Zyvpee AD0412HX-C50 40mm 4020 12V .11A 2 Wires case fan

Compact 40 mm hydraulic fan for tight builds

The Zyvpee AD0412HX-C50 is a 40 mm by 20 mm case fan designed for small-form-factor chassis, inverter coolers or auxiliary CPU spots where larger fans cannot fit. It runs on 12 V and draws 0.11 A through a simple two-wire connector, making it compatible with standard motherboard or controller headers. The hydraulic bearing and non-LED black frame suit builders who want a low-profile airflow upgrade without lighting distractions.

Quiet low-power operation at idle

In normal use the fan spins at modest speed, keeping noise low while moving enough air for light workloads or passive-component cooling. The two-wire design means speed is governed by voltage, so acoustic output stays consistent without PWM signalling overhead. Power draw remains at the rated 0.11 A, adding negligible load to a 12 V rail and leaving headroom for other peripherals.

Steady airflow under sustained load

When the system runs hot for extended periods the hydraulic bearing maintains stable rotation without the rattling that can develop in sleeve alternatives. Continuous 12 V operation keeps airflow constant, preventing the thermal throttling that short bursts cannot resolve. The compact 4020 footprint still limits total volume moved, so it suits targeted spot cooling rather than whole-case exhaust.
