BGears BG30033 140mm case fan 15 blades 1500 RPM 96.5 CFM 29.6 dBA 3-pin

140mm 3-pin case fan

The BGears BG30033 is a 140mm case fan built around a 15-blade impeller and a fluid dynamic bearing. It connects via a standard 3-pin header and spins at 1500 RPM to deliver 96.5 CFM of airflow. The white frame includes both metal and anti-vibration rubber mounting screws for flexible installation. This fan suits builders who need a single high-airflow cooler for a standard chassis fan slot.

Upgrade from lower-airflow stock fans

The 15-blade design moves 96.5 CFM at 29.6 dBA, a measurable step up from basic 120mm fans that typically produce 82.6 CFM at 26.5 dBA. The jump is worth it when a case has 140mm mounting points and the CPU or GPU runs hot enough to need more volume than a smaller or slower fan can supply. Builders limited to 120mm slots or 4-pin PWM control cannot use this model.

Sustained-load behaviour

The fluid dynamic bearing maintains consistent rotation precision and anti-shock performance during extended operation, preventing the speed drift and noise rise common in sleeve-bearing units after months of continuous use. All cables are sleeve-wrapped to resist abrasion in tight routing paths. The 1500 RPM speed holds steady under load, keeping airflow at the rated 96.5 CFM without the thermal throttling cycles seen in fans that rely on aggressive speed curves.
