Compact 40mm DC fan for tight builds

The SXDOOL YW04010005BS is a 4010 form-factor case fan that runs on 5V DC at 0.30A. It fits 40x40mm mounting holes in small-form-factor chassis, embedded boards or replacement cooler shrouds where larger fans cannot be installed. The double ball bearing is rated for maintenance-free operation.

Double ball bearing reduces service needs

The maintenance-free double ball bearing eliminates the sleeve-bearing wear that causes rattling or seizure in confined airflow paths. This allows continuous low-voltage running without scheduled lubrication or replacement intervals. The bearing choice also keeps acoustic output consistent over the unit’s service life.

5V 0.30A limit restricts airflow headroom

The fixed 5V 0.30A input caps the maximum rotational speed and static pressure the 4010 frame can generate. Builders needing higher CFM for dense radiator stacks or filtered intakes will find the electrical ceiling restrictive. No PWM or voltage-regulation header is present, so speed cannot be modulated by the motherboard.

Questions about this item

How long will the double ball bearing last before it needs replacement?

The maintenance-free double ball bearing is designed for continuous operation without scheduled replacement.

What limits performance when the fan runs at 5 V and 0.30 A continuously?

The fixed 5 V supply and 0.30 A draw set the maximum airflow the 4010 frame can deliver.

How much noise and heat does the mute cooling fan produce during all-day use?

The mute design keeps acoustic output low while the 5 V 0.30 A input limits heat to a minimal level.
