Zyvpee KD1204PKV1 40×20 mm fan

The Zyvpee KD1204PKV1 is a 40 mm square case fan with a 20 mm thickness. It runs on 12 V power and draws 1.2 W through a two-pin connector. The maglev bearing supports speeds between 1600 and 1999 RPM. This compact cooler suits tight builds that need a small form-factor airflow solution.

Two-pin power and maglev bearing

The two-pin connector delivers fixed 12 V supply without pulse-width modulation control. The maglev bearing reduces mechanical friction compared with sleeve or ball alternatives. No LED lighting is fitted, keeping the frame plain black. The physical photos show the exact item you will receive.

Builders fitting 40 mm mounts only

This fan fits only 40 mm mounting holes with 20 mm clearance. Systems requiring PWM speed control, larger diameters or RGB illumination cannot use it. Buyers who need variable fan curves or higher static pressure should look at other models.

Questions about this item

How long before the maglev bearing in the KD1204PKV1 needs replacement?

The maglev bearing has no physical contact, so it typically outlasts sleeve or ball bearings and rarely requires replacement under normal use.

What stops the fan from spinning faster than 1999 RPM under sustained load?

The motor is rated for a maximum of 1999 RPM, so voltage and firmware limit it to that ceiling even during continuous operation.

How much heat does the 1.2 W motor add to the case after hours of running?

At 1.2 W the motor contributes very little waste heat, and the 40 × 20 mm frame dissipates it quickly, keeping case temperatures virtually unchanged.
