Replacement fan for AUSU notebooks

This OEM Industries KSB0405HA cooler is a direct-replacement fan assembly built for AUSU notebook CPUs. It delivers a 5 V .3 A draw through a standard 4-pin connector. The ball-bearing design targets reliable airflow in thin-and-light chassis.

Verify connector pinout and voltage before fitting

Confirm that the original cooler uses a 4-wire 5 V interface matching the KSB0405HA specification. Check the motherboard header spacing and screw-hole pattern against the replacement unit. Ensure the BIOS recognises the new fan curve after installation.

Ball-bearing motor runs at 5 V .3 A

The low-voltage motor keeps power draw minimal for notebook thermal envelopes. Ball bearings reduce start-up friction and maintain consistent speed under load. Expect a steady acoustic profile suited to office and classroom environments.

Questions about this item

Does the package include mounting hardware or thermal paste, or do I need to buy them separately?

The cooler is supplied as a fan-only unit with a 4-pin connector; mounting hardware and thermal paste are not included and must be purchased separately.

How do I know if the Delta KSB0405HA 5 V 0.3 A version fits my notebook?

Match the 5 V 0.3 A rating and 4-pin connector to your original cooler's label; this model is listed for ASUS notebooks using the KSB0405HA part number.

What does the 0.3 A current draw mean for actual cooling performance?

At 5 V the fan draws 0.3 A, giving a low power profile suited to thin-and-light notebooks where thermal headroom is limited.
