Compact 40×40×20 mm axial fan

The Zyvpee KD0504PKB2 is a 40 mm square, 20 mm thick DC axial fan rated for 5 V and 1.0 W. It uses a two-wire power connection and a ball bearing for continuous operation in tight enclosures such as routers, switches, printers or small-form-factor CPU coolers. The black frame carries no LED lighting.

Suits low-voltage chassis with two-pin headers

Builders working on 5 V platforms that provide a simple two-pin header will find this fan a direct fit. It is not intended for systems that require a third wire for speed reporting or a fourth wire for PWM control, nor for builds that need higher airflow than a 40 mm frame can deliver.

Two-wire 5 V 1.0 W power spec

The sole decisive specification is the two-wire 5 V 1.0 W power interface; the motherboard or device must supply exactly that voltage and connector type for the fan to run.

Questions about this item

How often will the ball bearing need replacement?

The ball bearing is sealed and rated for continuous operation without scheduled replacement intervals.

What thermal limit appears first when the fan runs continuously?

The 1.0 W motor at 5 V stays within its design envelope, so the bearing temperature limit is reached before any electrical limit.

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

The 40×20 mm axial design moves air quietly at low RPM; heat output equals the 1.0 W electrical draw.
