Replacement Fan for DELTA BSB0405LA

This replacement cooling fan is built for laptops that use the DELTA BSB0405LA model. It suits technicians and owners who need to swap out a worn or noisy original unit. The part arrives new and tested before shipping. Compatibility depends on matching the exact part number.

5 V .30 A Three-Pin Connector

The fan runs on a 5 V supply drawing .30 A through a three-pin header. This connector layout fits the original mounting points and power delivery without adapters. Day-to-day, the direct plug-in keeps installation simple and maintains the laptop's thermal control loop.

Restores Original Cooling Performance

Installing this fan returns the system to its factory cooling capability when the original fails. The jump is worth it when temperatures climb or the old bearing becomes audible. Buyers who need a different voltage, pin count or form factor cannot use this part.

Questions about this item

Does the 3‑pin connector carry PWM control or only voltage regulation?

The 3‑pin header supplies 5 V power and a tachometer signal; speed is controlled by varying voltage rather than PWM.

What screw spacing or bracket style does the BSB0405LA frame use for mounting?

The fan frame matches the original DELTA mounting holes; verify hole‑to‑hole distance against your old fan before fitting.

Which way should the airflow arrow point when installing the replacement fan?

Align the arrow so air blows toward the heatsink; installing it backwards is the common mistake that causes overheating.
