Cooling fan with two-ball bearing

The BGears b-PWM 140 Black is a 140 mm case fan built around a two-ball bearing for extended service life. It spins between 500 and 1800 RPM, pushing up to 110 CFM at a stated 35.8 dBA. A 4-pin PWM connector enables motherboard speed control, while a bundled 3-to-4-pin Molex adapter allows direct power-supply connection. Fifteen aerodynamic blades are designed to maintain airflow pressure through restrictive grilles or radiators.

Suited for high-airflow builds.

This fan suits builders who need strong airflow for CPU coolers, radiators or high-heat chassis and who prefer mechanical bearing durability over fluid-dynamic quietness. PWM control lets the system reduce speed at idle, yet the minimum 500 RPM still produces audible airflow. Buyers targeting near-silent operation or who want addressable lighting will not find those features here. The single-fan pack also means multi-fan arrays require separate purchases.

1800 RPM maximum speed defines peak performance

The 1800 RPM ceiling determines the 110 CFM peak airflow and the 35.8 dBA noise rating quoted by the manufacturer. At this speed the two-ball bearing delivers its highest cooling capacity, making the figure the primary check for thermal-headroom planning. If a build requires lower maximum noise or a different airflow target, the fixed 1800 RPM limit becomes the deciding constraint.

Domande su questo articolo

Does the fan require a 4-pin PWM header on the motherboard for speed control?

The fan ships with a mini 4-pin connector for PWM control and a 3-to-4-pin Molex adapter for direct PSU power; either connection works.

Will the 25 mm thickness fit in a case designed for slim 15 mm fans?

At 25 mm thick it exceeds the 15 mm slim profile, so verify your chassis has standard 140 mm clearance before installing.

How can I confirm the fan is running at its rated 1800 RPM maximum?

Check the RPM reading in BIOS or fan-control software while the PWM duty cycle is at maximum; the reported speed should approach 1800 RPM.
