Compact 40 mm case fan

The Zyvpee AD0412HB-C50 is a 40 mm by 20 mm ball-bearing fan designed for tight chassis spaces or targeted component cooling. It runs on a 12 V supply and draws 0.10 A through a standard two-pin connector. The non-LED black frame keeps the appearance neutral in any build.

12 V 0.10 A power profile

At 12 V and 0.10 A the fan delivers modest airflow suited to low-heat zones such as chipset heatsinks, small-form-factor cases or inverter enclosures. The two-pin design means speed is fixed by voltage, so there is no PWM headroom for automatic ramping under load. It runs out of steam quickly when asked to move air through dense fin stacks or restrictive filters.

Two-pin voltage control limits

A two-pin connector ties fan speed directly to the voltage supplied by the header, preventing motherboard PWM control or software fan curves. Builders who need variable speed tied to temperature sensors will find this interface too rigid. The fan is therefore best reserved for constant-speed roles where simplicity outweighs dynamic control.

Questions about this item

Will the 12 V .10 A 2-pin connector work with the 3-pin headers on my older motherboard?

The fan uses a 2-pin 12 V .10 A connector; it fits a 3-pin header by leaving the sense pin empty, so the fan runs at full speed without PWM control.

How can I confirm the AD0412HB-C50 is spinning correctly after installation?

Listen for the ball-bearing motor and feel airflow through the 40 mm frame; the 12 V .10 A draw means it should start immediately when the system powers on.

Does the box include mounting screws or only the 40x20 mm fan itself?

Only the AD0412HB-C50 4020 fan with its 2-wire lead is supplied; screws or adapters for the 40 mm frame must be sourced separately.
