50 mm 4-pin server fan

The SXDOOL EFB0512HHA is a 50 mm case fan built for compact server and inverter chassis. Its 4-pin connector enables PWM speed control so the system can adjust airflow to match thermal demand. The double ball bearing supports continuous operation in space-constrained enclosures.

Sustained 6400 RPM airflow

At a fixed 6400 RPM the fan delivers 16.24 CFM while producing 36 dBA of noise. The 0.20 A draw at 12 V remains steady during extended duty cycles. Double ball bearings maintain consistent speed without the lubrication degradation common in sleeve designs under constant load.

80 000 hour bearing life

The double ball bearing is rated for 80 000 hours of continuous running. The 50 mm by 10 mm frame fits standard 5010 mounting holes in server and inverter units. A 4-wire lead provides tachometer feedback for hardware monitoring without additional adapters.
