Compact 40mm Axial Fan

The Zyvpee KDE1204PKV1 is a 12V DC axial case fan measuring 40 by 20 millimetres. It draws 0.8 watts and uses a three-wire power connector. A maglev bearing handles the rotation. No LED lighting is fitted.

Suited for tight 40mm mounts

This unit fits cases or devices that accept a 40mm square frame with a 20mm depth. Builders working with larger standard frame sizes cannot use it. The three-wire lead provides speed monitoring but not PWM control, so boards needing a four-pin header should look elsewhere.

Maglev bearing for low friction

The maglev bearing reduces mechanical contact, lowering noise and extending operating life compared with sleeve or ball alternatives. This single feature determines whether the fan meets the reliability target for a given build.

Questions about this item

How do I confirm the 40x20mm maglev fan is running correctly after installation?

Connect the 3-wire plug to a 12V header, power on the system and verify the blades spin smoothly with no vibration or unusual noise from the maglev bearing.

What comes in the box and what must I source separately?

The package contains the Zyvpee KDE1204PKV1 12V .8W 40*20mm fan unit only; mounting screws and any fan splitter or adapter cables are not included.

Which version of the KDE1204PKV1 should I choose for a 12V 3-wire header?

The listed KDE1204PKV1 MS.AF.GN model is a 12V .8W 3-wire maglev fan, so it matches a standard 12V 3-pin motherboard header directly.
