattle that sleeve bearings develop under continuous high-speed rotation.
