40 mm 24 V axial fan for targeted cooling

The OEM Industries F412R-24MB is a 40 mm axial fan designed for direct component airflow in industrial or embedded systems. It operates on a 24 V DC supply through a two-pin connector. The unit suits builders who need a compact, single-fan solution for tight enclosures. It is not suited for standard desktop CPU sockets that require larger heatsink assemblies or PWM control.

Ball-bearing motor with two-wire power

The fan uses a ball-bearing design intended for continuous axial airflow at the rated voltage. Only the two power wires are present, so speed reporting or automatic regulation is not available. Acoustic output and power draw will follow the fixed 24 V input without software adjustment. Builders needing variable speed or motherboard fan headers should verify compatibility before installation.

Bare fan without mounting hardware or software

The package contains the fan unit only; no brackets, screws, ducting or control software are included. Integration depends entirely on the host chassis or custom bracket design. Users must provide their own mounting method and wiring termination. No RGB lighting or additional accessories are supplied.

Questions about this item

How do I install the 40mm F412R-24MB fan and which step is often missed?

Mount the fan using its four screw holes, connect the 2-pin header to a 24V DC source, and verify the airflow direction arrow points toward the heatsink — many forget to check the arrow.

What maintenance will the ball-bearing 412 model need over time?

The sealed ball bearings require no lubrication; periodically remove dust from the blades and frame with compressed air to keep airflow steady.

What limit appears first when the 24V axial fan runs continuously?

Continuous 24V operation makes bearing wear the first limiting factor; dust buildup on the 40mm blades reduces airflow before the motor overheats.
