Zyvpee KF0420B1H-BE 40x20mm 12V .13A 2-pin case fan

Compact 40 mm case fan

The Zyvpee KF0420B1H-BE is a 40 by 20 mm DC cooler that runs on 12 V and draws 0.13 A through a two-pin connector. Ball-bearing construction keeps the rotor stable during continuous operation. The black frame carries no lighting, so it suits plain chassis interiors.

For tight clearances, not high airflow

Builders fitting a fan into a 40 mm mounting hole will find the slim 20 mm depth compatible with narrow brackets. Systems that demand strong static pressure or PWM speed control should look elsewhere because this unit offers neither a four-pin header nor high-pressure blades.

Two-pin 12 V power connector

The fan connects directly to a 12 V two-pin header, delivering fixed voltage without speed signalling. If the motherboard or controller only provides four-pin PWM headers, an adapter or voltage reducer will be required before installation.
