Single 120 mm PWM case fan

The BGears b-PWM 120 Black is a single 120 mm case fan with a 25 mm frame. It uses a 4-pin PWM connector for automatic speed control between 500 and 2000 RPM. A 3-to-4-pin Molex adapter is also supplied for direct power-supply connection. The unit weighs 102 g and carries a 60000-hour life expectancy rating.

Builders needing high airflow at moderate noise

This fan delivers 110 CFM at its 2000 RPM maximum, producing 37.3 dBA. The 15-blade impeller and 2-ball bearing suit users who want strong airflow for radiators or restrictive meshes without a separate controller. Buyers who need silent operation below 20 dBA or fans larger than 120 mm should look elsewhere.

110 CFM maximum airflow at 2000 RPM

The peak airflow of 110 CFM at 2000 RPM is the key figure for matching this fan to a thermal load. At zero static pressure the flow reaches 1.51 CFM, while maximum static pressure is rated at 3.7 mmH2O. The PWM range of 500 to 2000 RPM lets the motherboard balance cooling and acoustics automatically.

Questions about this item

How long before the 2 Ball bearing needs replacement?

The manufacturer rates the 2 Ball bearing for 60000 hours of operation before replacement is typically required.

What limits continuous running at 2000 RPM?

The operating temperature ceiling is 70°C; sustained loads that push the fan housing beyond this will throttle speed first.

How loud and how much power at full 2000 RPM all day?

At 2000 RPM the fan draws 6.84 W and produces 37.3 dBA; the 4-pin PWM connector lets the motherboard lower both when full speed isn't needed.
