Zyvpee KDE1204PFVX 40 mm Maglev Fan

This 40 mm case fan runs on 12 V and draws 1.8 W through a two-pin connector. The Maglev bearing keeps noise low at speeds below 1600 RPM. Its 40 x 10 mm frame fits tight CPU cooler cut-outs and small-form-factor chassis.

Suits builds needing a compact 12 V replacement

Buyers who need PWM control, a three- or four-pin header, LED illumination, or a larger frame size should look elsewhere. The fixed two-wire design offers no speed signalling, so it cannot report RPM to the motherboard.

Key spec: 40 x 10 mm two-pin 12 V Maglev

This single combination of mounting footprint, voltage, connector and bearing decides whether the fan fits your cooler bracket and header. Verify those four points against your hardware before ordering.

Questions about this item

Does the maglev bearing in the Zyvpee KDE1204PFVX need lubrication or replacement over time?

Maglev bearings use magnetic levitation instead of physical contact, so there is no oil to dry out and no sleeve to wear down. The fan is rated for continuous operation without scheduled bearing maintenance.

What limits the airflow of this 40 mm fan when it runs continuously at 12 V?

The motor is specified at 1.8 W and the speed ceiling is below 1600 RPM, so the aerodynamic curve of the 40×10 mm frame becomes the bottleneck before the motor reaches its thermal limit.

How much noise and heat does the fan produce during all-day use?

At 1.8 W the motor generates very little waste heat, and the maglev design keeps acoustic output low even during continuous operation.
