120mm PWM ARGB Case Fan

This Silverstone Technology SF120B-ARGB is a single 120mm case fan with fluid dynamic bearing and addressable RGB lighting. It targets builders who want adjustable cooling and lighting in a standard 120mm mounting slot.

Suited for PWM-controlled airflow up to 2500 RPM

The wide 0 to 2500 RPM range suits systems that need both silent idle and strong load cooling. Buyers needing a different fan diameter, a non-ARGB version, or a multi-fan kit should look elsewhere.

Shark Force blade with three-phase six-pole motor

The distinctive Shark Force blade pattern and three-phase six-pole motor deliver higher torque and smoother operation than conventional designs. Modular cables separate power and ARGB connections for cleaner routing.

Questions about this item

Should I pick the 120 mm SF120B-ARGB or a different size?

This model is a 120 mm fan; choose it when your case or radiator has 120 mm mounting points.

What does the 2,500 RPM top speed mean once the fan is installed?

At full PWM duty the fan spins at 2,500 RPM, delivering maximum airflow and static pressure for heavy loads; at lower duty cycles it runs slower and quieter.

What does the 4-1 pin ARGB connector cap in practice?

The 4-1 pin ARGB connector limits lighting control to motherboards or controllers that support standard 5 V addressable RGB signalling.
