Compact 40 mm cooling fan for tight builds

This 40 mm square fan fits the narrowest CPU cooler mounts and small-form-factor chassis where larger rotors cannot be installed. It runs on a 12 V rail and draws only 0.16 A, so it adds minimal load to the power budget. The two-pin connector provides simple voltage control without PWM signalling. Ball-bearing construction gives a longer service life than sleeve alternatives in the same footprint.

Ball bearing and two-wire simplicity

The ball-bearing motor reduces friction and resists dust ingress better than hydraulic or sleeve types, keeping acoustic output stable over time. With no LED or third wire, the fan integrates cleanly into legacy headers or basic fan controllers that only supply power and ground. The black frame and blades blend into dark interiors without drawing visual attention. No additional cables, adapters or mounting hardware are included in the package.

Targeted airflow for low-TDP coolers

At 40 by 40 by 20 mm the fan delivers focused airflow across narrow heatsink fins typical of low-profile or embedded CPU coolers. It handles thermal loads from modest processors and chipset heatsinks where space forbids a larger frame. The thin 20 mm profile clears tight side-panel clearances and stacked daughter boards. Builders needing higher static pressure for dense radiators or larger tower coolers should look elsewhere.

Questions sur cet article

How long will the ball bearing last before the FD1240-A2041D needs replacement?

The 12 V, 0.16 A ball-bearing motor is rated for continuous operation; typical service life reaches tens of thousands of hours before bearing wear requires a swap.

What limit appears first when this 40 mm fan runs at 12 V non-stop?

Sustained 12 V, 0.16 A draw makes the motor's thermal ceiling the first bottleneck; airflow drops once the coil hits its temperature ceiling.

How much noise and heat does the FD1240-A2041D produce during all-day use?

Ball-bearing design keeps acoustic output low while the 12 V, 0.16 A input generates only modest warmth inside a 40x40x20 mm frame.
