140 mm PWM case fan with red LEDs

The BGears b-PWM 140 Red is a 140 mm case fan designed for chassis cooling. It features a two-ball-bearing motor and 15 aerodynamic blades. Red translucent blades and four red LEDs provide internal lighting. A 4-pin PWM connector and a 3-to-4-pin Molex adapter are included for motherboard or power-supply connection.

Sustained-load behaviour

PWM control adjusts speed between 500 and 1800 RPM based on thermal demand. At the 1800 RPM operating point the fan moves 110 CFM of air while producing 35.8 dBA of noise. The two-ball-bearing design maintains consistent rotational stability during extended high-speed operation. The 25 mm frame depth fits standard 140 mm mounting points.

Upgrade context

This unit replaces a single 140 mm fan that lacks PWM speed regulation or LED illumination. The jump is worthwhile when the existing cooler runs at fixed voltage, generates excessive noise at full speed, or cannot match the 110 CFM airflow ceiling. Builders needing multiple fans or a different colour scheme should look elsewhere.

Questions about this item

How loud is the b-PWM 140 Red at its maximum 1800 RPM speed?

The fan produces 35.8 dBA at 1800 RPM, which is a quiet level suitable for continuous operation in a typical build.

Does the b-PWM 140 Red need a separate fan controller to run?

No, it connects directly to a motherboard 4-pin PWM header or a PSU Molex connector using the included adapter; no extra controller is required.

Will the 25 mm thick 140 mm frame fit the same mounting points as my older 140 mm fans?

Yes, the 140 mm square frame with standard screw holes matches the common 140 mm mounting pattern used on older cases and radiators.
