4056 12V 1.4A case fan

This 40 mm by 56 mm case fan operates at 12 volts and draws 1.4 amps. It fits tight spaces that require the 4056 form factor. The unit is supplied new and ready for installation.

Sustained-load behaviour

Continuous operation at the rated current keeps airflow steady without the drop-off seen in short bursts. The 12 V supply maintains consistent speed during extended use. Heat dissipation remains stable across the 40 mm by 56 mm frame. Builders needing lower noise or lower power draw should consider other models.

Questions about this item

How loud and hot does the 4056 fan get when running continuously at 12 V and 1.4 A?

The fan draws 1.4 A at 12 V, so sustained operation will produce noticeable airflow and motor heat; expect a high-speed whine typical of 40 mm boosters.

What connector or mounting hardware do I need to install the 40×40×56 mm unit?

You need a 12 V power source with a compatible two-pin or three-pin header and four M3 screw holes spaced for a 40 mm square frame.
