Zyvpee KD0504PKB2 40 mm 5 V DC fan

The Zyvpee KD0504PKB2 is a compact 40 mm by 20 mm case fan that runs on 5 V DC power and draws 1.0 W. It uses a two-wire connector and has no LED lighting. The black frame suits small-form-factor chassis and CPU coolers that need a thin, low-voltage airflow source.

Suits builds with 5 V two-pin headers

This fan fits systems that provide a 5 V two-pin header and have room for a 20 mm thick frame. Buyers who need PWM speed control or a three-pin or four-pin connector cannot use this model. Units that require higher static pressure or a larger frame should consider other options.

5 V 1.0 W two-wire power specification

The decisive specification is the 5 V 1.0 W two-wire power input. If the motherboard or controller supplies a different voltage or uses a three-pin or four-pin header, the fan will not operate correctly. Verify the header type and voltage before purchase.

Questions about this item

How can I verify the KD0504PKB2 is spinning correctly after installation?

Connect the 2-wire lead to a 5 V header and confirm the blades rotate smoothly without vibration or noise.

What comes in the box with the KD0504PKB2 and what must I source myself?

The fan unit only; you will need a 5 V 2-pin power header or adapter and mounting screws for the 40 mm frame.

Which KD0504PKB2 variant should I choose for a 40 mm by 20 mm mounting area?

This single model matches the 40x20 mm footprint and 5 V 1.0 W rating; no other capacity or version is offered.
