Compact 40 mm 12 V case fan

The Zyvpee AFB0412MB is a 40 mm square, 15 mm thick case fan that runs on 12 V and draws 0.13 A. It uses a two-pin power connector and a ball bearing for continuous operation in tight chassis spaces.

Replaces noisy 40 mm sleeve-bearing fans

The jump is worth it when an existing 4015-size fan has become loud or unreliable; the ball bearing and 28.5 dBA rating at 6000 RPM give a measurable noise and lifespan improvement over worn sleeve-bearing units.

Limited to fixed-speed two-pin control

The two-pin interface means the fan runs at full 6000 RPM whenever powered, with no PWM or voltage regulation from the motherboard; speed control requires an external resistor or fan controller, and the 40 mm frame restricts airflow compared to larger standards.

Questions about this item

Will the 40 mm by 15 mm frame fit my 4015 mounting holes?

Yes, the fan measures exactly 40 mm square and 15 mm thick, matching the standard 4015 cut-out pattern used on many small-form-factor cases and heatsinks.

How do I connect the two-pin lead without reversing polarity?

The red wire is positive and the black wire is negative; plug the connector onto a 12 V header so the red wire aligns with the +12 V pin — reversing it will prevent the fan from spinning.

When should I expect to replace the ball-bearing fan?

Ball bearings typically run for tens of thousands of hours at 6000 RPM; plan to swap the fan once noise rises above the rated 28.5 dBA or airflow noticeably drops.
