40mm Magnetic-Bearing Case Fan

The SXDOOL 40mm fan uses a magnetic bearing and a 2-pin connector to deliver 10-15 CFM airflow at 4500-4999 RPM. It fits tight 40x40x20mm mounting points in compact chassis or small-form-factor builds. Rated at 12V and 0.05A, it suits low-power cooling slots.

Upgrade from Sleeve-Bearing 40mm Fans

Replaces older sleeve-bearing 40mm units that develop rattle or seize after extended use. The magnetic bearing offers a 50000-hour service life and a 5-10 dBA noise range, making the swap worthwhile when silence and longevity matter more than maximum airflow. The 15cm lead reaches nearby headers without extension cables.

Sustained Load Behaviour

Under continuous operation the magnetic bearing maintains consistent speed without the friction rise common in sleeve designs. Noise stays within the 5-10 dBA band and airflow remains steady at 10-15 CFM. The 12V 0.05A draw keeps thermal contribution minimal during long sessions.

Questions about this item

Will this 40mm fan line up with standard 40mm case mounting holes?

The housing is 40 by 40 by 20 millimetres, matching the common 40mm frame size used in most cases and heatsinks.

What is the tricky part when plugging the 2-pin connector onto a motherboard header?

The small 2P interface and 15cm lead are short, so the header must be close and the keyed plug oriented correctly before pressing it on.

How long before the magnetic bearing typically needs replacement?

The bearing is rated for 50000 hours of continuous running at the 4700 RPM reference speed.
