Compact 40 mm case fan for tight builds

The Zyvpee RDM4010B is a 40 mm square frame fan designed for small-form-factor cases and auxiliary cooling spots where larger units will not fit. It runs on 12 V and draws 0.07 A through a two-wire power connector, making it suitable for basic motherboard headers or fan controllers that supply 12 V DC. The ball bearing and non-LED black frame target builders who need simple airflow without lighting.

Check 40 mm mounting holes and two-pin header

Verify that your chassis or heatsink has 40 mm mounting points and that the 40 * 10 mm dimensions clear surrounding components. Confirm the power source provides a two-pin 12 V connection because the fan uses a 2-wire lead without PWM or speed reporting. Ensure the 0.07 A draw is within the header or controller current limit.

Ball bearing and no LED keep maintenance simple

The ball bearing reduces friction compared with sleeve designs, extending service life in continuous operation. The absence of LEDs means no extra cables or software control are required, so installation is limited to the two power wires. These traits make the fan a straightforward replacement or upgrade for legacy 4010 mounts.

Questions about this item

Does the Zyvpee RDM4010B ship with mounting screws or only the fan itself?

The box contains the 40 mm fan with its two-wire lead; mounting screws are not included and must be sourced separately.

How do I decide between the RDM4010B and a larger frame size for my build?

The RDM4010B fits a 40 x 10 mm cut-out and draws 0.07 A at 12 V; choose it only when the chassis or heatsink specifies that exact 4010 footprint.

What airflow can I expect once the 12 V 0.07 A fan is installed in a live system?

At the rated 12 V and 0.07 A the ball-bearing motor spins to its specified speed, delivering the manufacturer's rated airflow for a 4010-sized frame.
