120 mm 4-wire PWM case fan

The SXDOOL A12025-18RB-4BP-F1 is a 120 mm case fan designed for standard chassis ventilation. It connects via a 4-wire PWM header for automatic speed control by the motherboard. The unit operates on 12 V DC and draws 0.32 A. It suits builders assembling or refreshing air-cooled systems.

Capacity and headroom

The fan delivers 12 V PWM airflow for typical case cooling duties. It handles moderate heat loads from mid-range components in standard ATX or micro-ATX builds. It is not intended for high-static-pressure radiators or dense mesh obstructions. Buyers needing higher airflow or specialised radiator performance should consider alternative models.

Questions about this item

Will the 4-wire PWM connector on this 12 cm fan work with my older motherboard that only has 3-pin headers?

Yes, the 4-pin plug fits a 3-pin header; the fan will run at full 12 V speed but PWM control will not be available.

How can I confirm the fan is running at the correct 12 V 0.32 A after installation?

Check the motherboard hardware monitor or BIOS fan-speed readout; it should report a stable RPM that matches the PWM duty cycle you set.
