Compact 40 mm 12 V case fan

The SXDOOL RDM4025S1 is a 40 mm square frame fan that runs on a 12 V supply and draws .14 A. Its two-wire lead provides simple power connectivity for tight chassis positions or small-form-factor builds where space is at a premium.

25 mm thick low-profile cooling

The 25 mm depth fits slim enclosures and restricted clearances while moving air across VRM heatsinks or drive cages. Builders needing higher static pressure, PWM speed control or larger airflow volumes will need a different fan design.

Questions about this item

Will the 12V .14A 2-wire fan run safely on an older motherboard header that only supplies 5 V?

The fan is rated for 12 V operation; at 5 V it may spin slowly or not start, so an older 5 V header cannot guarantee reliable cooling.

How can I confirm the 40x40x25 mm RDM4025S1 is spinning correctly after installation?

Enter the BIOS or fan-control software and verify the header reports an RPM reading above zero while the system is under load.
