40mm 12V case fan for tight builds

This SXDOOL FD124020EB-N is a 40 by 40 by 20 millimetre axial fan designed for compact chassis or component spot-cooling. It runs on 12 volts DC with a 0.17 amp draw and spins at 8900 RPM to deliver 10.5 CFM of airflow. The double ball bearing is rated for long service life in continuous operation.

Check 3-pin header and 40mm mounting points

Verify that your motherboard or fan controller provides a standard three-pin connector and that the mounting holes match the 40mm square pattern. The fan operates between 7 and 13.2 volts, so ensure your voltage source stays within this range. At 33.5 dB the noise level is noticeable in quiet environments.

Suits small-form-factor and replacement cooling

Builders fitting a 4020-sized slot in mini-ITX cases, GPU shrouds or industrial enclosures will find the 9.2 mmH₂O static pressure useful for restricted airflow paths. Buyers who need larger diameters, PWM speed control or lower acoustic output should consider other form factors.
