SXDOOL 120mm 24V Server Fan

This 120mm case fan runs on a 24V supply and spins at 3100rpm to move 108 CFM of air. It fits standard 120mm mounting points with a 25mm thickness. The unit is designed for server chassis and industrial enclosures that require consistent airflow.

Thermals noise and power draw

Rated power is 5W with a working current of 0.21A at 24V. The fan produces 44dBA of noise while generating static pressure of 0.26 to 0.32 inch-H2O. It operates reliably across a service environment of -20°C to 85°C.

Replaces Sunon EEC0252B1-000C-A99

This model serves as a direct replacement for the Sunon EEC0252B1-000C-A99 12025 fan in compatible server hardware. The upgrade is worthwhile when the original unit reaches the end of its 50000-hour service life or develops bearing noise. It is not for builds that require 12V power input or PWM speed control.

Questions about this item

How do I install the 120mm 24V fan and what polarity mistake should I avoid?

Mount the 120 x 120 x 25mm frame with four screws, connect the 24V supply to the positive lead and ground to the negative lead; reversing polarity will prevent the motor from starting.

What maintenance does the 3100rpm fan need and when should I replace it?

Clean dust from the blades every six months; the rated service life is 50000 hours at 24V 0.21A, so plan replacement once running time approaches that figure.

What thermal limit appears first during continuous 24V operation?

The motor is rated for ambient temperatures up to 85°C; sustained operation beyond that point will trigger the first thermal limit.
