Zyvpee AD0412LB-C52 40mm 4020 12V .11A 3 Pin Case Fan

Compact 40 mm Cooling Fan

The Zyvpee AD0412LB-C52 is a 40 mm by 20 mm case fan built for tight spaces inside small-form-factor chassis or industrial enclosures. It runs on 12 V DC at 0.11 A and connects through a standard three-pin header, providing basic speed reporting without PWM control. Ball-bearing construction targets longer service life in continuous-operation scenarios. Black non-LED housing keeps the visual profile neutral.

Suited for Low-Profile Builds

This unit fits builders who need a 4020 footprint to cool compact CPUs, inverter modules or embedded boards where larger fans cannot mount. The three-pin interface works with most motherboards and fan controllers that accept a tachometer signal. Buyers who require PWM speed regulation, higher static pressure, or RGB illumination will not find those features here. Systems that only offer four-pin headers without voltage control should consider other options.

Decisive Specification: 40x20 mm Frame

The 40 mm by 20 mm frame is the single dimension that determines whether this fan can be installed at all. Mounting holes follow the 40 mm square pattern, so any chassis or heatsink designed for 4020 fans will accept it directly. If the available opening is larger, smaller, or uses a different hole spacing, the fan will not fit without modification. Verify the exact cut-out and screw pattern before ordering.
