120 mm PWM case fan

The BGears b-PWM Vortex 120 RGB is a single 120 mm case fan with a 25 mm frame and hydraulic bearing. It connects via a standard mini 4-pin PWM header for automatic speed control. The black frame carries no LED lighting, keeping the look understated for any build.

Suits quiet-focused builds; not for RGB lighting

Builders who want low noise will appreciate the 28 dBA maximum rating and a speed range of 600 to 1800 RPM. The hydraulic bearing supports long-term reliability at modest cost. Buyers who want addressable RGB illumination or a multi-fan kit should look elsewhere.

Fits standard 120 mm mounts

The fan slots into any 120 mm case opening and draws power from a motherboard PWM header. At full speed it delivers up to 101 CFM airflow and 13 mmH2O static pressure, clearing heat from dense fin stacks. The slim 25 mm profile leaves clearance for radiators or cable routing behind the fan.

Perguntas sobre este artigo

Does my motherboard need a 4-pin PWM header to run the b-PWM Vortex 120 RGB?

Yes, the fan uses a mini 4-pin PWM connector so a 4-pin header is required for speed control.

Will the 120 mm frame and 25 mm thickness fit in the same mounting points as my existing 120 mm fans?

The fan measures 120 x 120 x 25 mm, matching the standard 120 mm mounting pattern used by most cases and radiators.

How can I confirm the fan is spinning within its 600 to 1800 RPM range after installation?

Monitor the RPM reading in BIOS or fan-control software; it should stay between 600 and 1800 RPM with a tolerance of ±10 %.
