BGears b-PWM 140 Blue 140mm case fan 2000 RPM 110 CFM 2 Ball Blue LED

140 mm PWM case fan with blue LEDs

The BGears b-PWM 140 Blue is a single 140 mm case fan built for chassis cooling. It uses a two-ball bearing and 15 aerodynamic blades to move air through the system. A 4-pin PWM connector allows automatic speed control from the motherboard, while a bundled 3-to-4-pin Molex adapter provides a direct power-supply option. The translucent blue frame and four blue LEDs add a coloured lighting accent.

Upgrade from fixed-speed

This model replaces basic fixed-speed fans that cannot adjust to thermal load, and sleeve-bearing units that tend to wear faster. The jump is worth it when you want PWM control between 500 and 1800 RPM for quieter idle operation and up to 110 CFM under load. The two-ball bearing extends service life compared with sleeve alternatives, and the included Molex adapter lets older systems without 4-pin headers benefit from the same airflow range.

Suits builders who want adjustable 140 mm airflow

It fits users seeking a single PWM-controlled 140 mm fan that delivers up to 110 CFM at 35.8 dBA and includes blue LED illumination. The package contains only the fan and adapters, so buyers who need a multi-fan kit, a dedicated hardware controller, or a different LED colour should look elsewhere.
