Compact 40 mm ball-bearing fan

The Zyvpee AD0412HB-D56 is a 40 mm by 15 mm case fan built around a ball bearing for durable rotation. It draws 0.12 A at 2 V DC and targets small-form-factor or embedded systems where a low-profile cooler is required. The black, non-LED frame keeps the appearance neutral inside any chassis.

Three-pin connector and mounting

A standard three-pin power connector supplies both power and a tachometer signal so the motherboard can monitor speed. The 40 mm square footprint with 15 mm thickness fits tight clearances around compact CPU sockets or industrial boards. Ball-bearing construction reduces friction noise compared with sleeve alternatives at similar dimensions.

Limits of the 2 V DC interface

Operating at 2 V DC restricts use to headers or controllers that provide this specific voltage; standard 12 V fan headers will not drive it correctly. The 0.12 A current rating caps airflow potential, so the fan suits light thermal loads rather than high-wattage processors. No PWM wire is present, so speed control depends on voltage regulation alone.

Questions about this item

What does the 3-pin connector limit for the AD0412HB-D56 fan?

The three-pin connector supplies 2 V and 0.12 A directly, so speed is fixed by voltage and cannot be PWM-controlled.

Will the 40 mm by 15 mm frame fit my chassis fan slot?

It fits any standard 40 mm mounting hole pattern with 15 mm clearance behind the frame.

How do I install the AD0412HB-D56 and what step is often missed?

Align the four screw holes, secure with 40 mm fan screws, then attach the three-pin plug to the motherboard header — forgetting the plug leaves the fan dead.
