Compact 40 mm maglev fan for tight builds

This OEM Industries fan measures 40 by 10 mm and uses a maglev bearing with a 3‑pin 5 V connection. It draws 1.2 W and has no LED lighting. The square frame fits small form factor cases, rack enclosures and embedded boards where space is limited.

Steady airflow at constant 5 V supply

At the rated 5 V the motor maintains a consistent speed without the voltage sag seen on PWM‑controlled headers. Maglev bearing friction stays low over long periods, so airflow does not decay during extended compute or storage workloads.

Low noise and minimal power draw in daily use

The 1.2 W rating keeps heat output negligible inside a sealed chassis. Maglev operation eliminates bearing rumble, leaving only a soft air‑rush sound at full voltage. No extra power phases or fan controllers are required.

Questions about this item

How much heat and noise does the 40 mm Maglev fan produce when running continuously?

The maglev bearing reduces friction, so the 40 mm fan runs quietly and generates minimal heat at its rated 5 V and 1.2 W.

What power source and connector does the KDE0504PFV1 need to operate?

It requires a 5 V supply and a standard 3-pin fan header on the motherboard or controller.

Will this 40 mm square fan fit the mounting holes on my older 4010 chassis?

Yes, the 40×10 mm frame matches the common 4010 mounting pattern used on legacy cases and coolers.
