Compact 40mm chassis fan

The Athena Power FANC-4020BW3H is a 40mm by 20mm case fan built for industrial PC chassis where space is tight. It uses a ball bearing and a 3-pin power connector to deliver 10 to 15 CFM of airflow at speeds above 7000 RPM. The black plastic frame carries CE and UL certification for safety compliance.

Straightforward 3-pin mounting

Installation consists of aligning the 40mm square frame with the chassis mounting holes and plugging the 3-pin connector into a compatible header. The supplied hardware in the complete package secures the fan without extra tools. Misaligned screw holes or a header that only accepts 4-pin PWM control are the typical reasons a builder has to re-seat the unit.

Steady airflow under load

At sustained speeds above 7000 RPM the fan maintains its rated 10 to 15 CFM flow while noise stays between 25 and 30 dBA. The ball bearing is designed for continuous operation without the slowdown that sleeve bearings can exhibit after prolonged heat exposure. The air-cooled plastic construction resists deformation during extended duty cycles.

Questions about this item

How can I confirm the FANC-4020BW3H is spinning correctly after installation?

Listen for the ball-bearing whir and check that your BIOS or monitoring software reports a speed above 7000 RPM with noise between 25 and 30 dBA.

What comes in the box and what must I supply myself?

The package includes the single 40 mm by 20 mm black fan with a 3-pin connector; you only need a compatible motherboard header or fan controller.

Which version of this fan should I choose for my build?

This model is offered in one configuration — 40 mm frame, 20 mm thickness, ball bearing, 3-pin power, no LED — so select it when those exact specifications match your chassis.
