BGears b-Blaster 40 40mm 2 Ball 9000 RPM 17 CFM 3 Pin

Compact 40 mm case fan

The BGears b-Blaster 40 is a 40 mm by 28 mm case fan built around a dual ball bearing for extended service life. It spins at 9000 RPM and delivers 17 CFM of airflow at a listed 36 dBA. The unit ships as a single black fan with four mounting screws included.

3 pin 12 V connection

The fan uses a standard three pin 12 VDC connector that provides a speed signal output to the motherboard header. No separate controller is included so speed management relies on the board or a compatible fan hub. Its 28 mm thickness fits tight clearance zones such as small form factor cases, power supply housings or CPU heatsink mounts.

Builders needing high speed spot cooling

This model suits builders who need a high RPM 40 mm fan for targeted airflow in confined spaces. It is not suited for silent builds or for anyone requiring PWM control, RGB lighting or larger fan dimensions.
