Replacement Side Blower Fan

This 40x50x10mm DC fan operates at 12V and draws 0.24A using a double ball bearing design. It is built as a direct replacement for the Delta BFB0412HA 4510 model used in laptop cooling pads. Buyers who need a different voltage, connector pinout, or mounting pattern will not be able to use this unit.

Double Ball Bearing Construction

The double ball bearing reduces friction and extends service life compared with sleeve alternatives. Its side blower orientation pushes air across the heatsink fins rather than straight down, matching the original Delta airflow path. Installers must verify the physical photos and part number before fitting, as no universal bracket or adapter is included.

Tested Thermals and Power

Each unit is tested before shipping to confirm it spins freely and draws the rated 0.24A at 12V. The double ball bearing keeps acoustic output consistent over time without the rattling that worn sleeve bearings develop. Users seeking higher static pressure or lower noise than the original Delta specification should look elsewhere.
