This DC centrifugal blower fan is specified into projectors and thermal modules, where the air has to be forced across a dense heatsink fin stack rather than simply moved. The bearing choice is worth thinking about: hydraulic bearings run quieter for consumer equipment, dual-ball last far longer where the fan mounts horizontally or runs hot. Available at 5V, 12V and 24V with screw mounting, plus free spare parts support and OEM or ODM branding.
