80 mm high-speed case fan

The BGears b-Blaster 80 is an 80 mm case fan built around a dual ball-bearing motor rated for 3500 RPM. It moves up to 62 CFM of air while producing 39 dBA of noise. The 3-pin connector reports speed to the motherboard and a 3-to-4 pin adapter is included for direct power-supply connection. It suits compact cases, PSU replacements or CPU heatsinks that accept an 80 x 25 mm frame.

Best for high airflow in tight spaces

This fan suits builders who need maximum airflow from an 80 mm slot and accept the audible noise that comes with 3500 RPM. It is not for systems that require PWM speed control, near-silent operation or larger fan mounts. The fixed-voltage 3-pin design means speed scales only with voltage changes, not a dedicated PWM signal.

3500 RPM and 62 CFM at 39 dBA

The single specification that decides fit is the combination of 3500 RPM, 62 CFM airflow and 39 dBA noise. If the target component or case can tolerate that acoustic level and the 80 mm mounting pattern, the fan delivers the stated cooling performance; otherwise a lower-speed or larger-diameter alternative is required.

Questions about this item

Does the b-Blaster 80 come with a Molex adapter or must I buy one separately?

The fan includes a 3-to-4 pin Molex adapter so it can connect to either a motherboard 3-pin header or a power-supply Molex connector without extra parts.

Should I choose the 3500 RPM version or a lower-speed model for a quiet build?

This model runs at a fixed 3500 RPM and produces 39 dBA; if you need quieter operation you would need a different fan with a lower RPM rating.

What does the 62 CFM airflow figure mean once the fan is installed in a case?

At 3500 RPM the fan moves up to 62 CFM through its 80 mm frame, delivering strong heat dissipation for case, power-supply or CPU-heatsink mounting.
