Zyvpee GW12E12MS1CB-52 Z20 12V 0.22A 3-pin case fan

Compact 12 V case fan

This 12 V ball-bearing fan connects via a standard three-pin header and draws 0.22 A. It is intended for builders who need a small, non-illuminated airflow device for tight chassis spaces or auxiliary cooling loops. Buyers seeking high-static-pressure models for dense radiator stacks or RGB-equipped units for showcase builds should look elsewhere.

Simple three-pin installation

Mount the fan with four screws and plug the three-pin connector into any 12 V motherboard or controller header; the third wire provides speed reporting so the BIOS can monitor rotation. No PWM wire is present, so speed control relies on voltage reduction rather than duty-cycle signalling, and some modern headers default to full voltage unless configured otherwise.

Fixed-speed 12 V operation

The motor runs at a constant 12 V input and cannot accept 5 V or variable-voltage headers without an external regulator. Because the connector lacks a fourth PWM pin, the fan cannot respond to PWM curves from fan-control software, limiting automated thermal management to voltage-based profiles only.
