Compact 40×40×10 mm case fan for tight builds

This 12 V, 1 W fan fits the 4010 form factor and uses a velocity transducer for speed feedback. It suits small-form-factor cases, 1 U servers or embedded appliances where a standard 120 mm fan cannot be mounted.

Mounts directly to 40 mm screw points

The low 1 W draw leaves headroom on a 12 V rail and the transducer signal lets the motherboard or controller monitor RPM without a third PWM wire. Builders needing PWM control or larger airflow should look elsewhere.
