Compact 40 mm fan for tight builds

The OEM Industries KD0504PFB3-8 is a 4010 square cooling fan designed for small-form-factor systems and replacement cooling in industrial or embedded hardware. It runs on a 5 V supply and draws 0.4 W through a two-wire connection.

Check voltage header and mounting holes

Verify that your board or controller provides a 5 V fan header with the correct pin spacing for the two-wire lead. Confirm the 40 mm square footprint and 10 mm thickness match the available clearance and screw pattern in your chassis or heatsink assembly.

Low power draw and ball-bearing operation

At 0.4 W the fan adds minimal load to a 5 V rail and keeps heat output low in normal use. The ball bearing design supports continuous rotation with consistent acoustic levels, avoiding the wear-related noise increase seen in sleeve alternatives.

Soalan tentang produk ini

Does the KD0504PFB3-8 ship with mounting screws or a power adapter, or must those be sourced separately?

The item is the 40 mm square fan only; mounting hardware and any power adapter are not included and must be obtained separately.

The listing shows a single 5 V 0.4 W 2-wire version — how do I confirm this is the correct one for my board header?

Match the 5 V 0.4 W rating and two-wire connector to your motherboard or controller header specifications; no other voltage or wire-count variants are offered for this model.

What does the 0.4 W power draw mean for actual cooling performance in a live system?

At 5 V and 0.4 W the fan delivers modest airflow suited to low-heat components or tight spaces; expect limited cooling capacity compared with larger or higher-wattage units.
