Purpose and audience

The Zyvpee ASB0412MA is a 40 mm ball-bearing case fan built for tight spaces such as small-form-factor PCs or network switches. It suits builders who need a compact 12 V cooler with a standard four-wire connector.

Decisive specification

The fan draws 0.08 A at 12 V through a 4-pin PWM header, allowing motherboard speed control. Verify that your board provides a 4-pin header and 12 V supply before purchasing.

Sustained-load behaviour

Ball-bearing construction maintains consistent rotation during continuous operation without the wear patterns seen in sleeve alternatives. The 40*10 mm frame fits shallow mounts while delivering steady airflow over long sessions.

Questions about this item

What does the 0.08 A current draw mean for my motherboard's 4-pin header?

The fan draws 0.08 A at 12 V, which is well within the typical 1 A limit of a standard 4-pin CPU or chassis fan header.

How does the 4-pin connector control the fan speed in practice?

The fourth wire carries a PWM signal from the motherboard, letting the board vary the fan speed dynamically instead of running at a fixed voltage.

Will the 40 mm by 10 mm frame fit my small-form-factor case or heatsink?

The fan measures 40 mm square and 10 mm thick, so it fits any 40 mm mounting pattern with at least 10 mm of clearance.
