Compact 40x20mm chassis fan

The Zyvpee AD0412US-C50 is a 40mm square, 20mm thick case fan designed for tight mounting points in small-form-factor builds or as a targeted spot cooler on a heatsink. It runs on 12 V drawing 0.14 A through a simple two-pin power connector.

Sleeve bearing and fixed-speed operation

A sleeve bearing keeps acoustic output low at the expense of a shorter lifespan compared with ball-bearing alternatives, while the sub-1600 RPM rating means airflow is modest and non-adjustable. The two-pin wiring provides power only, so speed cannot be modulated by the motherboard and the fan runs at full voltage whenever the system is on.

Limited to static-pressure tasks in confined spaces

The 40x20mm footprint restricts this model to situations where a larger frame simply will not fit, such as inverter coolers, thin rack units or legacy GPU shrouds. Without PWM control or a tachometer wire the host cannot monitor rotation or reduce noise during idle periods, making it unsuitable for builds that demand variable cooling curves.

商品問答

How fast does the 2-pin AD0412US-C50 spin at full speed?

The sleeve-bearing fan runs below 1600 RPM when supplied with 12 V.

What clearance does the 40×20 mm frame need inside the case?

Allow a 40 mm square footprint and 20 mm depth for the black plastic housing.

How do I connect the two wires without reversing polarity?

Match the red lead to +12 V and the black lead to ground on the motherboard header.
