120 mm PWM fan with 2000 RPM

The BGears B-PWM 120 BLUE is a single 120 mm case fan built for standard chassis cooling. It uses a two-ball bearing and 15 aerodynamic blades to deliver 110 CFM airflow at full speed. The PWM function allows the motherboard to adjust fan speed automatically based on system temperature. Blue LEDs on translucent blades provide internal lighting.

4-pin PWM and Molex power options

Speed is controlled through a standard 4-pin PWM header connected to the motherboard. A 3-to-4-pin Molex adapter is also included for direct power-supply connection. The fan operates between 500 and 2000 RPM, so minimum airflow depends on the motherboard’s fan curve or BIOS settings. Noise reaches 37.3 dBA at maximum RPM.

Replaces sleeve-bearing or fixed-speed fans

This unit upgrades older sleeve-bearing fans that develop noise over time or 3-pin models that lack automatic speed control. The two-ball bearing extends service life under continuous operation. The jump is worthwhile when a build needs reliable PWM control, higher peak airflow, or blue LED illumination in a 120 mm mount.

Questions about this item

Should I pick the 500 RPM minimum or the 2000 RPM maximum for my build?

The fan runs between 500 and 2000 RPM under PWM control; the motherboard selects the speed based on temperature, so you do not choose a fixed speed.

What does 110 CFM actually deliver inside a case?

At full speed the fan moves 110 CFM of air through a 120 mm frame, giving strong airflow for CPU coolers or front intake while producing 37.3 dBA.

How does the 4-pin PWM connector limit fan control?

The 4-pin PWM header lets the motherboard vary speed from 500 to 2000 RPM; the included 3-to-4-pin Molex adapter allows fixed-voltage operation from a PSU instead.
